Depending on weather conditions, this can happen quickly - almost instantly. Your water looks normal one day, and the next time it turns green, green, not water, but a swamp. The green color that you see is the full-blown flowering of algae.

Algae are microscopic plants that fall into pools with rain or are carried through the air, such as dust. Some of them are free floating, while others are attached and cling to the walls of the pool. In any case, you can clean your pool, so do not despair - within one two days your water will be crystal clear.

Instructions for algae control in the pool.

2 Use your test kit to determine the pH level in the pool water. It should be between 7.2 and 7.6. If it is outside this range add pH plus or pH minus to adjust the level.

3 Use a brush for the walls and bottom of the pool to weaken the adhesion of algae to the pool surface.

4 Add unstabilized chlorine in granules (powder) to the pool. The amount of chlorine you add will depend on the volume of your pool (150 grams for every 10,000 liters or about 5 ounces of chlorine for every 2,500 liters of water).

5 Turn on the pump and start the filtration system, during the day chlorinated water circulates and eliminates algae from the water.

6 Collect white sediment from the bottom of the pool using a water vacuum cleaner the next day. Water should be substantially purified if it still has a green color to repeat the "shock" process.

7 Rinse the filter.

8 Add the required amount of water to the pool, the amount of which will decrease during this treatment.

Tips & Warnings

Clean your pool regularly with a vacuum cleaner and keep your pool water balanced (pH should be between 7.2 and 7.6, and free chlorine should be between 1.0 and 3.0 ppm).

During periods of hot weather or when you have a large, water load (a large number of swimmers), perform a “shock” treatment of the Pool every two weeks, this will not allow algae to capture your pool.

After a “shocking” treatment of water in the pool, you should not swim for at least one day. High levels of chlorine can cause eye irritation or skin irritation, as well as damage to bathing suits.


Once your pool was pleasing to the eye of the blue surface of the water, but then strange green formations began to appear on it, more and more, until the pool began to look like a muddy swamp for frogs. Common situation? Believe me, it is often found, and there are techniques that can quickly return your water to a beautiful view. Water blooms in the pool, what should I do?

Let's look at the reasons for the formation of green algae in the pool, how to get rid of it, and what pitfalls can meet on the way to clean water.

Why is water blooming?

Water in the pool becomes green due to the multiplication of microorganisms and algae. If water was not originally prepared, then it is a favorable environment for the development of fungi, viruses and bacteria, and under the influence of sunlight they multiply even faster. If the reservoir is on the street, then the appearance of green water without prevention is inevitable.

Modern filtration systems do not need to know about such problems, but their price is not available to every pool owner, which leads to the search for affordable and equally effective alternatives.

Green Water Disposal Techniques

The easiest way to remove viruses and bacteria from the very beginning is that they easily die from bleach, preparations containing bromine or a solution of hydrogen peroxide. Why is green water in the pool even after chlorination? Because with plants everything is more complicated, despite the fact that they are visible to the human eye. Algae have a protective shell, which disinfectants cannot damage. A competent approach to water purification will be:

  • Mechanical removal of visible algae by the net,
  • The addition of drugs that destroy the membrane and immune system of algae,
  • Chlorination or use of hydrogen peroxide (perhydrol).

Means that can destroy the biological protection of plants are called algaecides.

What is algicide?

Algaecides are used not only to prevent water from blooming in the pool, but also to prevent the appearance of algae, fungi and bacteria. It is better to prevent their appearance than to constantly clean the bottom and walls of the pool from greenery.

If the user does not violate the manufacturer's instructions, then the drugs do not harm human health or pets in any way.

How much algaecide is needed to clean the pool?

The water in the pool turns green, what should I do? What algaecides to buy and how much to add? Preparations for the removal of cyanobacteria (algae) come in different formulations and instructions for use. We bring to your attention 5 popular products with an approximate calculation of dosage and average cost.

  • Astral. One of the available algicides, its cost in stores is 1,500 rubles per 5 liters. It is simple to apply, half a liter of substance per 100 m 3 of water once a week. If your pool is smaller, then calculate the dose proportionally. For example, for a volume of 25 m 3 you need 125 ml,
  • STX-570. It has the same anti-algae properties as Astral, the same dosage, but costs twice as much. However, there are adherents who claim that it is more effective,
  • Zodiac Anti Alg. This drug requires a little more than competitors - half a liter per 40 m 3 per week, which is more than 2 times more than Astral. Zodiac costs about 2500 rubles for 5 liters,
  • Bayrol Aquabrom. The most expensive and most economical algicide of all presented. It costs more than 3000 rubles per canister, the consumption is 500 ml per 10 m 3 daily. In a week, 3.5 liters of the drug will be spent on such a pool. Experts note that the effectiveness corresponds to the costs, the drug destroys algae and microorganisms in the shortest possible time,

Before using any of the algaecides, read the instructions in detail. She can give you recommendations for use specifically in your case. Remember that the water will then come into contact with the human body, so strictly follow all the applicable regulations.

Why are cyanobacteria still alive?

It happens that the use of the best algicide does not lead to the desired results. Why is the water green in the pool? I added what you need!

  • Few disinfectants. Algicide is not a killer of algae, it only violates their protective structure so that other drugs eliminate them. Pay attention to the amount of perhydrol or chlorine that you add to the pool along with algaecides,
  • Violation of the acid-base balance in water (pH). The norm is from 6 to 8. If the limits are violated in any direction, then the algaecides will lose their properties against algae,
  • Expired drugs. All chemicals have expiration dates, often the result of the removal of cyanobacteria is not achieved due to expired canisters. The problem with green water in the pool is not so often relevant, and in the utility room there is an algicide, bought several years ago,
  • Violation of instructions. An attempt to add funds “by eye” may fail. Making recommendations for use, the manufacturer takes into account many factors in the chemical laboratory. If the quantity per cubic meter of water is indicated, then, at a lower dosage, the drug will not be able to destroy the cell structure of the algae shell.

These were the main reasons for the likely failures in cleansing the pools of cyanobacteria. If you do everything right, but the result is disappointing, there is a possibility of falsification of the product.

Conclusion

So, water blooms in the pool, what should I do? At least two components must be involved in the fight against green water in the pool: algicide and a disinfectant. They should be used according to the instructions. Quantity should be calculated based on the size of the pool.

To prevent pool water from blooming, use algaecides and chlorination according to the prevention instructions on the labels.

How to clean the bowl of greens? Which remedy is better to use?

The pool, especially the one located on the street, is particularly pleasing to its owners, especially during high temperatures. The water in it provides an excellent opportunity to freshen up without leaving your home. But, like everything that surrounds us, the pool, and especially the water, requires special care and maintenance. The garbage that the wind brings and we leave, various kinds of pollution, bacteria, as well as the process of flowering water - these are the problems that should be addressed.

Why does the water turn green

If debris and pollution can be easily dealt with by cleaning the pool or changing the water, then a greened liquid is a real problem. Why does it arise?

The flowering of the water surface is especially active in the warm season. This process is caused by the multiplication of special microorganisms, namely, green and brown algae. They are not like the algae we are used to. These are microscopic organisms that multiply at an incredible speed and densely cover the bottom and walls of the pool. The breeding process takes place in an ideal environment for them:

  • Humidity,
  • Sunlight in sufficient quantity
  • Heat,
  • "Food" - leaves, garbage and everything that can get into the pool, serves as a good treat for these microorganisms.

Such an environment is more than conducive to flowering water and this process is just a matter of time, if you do not take appropriate measures.

Ways to fight

In order to prevent the flowering process, it is necessary to ensure that the liquid in the pool is constantly as clean as possible. To do this, install a filter in the pool. It will help maintain the required level of cleanliness in the pool. In addition, periodically, the fluid must be changed, because no matter how high-quality the filter is, it will eventually become unusable. When draining fluid from the pool, take a brush and try to clean the floor and walls from contamination. For this, various chemicals can be used that are designed to get rid of this kind of problem.

If the water still turned green, then it is necessary to take drastic measures. The green water in the pool requires an integrated approach. Filters not only clean the pool of algae, but they can’t do it completely. Therefore, chemicals are also used here.

For starters, you can try to treat the pool fluid with chlorine. This method will be quite effective if there are not so many algae in the water, and the process of their reproduction is at the initial stage. But it is worth remembering that the use of chlorine can cause allergic reactions. Therefore, be careful and careful, and also remember that the level of concentration of this chemical in a liquid should not exceed 3 mg per 1 liter of water.

You can work with other chemicals that are more effective and less harmful. These are algaecides. They are designed to effectively get rid of fungus, mold and algae. The composition of these substances includes coagulants that dissolve quickly enough in water and envelop all the existing dirt, bacteria or algae. Thanks to the resulting coating, such particles of treated dirt can be easily filtered and removed with a filter.

The first portions of chemicals and organics enter the pool with water from the water supply system, from the well. In the industrial regions of Russia there are no perfectly clean water sources - any, even only the flooded pool water needs to be treated before bathing. Even underground water obtained from an artesian well contains a polluting inorganic substance (metals, fluorine, etc.), which negatively affects the body of the swimmer.

Distilled and rain water is recognized as completely safe. But after filling it, the outdoor pool in a short time will be contaminated with dust particles and microorganisms, corrosion products, algae and foliage. At the same time, bathing people are a serious source of pollution for the bowls of each pool - in 20-30 minutes of swimming a person brings more than 20,000 microorganisms into the water.

To combat pollution of the water surface of the pool, it is important to correctly use chemical agents, monitoring the water composition constantly. Fortunately, now there are plenty of tools and devices that support the quality of basin water.

The correct pH of the pool water

In a chemically pure state - H 2 O - water is neutral. However, in natural sources and in the water supply network, various substances are dissolved in it, shifting the chemical properties of water closer to acid or alkali. Use the table below to evaluate the effects of changes in the acid-base balance of water.

Water "rusty color", dark red deposits on the sides of the pool - metal corrosion.

Blond hair and bathing clothes turn green - corrosion of copper.

The seams of the mosaic cladding are exposed - their grout is destroyed.

Irritating to eyes and skin.

The optimum pH range of basin water is 7.2-7.4 (most importantly, not higher than 7.6). Maintaining such an acid-base balance will prevent the development of negative chemical reactions in the pool, ensure the effectiveness of disinfectants and protect against eye and skin problems.

The chemical composition of the water that fills the bowl, as well as the chemicals contained in the cleaning and disinfecting agents used by the owner, have an effect on the pH level of the pool. PH measurements should be carried out daily, taking immediate measures to regulate the aqueous acid-base balance when the level goes into critical zones (see table).

To simplify pH control, it is convenient to use automatic pool systems that monitor the chemical composition regularly and make independent adjustments (the introduction of appropriate drugs). Only, the pool owner needs to replenish stocks of corrective chemicals (pH regulators) in the bins of such a system on time.

Pool chlorination

The oldest and still the best method of disinfection, whose use is based on the saturation of water with chlorine-containing substances. Two groups of such agents are known - “fast” chlorine and “slow” chlorine.

Fast Chlorine Preparations . Once in the water, they decompose immediately with the release of chlorine and, during chemical reactions, most of the chemical binds to inert (inactive) compounds (chloramines). “Quick” chlorine is usually used at the beginning of the swimming season - at the start of the pool. Shock chlorination enables quick and highly effective disinfection of basin water. Such drugs are introduced into the pool one-time and manually.

Slow Chlorine Preparations . React with water slowly, with a gradual release of a chlorine disinfector. Providing biological purity of water in the pool, means with "slow" chlorine are used in it continuously.
The simplest dispenser for “slow” chlorine-containing tablets is a small plastic flask. Water is pumped through a dispensing flask, dissolving little tablets, the dissolved chlorine enters the pool. The disadvantage of such a dispenser is that there is no possibility of continuous monitoring of the chlorine content in an artificial reservoir. Even dispenser models that allow manual control of the chlorination process are poorly effective. Suppose you set up the device according to the results of measuring chlorine compounds in water with reagents, but with each bath, the water level of chlorine will drop due to the reaction with organics, and at night it will be released in an excessively high volume. You do not want to swim in the morning due to the unbearable smell of bleach.

Systems for automated supply of chlorine-containing reagent (liquid) are the most effective. The first type is proportional supply devices capable of saturating water with chlorine in dosed portions according to the schedule set by the timer. The second type is a water chlorine auto-regulation station along with maintaining an optimal pH level. This system independently introduces small doses of reagents at the signal of its sensors, which analyze water quality constantly.

Иные химические препараты для водоочистки бассейна, чем содержащие хлор, менее эффективны. Поэтому хлорные реагенты применяются по-прежнему, хотя они могут образовывать опасные соединения с водой и даже вызвать взрыв. Modern water treatment plants are designed with the minimum use of chlorine. It is better to disinfect the pool with systems that use combinations of drugs of different chemical composition - it is safer for swimmers.

Water purification with active oxygen

In the recent past, active oxygen and its reagent, hydrogen peroxide, have been widely used to disinfect pools in European countries and Russia. Entering water, hydrogen peroxide enters into a chemical reaction with the release of oxygen, and that - kills organic pollutants. It was believed that active oxygen completely displaces chlorine-containing reagents, but - in addition to the high cost of such systems, they revealed critical shortcomings.

First of all, the oxygen-containing reagent decomposes almost instantly in water and the oxygen released by it releases into the atmosphere too quickly, without having time to destroy many pollutants. I had to fill the pool with an excessively large amount of hydrogen peroxide in order to try to remove organics. But a high amount of “oxygen” reagent did some harm to the swimmers - the hair was discolored, the skin was damaged and there was a pain in the eyes.

Disinfecting a public pool with hydrogen peroxide is unprofitable - too expensive. It takes a lot of reagent, because its disinfecting effectiveness is low. However, in private pools to eliminate blooming of water with hydrogen peroxide is quite possible.

Disinfection of the pool with ozonation

The use of oxygen in its active state - ozone (O 3) - allows you to instantly destroy organic objects in basin water (oxidize them). Ozonation, in fact, is a natural water treatment procedure, only many times accelerated. Ozonation stations generate ozone from the air using ultraviolet radiation or corona electrical discharge.

Ozone can oxidize microorganisms 15 times, and spore bacteria - 500 times faster than chlorine. After ozonation, the pool water does not smell anything, it acquires a bluish tint. Excess ozone does not react with water - it becomes ordinary oxygen and goes into the atmosphere.

Among the disadvantages of pool ozonation are especially significant:

  • the high cost of ozone generating equipment,
  • ozone is unstable and does not last long - it disappears almost immediately after entering the water,
  • Ozonation stations are capable of disinfecting only the volumes of water passing through them. As a result, the surface layer of water remains untreated,
  • ozone is toxic, in large volumes - explosive.

To achieve complete purity of basin water, an ozone generator should be used together with a chlorine station that maintains an optimally low concentration of chlorine. This will allow you to achieve a beautiful view of the water surface and completely eliminate organic pollutants without increasing the amount of chloramines.

UV pool treatment

Ultraviolet is deadly for bacteria, microorganisms and viruses. Its radiation effectively decomposes organic matter and, importantly, chloramines. The principle of action of ultraviolet rays on organics is based on their penetration deep into the cellular structure of microorganisms, violating their ability to reproduce. The chemical composition of water, regardless of the degree of intensity of UV radiation, does not change.

Ultraviolet disinfection is used in conjunction with a chlorine station, increasing the quality of the pool water by eliminating free chlorine and chloramines. The UV station is mounted in the pool circulation line, immediately after the mechanical cleaning filter and in front of the water heating device.

It is impossible to build a swimming pool disinfection system only with ultraviolet water treatment - microorganisms are eliminated only at the time of the UV installation, and those volumes of water that pass through the device are disinfected. For the effectiveness of UV disinfection, it is important to maintain the purity of water from mechanical impurities, chemically eliminate excess iron. You can find a large selection of UV water disinfection systems in the company Pragmat.

Salt electrolysis of the pool

The production of chlorine - a water disinfecting agent - comes from salt, whose formula is NaCl. Chlorine-containing reagent is produced by electrolysis from salt previously dissolved in the pool.

The electrochemical reaction performed by the electrolysis station causes the formation of hypochlorous acid in the pool, which oxidizes the organic matter (algae, microorganisms, etc.). A by-product of electrolysis - hydrogen - is discharged to the surface of the water and escapes into the atmosphere. Other reaction products - HCl and NaOH are converted chemically to H 2 O (water) and back to NaCl (sodium chloride), which will again be involved in electrolysis.

There is no cheaper chlorine than table salt. About 5 kg of salt is needed to disinfect a cubic meter of water per year. Sensors of the electrolysis station monitor the amount of chlorine in the water, calculating its redox potential. Constantly, salt does not need to be added - the station will supply raw materials for the production of a disinfecting reagent independently and in small portions.

In addition to the light salinity of the basin water, there is one serious drawback of the "electrolysis" disinfection - this method is not able to eliminate organic pollutants by 100%. Bacteria survive in the corners of the pool bowl, in the knocks and joints of the lining, near the water surface. The only way to eliminate them is by shock disinfection with “fast” chlorine.

Ionizing pool disinfection

The most advanced water disinfection system. Principle of action: a weak current is supplied to the electrode block located in the filtration system of the pool, copper and / or silver ions are released into the water. For viruses and bacteria, silver ions are fatal, and copper ions block the development of algae. Also, the ionization of water by copper helps to remove any microimpurities from it - Cu ions cause coagulation of mechanical microparticles into larger ones, which the filter element can catch.

The greatest effectiveness of the ionizing disinfection system is demonstrated in small pools, while in large pools there is a periodic need for shock chlorination. Note that the effects of metal ions on humans have not been fully investigated.

At the end

In addition to pH reagents and organic pollutants, pools of significant water volume require the use of additional chemicals - algaecides, coagulants and flocculants.
Herbicide group preparations - algaecides - are necessary to eliminate “blooming” water in the pool bowl.

Fatal to algae, algaecides do not harm humans. Unlike microorganisms, algae are able to adapt to the standard means of combating them - to develop in the presence of chlorine, other chemicals, to heal the walls and pipes of the pool, "hiding" from disinfectants. Algicidal treatment of the walls and pipes in the pool should be carried out before filling the water, or they should be added to the full body of water in shock quantity.

The pool sand filter is not capable of holding too small particles of contaminants. Using coagulants and flocculants, it will be possible to “mold” such pollutants into larger aggregate forms that can be cleaned in filters or from the bottom with a pool vacuum cleaner.

Today, the market is filled with all kinds of accessories for pools, and it can be difficult to decide what to add to the pool so that the water does not bloom. The first thing that comes to mind is to install a special filter, but without adding special tools, this solution is not as effective as it seems at first glance. In addition, it can be difficult to provide them, for example, with a small inflatable pool. To understand the issue, we consider some reagents according to their functional purpose.

Flowering prevention

So that the water does not bloom, they add a whole class of reagents under the common name - algaecides. For example, the filter is not able to solve the flowering problem, since algae often cover the pool walls. It is necessary to add algaecides at the first signs of the appearance of algae in the pool - turbidity, the occurrence of plaque on the walls. You can also add algicide, even if the water has not bloomed, for prevention.

PH adjustment

For people with sensitive skin, swimming in a pool where the water does not have an appropriate acid-base balance (pH level) can cause great discomfort in the form of dry skin, rashes and other troubles. For this category of swimmers, the addition of pH corrective products is mandatory. In addition, a normal pH level (6.8 - 7) reduces the occurrence of limescale and, as a result, helps to save an expensive filter. How much and what means to add to water is decided by testing with a special device, as well as the attached instructions. The form of release may vary, depending on the manufacturer.

Turbidity Elimination

So that the water does not bloom, you can use different means, the most important thing is to follow the manufacturer's instructions. The water in the pool must be clean and no savings will justify health problems. Follow the simple rules for caring for pools, and your vacation will never be overshadowed.

In the case when the filter cannot cope with the turbidity of the water caused by flowering or is completely absent, special substances - coagulants come to the rescue. Coagulants should be added with caution, especially if there is a filtration system. In this case, the addition of a liquid version is recommended. Solid, in the form of tablets, is more suitable for pools that do not have a filter.

Need regular care

The home pool requires special care and attention. The reservoir, which no one is watching, will be covered with leaves, garbage, and the water in it will turn into murky and green. Such swimming equipment looks unsightly, emits fetid odors, and is dangerous for the health of children and adults. In it you can slip and fall, get an infection. Therefore, many owners or their managers are interested in the question of how to clean the pool of greenery.

Remember! It’s easier to prevent the appearance of turbidity and “blooming water” than to fight it! The shorter the reproduction period of pathogenic microflora, the faster it can be defeated.

How to clean the pool of greenery?

The fight against clouding of water depends on the volume of the reservoir, the material from which it is created, the “bloom flooding” of the water. With a small inflatable tank, they do it simply: they lower the water, wash the walls. After drying in the sun, you can again fill the pool with fresh water. In large bodies of water, tiled or made of other materials, such methods of combating greening and clouding of water are used as:

How to clean the pool with hydrogen peroxide?

To clean the ponds, a 37% hydrogen peroxide solution called perhydrol is used. Purification of the water surface is carried out due to the release of a large amount of active oxygen. The process of cleaning the pool with hydrogen peroxide is carried out at the rate of 700 ml perhydrol per cubic meter of water. A pool with 12 cubic meters of liquid will need 8.4 liters of hydrogen peroxide. If the reservoir is heavily polluted, then the dose can be increased to 1.5 liters per 1 cubic meter. After such exposure, the water will become clean and will remain so for a month. Then the treatment must be repeated, reducing the dose of peroxide by 2 times.

Hydrogen Peroxide Pool Benefits

Cleaning the pool with hydrogen peroxide is a simple but reliable method, ensuring the purity of the water surface for at least a month. Its advantages:

  • efficiency,
  • profitability
  • lack of an unpleasant smell, color,
  • fast volatilization per day,
  • harmlessness
  • lasting result.

The owners choose a way to combat the turbidity of the water in the pond, depending on how much they can invest in the cleaning process. Of course, if the pool is located on the territory of a residential building, you should worry about more effective ways of processing it. For country pools, a method using hydrogen peroxide is suitable. But still, the choice is yours!

Prevention methods

Cleaning the pool of algae is a long and time-consuming task. Therefore, it is better to take some preventive measures than to get rid of the flowering that has already arisen. However, the color of algae is not always greenish, so you need to pay attention to the signs of rapid flowering:

  • The slippiness of the walls of an artificial reservoir.
  • The appearance of foam on the water.
  • The appearance of a specific smell.

Settled mud at the bottom of the pool

If you notice one or more of these “symptoms,” it’s time to take decisive action. However, not all means have the desired effect.

Bedspreads and tents can be used, but they do not protect the pool from flowering. Such coatings are good to prevent large debris from entering the water area. However, disputes are not held by awnings due to the small size of the former.

Chlorine preparations are necessary, but they need to be combined with other substances. Otherwise, a dense shell appears on the algae, protecting them from the action of chlorine.

However, certain rules allow you to avoid flowering:

  • Active filtration of pool awnings.
  • Rinse the filter periodically.
  • Timely cartridge replacement in the event of clogging.
  • If the pool operates in difficult conditions, the filter is allowed to operate around the clock.
  • The use of chlorine preparations in combination with algaecides (means that destroy algae),
  • Prevention of excessive water stabilization. For this purpose, stabilized chlorine must be alternated with non-stabilized (developed using calcium hypochlorite).

What to do if the water has already bloomed?

The methods of struggle are determined by the stage at which the owners decided to deal with the trouble. From children's containers of an inflatable type, water is simply drained, the walls are cleaned. Then for some time the product is kept in the sun, after which it can again be filled.

Real adult pools are harder to clean. Then cleaning the tank is done without a new filling. Generally, the reservoir must be sanitized and recycled.

Disinfection is carried out by adding algicides to the tank. As a result, algae stop developing. However, in this case, pathogenic bacteria do not die. They are destroyed using preparations containing chlorine. It is sold in various forms - in the form of a liquid, powder, tablets or granules.

The main condition is to comply with the dosage, depending on the volume of the water area. If bathers experience discomfort, reduce the dose or change the drug. Bathing should give a person pleasure, not trouble.

The most effective way are tablets. They are thrown into the water - foaming occurs. Foam is removed by filtration. Specialized bottom vacuums are also used.

Recently, a method of adding rehydrol (hydrogen peroxide) to water has been widespread. It is not worth using hydrogen peroxide from pharmacies, since the percentage of its concentration is extremely small. Use rehydrol in plastic cans. It can be found in specialized shops for pools or some construction stores.

Rehydrol concentration for pool:

  • 30-40% rehydrol - 0.7 l. peroxide per 1 ton of water,
  • > 40% rehydrol - 0.5 l. peroxide per 1 ton of water.

The “duration” of hydrogen peroxide depends on the quality of the water. On average, it is 2-3 weeks.

The process of cleaning the pool requires the contractor to comply with certain measures:

  • For a while, you should wear old worn clothes: drops of chlorine can ruin the color of the fabric - white spots will appear on it.
  • A water sample is available even in stores where pools are sold - the service is provided monthly and even with computer diagnostics. Then you can solve the problems in the early stages.
  • A special net is needed to remove leaves and debris. The procedure is performed every day. Thus, the owners rid themselves of the need for periodic more complex work.
  • Chlorine is kept at a dose of 1-3 million. As a result, algae cease to develop.
  • Do not add unfamiliar substances to the tank! Only well-known cleaners need to be used. Otherwise, new problems will appear!
  • Mixing water with chemicals requires extreme caution. Chemicals are added to water, but not vice versa.
  • Do not mix chemicals under any circumstances! Otherwise, an unpredictable chemical reaction can be achieved.
  • Contact with chlorine products means the utmost caution for you. Otherwise, the “experimenter” will have a sore throat, cough and irritation of the mucous membrane of the eyes, as well as the skin and lungs.

How to clean the bowl of greens? Which remedy is better to use?

The pool, especially the one located on the street, is particularly pleasing to its owners, especially during high temperatures. The water in it provides an excellent opportunity to freshen up without leaving your home. But, like everything that surrounds us, the pool, and especially the water, requires special care and maintenance. Мусор, который приносит ветер и оставляем мы, различного рода загрязнения, бактерии, а также процесс цветения воды – вот те проблемы, с которыми следует бороться.

Рециркуляция

A special system of filters and pumps is mounted in the pool, during the circulation, the water is purified, and it comes back free from pollution. The size of the particles that it takes from the water depends on the type of filter; modern, expensive devices are able to clean almost to perfect condition. You can read how the sand filter for the pool works.

In addition to stationary filters mounted externally, there are also mobile ones. These are mobile or airborne skimmers that collect pollution from the top layer. Usually they are used in frame and inflatable pools.

Today, the latest developments are on sale, these are ultraviolet lamps, ozonizers and ionizers on silver or copper. They allow you to abandon the chemical methods of water purification. However, with a lot of advantages, the main drawback of these gadgets is the crazy price. Few people decide to buy a lamp for cleaning, which is more expensive than the pool itself, it's easier to change the water once every few days. For summer residents, in general, a great way, at the same time, the garden and the garden are regularly watered. Just do not try to put chlorinated water into the business, you can immediately lose all plantings.

The pool in a private house is a common occurrence. Small collapsible models and huge complexes are designed to bring joy to their owners. It's nice to cool off and swim in cool water on a hot day. Although the construction of the pool is not a very cheap pleasure, it is worth investing in its construction.

During the operation of the pool, the biggest problem is the state of the water. If you do not pay attention to the quality of water, its widespread pollution can occur and after a short period of time the pool will simply turn into a “swamp”. About what steps need to be taken so that the water in the pool does not turn green - further.

Causes of Water Pollution

Typically, pools are built in the form of open containers. The construction of a warm pool is rarely used in view of the very high costs of its construction and heating. Open systems are exposed to the environment with all the consequences. Fallen leaves, insects, rainwater and common dust can become sources of pool water pollution. If the site is in close proximity to a natural reservoir, then there is a possibility that amphibians can “settle” in it.

In addition to all of the above factors, it often happens that the water in the pool begins to turn green. This problem is especially acute in the summer, when the average daily temperature becomes quite high. For several days, a beautiful pool with clear azure water can turn into a terribly smelling and unpleasant-looking substance. Moreover, swimming in such water is strictly prohibited, since you can get not quite pleasant consequences.

The reason for staining water in green is the activity of green algae in it. Their appearance can provoke many factors:

  1. Stagnant water. Pool water should be circulated with mandatory filtration. Stagnant moisture is a "paradise" for the propagation of pathogenic bacteria and algae.
  2. The absence of filters or their incorrect operation. This is the most common problem among pool users. Savings when installing filters or replacing them usually lead to a gradual deterioration in water quality.
  3. Ignoring special water treatment products. Savings on various means of combating bacterial pollution of water, as a rule, leads to its flowering.
  4. Use of unfiltered water. This problem is usually inherent in small summer cottages, with a lack of central water supply. If the site is in close proximity to a natural reservoir, then often the water to fill the pool is taken from there. At the same time, along with water, the whole spectrum of bacteria enters the pool capacity, which leads to the rapid blooming of water. To clear river or lake water from harmful flora, even with the help of modern equipment, is quite problematic. Therefore, one of the conditions for a clean pool for a long time is to fill it with clean tap water.

Pool water filtration

The most effective method to prevent the flowering of water in the pool is to filter it. A filter system should be installed at the construction stage of the pool. Be sure to choose it based on the volume of the tank. If the capacity of the filtration system is lower than the volume of the pool, then in this case it will not be able to provide a cleaning rate greater than the propagation rate of algae or bacteria. Despite the rather high cost, the effectiveness of such filters will be zero.

All pool filters have a different design and a set of filter elements. Most often they are made of high-strength plastic, which ensures durability. Plastic practically does not corrode, which prevents rust from entering the water. A special bactericidal plastic prevents the growth of bacteria on the filter surface.

The most popular of the filter elements that are used to purify pool water are as follows:

  • Sand filter. This is the cheapest pool filter that provides good results. The principle of operation of such a filter is to pass water through a layer of calcined sand. At the same time, the latter prevents further ingress of dirt particles into the pool. Water through a skimmer for skimmer pools or an overflow tank for overflow models falls into a special channel at the end of which a pump is installed. It is he who, under pressure, passes water through the sand, which provides filtration. A pressure gauge is installed at the end of the pump, which indicates the pressure in the system. An increase in pressure indicates a clogged filter. In this case, the sand is sifted inside, fried and reused or replaced with a new one. The latter option, although more expensive, will provide better filtering of water in the future.

  • Diatom filters. The principle of operation of such models is the same as in the previous ones. The only difference is the filter medium. Diatom filters use diatomaceous earth instead of sand. This element is a special rock, which was formed from the remains of algae and shells of the oceans. It has a gray or tan color. Due to the high density of the filter material, diatom filters have a very high cleaning quality. They are able to retain in themselves parts of dirt and algae up to 1 micron in size. Thanks to this filter, significant savings are achieved by reducing the use of cleaning chemicals. If the filter is contaminated, diatomaceous earth is removed, followed by its replacement. Such an operation can be done on your own. Specialists who developed this type of filtration claim that when passing through the layers of the filter element, water is saturated with silicon ions, for which it is also called silicon water. It is similar in its properties to a spring or thawed one. Bathing in such a pool stimulates and strengthens the immune system, rejuvenates the skin.
  • Cartridge filters. The filter element of such models consists of a special replaceable cartridge, which includes a layer of paper and polyester. When clogged, they simply change it. Such models are mainly used for filtering small or medium sized pools. The advantages of such filters include an easy change of elements, which can be done independently in a relatively short time.

The use of filters reduces the likelihood of blooming water, as it reduces the concentration of biological substances in the water, which favor the growth of algae. However, their effectiveness should increase due to special chemicals that kill harmful flora in the water. By the way, the main supplier of biological pollutants in the pool is the person who bathes in it. That is why it is recommended to take a shower before bathing.

Chemical Pool Cleaners

Chemical cleaning of pools along with filtration not only prevents the appearance of pollution, but also improves water quality. This process consists of several stages. Let's consider them further.

Acid-base balance regulation . This is a fundamental stage, since many drugs that are designed to cleanse the pool of harmful flora are very sensitive to increasing or decreasing the level of acidity. Therefore, a normal pH level increases their efficiency.

Water disinfection . Water disinfection is designed to kill all the harmful flora in it, which is the cause of pollution and algae growth.

Water disinfection is carried out with drugs of three main groups:

  1. Chlorine based products. Chlorine has a strong bactericidal effect. The use of chlorine is especially effective in the case of severe pollution of the pool, the water temperature in which for a long time was above 28 ° C. Chlorine oxidizes substances that were not retained by mechanical filters, providing deep cleaning. However, the flip side to the use of chlorine is its harmfulness to the human body. Excessive concentration of chlorine in water or its uncontrolled use can lead to poisoning.
  2. The use of drugs based on active oxygen. Differs from chlorination in a milder action. It does not have a pungent odor, does not discharge the mucous membrane of the nose and eyes, and does not foam. It gives an excellent result. With severe contamination, it can be used in conjunction with chlorine-based products.
  3. Preparations based on bromine. They have excellent work results and can be used even in the fight against severe pollution when the use of chlorine is not desirable. In terms of effectiveness, bromine-based preparations are in the middle between chlorine and oxygen. The advantages of such substances is the lack of dependence on the pH level.

The next stage of pool water treatment is algae removal . It is produced using a special group of substances - algaecides. They not only purify water from living organisms so that the water in the pool does not turn green, but also prevent their appearance.

Coagulation . The process consists in the use of special coagulants that turn into flakes and bind to removed particles. At the same time, the formed lumps of dirt increase in size, due to which they become trapped for physical filters.

Water turns green in the pool, how to deal: video

Own pool has long ceased to be a luxury, and has acquired the status of a mandatory attribute. But its operation requires certain work, which must be carried out without fail, as well as monitor the condition of the water. Turbid water in the pool, the appearance of an unpleasant odor or the acquisition of a greenish tint to it indicate that it is time to take action. So that the water does not turn green and is clean and transparent, you should know the reasons for the deterioration of its quality and how to deal with them.

The water in the pool turns green and blooms when various harmful microorganisms and algae begin to appear and multiply in it in large numbers. Their life process is accompanied by the appearance of an unpleasant odor and greening. Under the influence of sunlight, the processes of reproduction of bacteria and viruses are more intense. At the same time, bathers constantly supply them with food, in the form of sweat and secretions, epidermis and existing dirt on the surface of the body.

Turbid and green water in the pool becomes for such reasons:

    The presence of algae. The volatile spores of these microorganisms are quite tenacious, and can spread over vast distances. They are not afraid of climate change, and the most favorable environment for their livelihoods is warm water, which is filled with pools,

Attention! The spread of algae in pools located in enclosed spaces is much slower, but the water in them is also prone to flowering and turbidity.

  • Poor filtration and water circulation. Stagnant water in the tank, a rare replacement of filter elements, a malfunction or lack of pumps, contribute to a more rapid spread of microorganisms,
  • Imbalance of chemicals in the aquatic environment. So that the pool does not turn green and does not become turbid water, chlorine-based products are used, as well as algaecides. If the water balance is at an inappropriate level, then their use is ineffective,

    Attention! The chlorine level in the water should be from 0.3 mg to 0.6 mg, but did not exceed the value of 2 mg. In this case, the pH level for the pool should be in the range from 7.0 to 7.4. One of the options for devices that help determine the levels of chlorine and pH is given in the video.

  • Water stabilization level. The main component, which is a stabilizer and is present in many chlorine-based products for water purification in swimming pools - isocyanuric acid, inhibits the decomposition of chlorine under the influence of sunlight. But its accumulation contributes to the complete cessation of the action of chlorine, and the water becomes over-stabilized. Such water in the pool will certainly bloom, somewhere by the middle of the season, so it is recommended to completely or partially drain it and fill the pool capacity with a new one,
  • Excess iron. Green water in the pool becomes algae, and if it is transparent, but there is a greenish or brown tint in it, then the reason lies in the excessive amount of minerals - iron. To eliminate this trouble should use
