This article tells you what to do to keep the pool water from blooming, and what emergency measures to take if the water does bloom.
Turbid, green, blooming water is the main problem of all pools in the suburban areas of our planet. Especially in the heat: you don’t have time to look around, and instead of transparent, light blue water, some kind of muddy broth flops in the pool.

Why the pool water turns green
The outdoor pool water, well warmed by the sun, creates ideal conditions for the development of various microorganisms. Most of them are safe for humans, but this is because of them the water turns green, becomes cloudy and becomes covered with a film. Therefore, it is up to the pool owner to make these ideal conditions unbearable.
If the water in your pool turns green, it means that:
- the filtration system does not work well enough or does not exist at all;
- the filter is not cleaned in time, it retains cyanobacteria and they multiply right in it;
- disinfectants are either not used, or used incorrectly, or in insufficient quantities – and there is no point in the minimum dose of chlorine;
- chemical contamination is also possible. If there is an excess of cyanuric acid in chlorine-containing pool products, it will destroy the chlorine and cause blooming. There is nothing to help here – the water will have to be drained;
- pool water can bloom from excess iron. In this case, it is green, but transparent and does not have an unpleasant odor.
This problem can be successfully solved by applying an integrated approach.
- constantly remove pollution from the water with a net;
- destroy cyanobacteria with chlorine (or perihydrol);
- for effectiveness, add an agent that destroys the shell of bacteria.
As much as we would like to avoid “all kinds of chemistry”, the water in the pool must be disinfected. Nothing wrong with that. Modern water disinfectants in the correct dosage are safe for humans.
What to do if the pool water turns green
For pool cleaners to work effectively even in small doses, you need to constantly monitor the hardness of the water in it. In general, the values of water hardness are the first thing to know if you have acquired a pool in a suburban area.
It is recommended to always maintain a pH level of 7.0-7.4 in the pool.
If the values are below 7.2, then it is fraught with corrosion of the metal parts of the pool. If the pH is higher than 7.6, swimming in the pool can be dangerous, it may be irritating to the eyes and mucous membranes. At such a pH, lime will settle to the bottom of the pool, and the worst thing is that chemistry works much worse or does not work at all in such wrong water. You can do everything according to the instructions, but the water will still remain green.
Therefore, the pH value must be monitored all the time.
What to do to keep the pool water from turning green
So, here’s how we need to proceed from the day we fill the pool so that the pool water always remains clear:
- find out the degree of water hardness. If the pH level is up to 8 degrees. DH, inorganic chlorine can be used for disinfection, although experts recommend always choosing organic chlorine compounds.
- for prevention, before filling the pool with water, wash its walls with a solution of algicide in a ratio of 1:25. (Algicides are herbicides that break down the cyanobacterial coat and actually kill algae. Sounds scary, but they are not even nearly as dangerous as agricultural herbicides. Available in tablets or liquid form.)
- fill the pool with water.
- run the filter. It is recommended to rinse the sand filter once a week in order to wash away the dirt between the grains of sand, prevent the formation of channels and a sand crust at the bottom of the filter, and loosen the sand.
- evenly distribute on the surface of the water as much algicide as indicated in the instructions.
- measure the pH value with a tester.
- using reactive acid granules, “pH-plus” or “pH-minus”, achieve a pH level of 7.2-7.6. How to do it: Spread the granules evenly over the surface of the water in small portions, check the pH level after each portion. Roughly, to increase the pH by 0.1, pour about 100 g of pH-plus on 10 cubic meters of water; to decrease the pH by 0.1, pour 100 g of pH-minus per 10 cubic meters of water. If the water is hard, the consumption of the product increases. It is highly recommended to maintain a pH level of 7.2-7.6
- Disinfect water by adding chlorine. Only when a constant excess of chlorine from 0.3 to 0.8 mg / l is organized in the pool water, it can be considered that complete sterilization has been achieved. Complete sterilization of water is guaranteed with a constant excess of the amount of chlorine from 0.3 to 0.8 mg / l.
Various means are used for disinfection, from the usual “Whiteness” to “long chlorine” tablets.
Check the amount of chlorine in the water with a tester, add more if necessary. Follow the manufacturer’s recommendations.
Pool water care systems such as three-in-one work well, such as Algicide supplemented with long-lasting chlorine.
Also, in a personal set of chemicals, the owner of the pool must have:
- good detergent for cleaning the edges of the pool;
- powerful cleaners that destroy bacteria during general pool cleaning;
- means that are added to the pool before conservation for the winter.
Various thermometers, water temperature measuring devices, testers showing CL and PH values, dispensers for large “long chorus” tablets are needed.
How to solve problems
If you follow the above rules, there should be no problems with water in the pool. But if they do appear, the situation can almost always be corrected.
