Will Chlorine Kill Algae In a Pool?

Will Chlorine Kill Algae In A Swimming Pool?

Normally Yes. Chlorine kills algae and bacteria by a chemical action called oxidation.

Why Is Chlorine Used In Swimming Pools?

Chlorine is used in swimming pools to act as a disinfectant and to stop the growth of algae.
Without chlorine, most pools would be green within a few days.
It takes chlorine to kill algae. An algaecide is usually used in conjunction with a chlorine shock to kill algae.

Chlorine helps pools by killing off algae microorganisms. It also helps in keeping down the growth of algae.

At What temperature Does Algae Grow In A Pool?

Warm pool water with a temperature over 80°F/26°C and chlorine levels below 1 ppm contribute to algae growth. If there is a high concentration of phosphates in a swimming pool, you can get algae growth even if the chlorine level is higher than 1 ppm. The pool temperature can be checked by a floating solar-powered pool temp thermometer.

Does Algae Grow In Cold Water?

Unfortunately, algae do grow in cold water. It grows at a much slower rate when the water temperature drops below 60°F/15°C. As long as algae get the sunlight they will grow. It uses photosynthesis from sunlight as its method for food to grow. Also, cold water is denser which prevents the movement and growth of those tiny algae microorganisms to move through and get to the surface of the water where there is more sunlight.

What Causes Algae To Grow In A Pool?

The lack of proper swimming pool water filtration and when chlorine levels have been allowed to drop too low. Or when the chlorine is not acting effectively because the water is out of balance, or the pool water has high levels of stabilizer (cyanuric acid). Hot and humid sun conditions as well as if the pool has been used a lot for swimming.

Algae are spores that are blown into the pool or carried into the water in other ways, They then multiply into blooms when the conditions are ideal for them.

These tiny microscopic plants feed on nutrients in swimming pool water given to them by sunlight in order for photosynthesis to work as well as carbon dioxide. Depending on what type of algae is in the pool, the average life expectancy could range from a few days to a year or two.
