The presence of algae in your swimming pool is a sign that the water may be dirty. Dirty pool water can be a breeding ground for all types of bacteria and fungi, which could lead to a lot of diseases and infections. Having algae in your swimming pool makes it unsafe to swim in. Getting rid of algae may be a little daunting for any pool owner but it can be done with the help of materials that can be found in your house.


Bleach is a tried and tested all-around disinfectant and cleaner. The specific type of bleach to use on your pool would be chlorine bleach that has 6 per cent sodium hypochloride. The bleach can be used a spray to get rid of pool algae. The water from the pool must all be emptied first. Spray the pool tiles, where algae commonly grow, with the chlorine bleach. A little scrubbing will also help remove all traces of algae from the tiles.

Another way to use household bleach for killing pool algae would be to add it to the pool water. It generally takes 2 to 4 large containers of bleach to treat a normal-sized pool. The pump must be running continuously to make sure that all the algae are exposed to the chlorine.

Chlorine Shock Treatment

To effectively get rid of algae in the swimming pool, you can add high amounts of chlorine into the pool water. This process is called chlorine shock treatment. To make this treatment effective, the pool water must have a 7.0 pH level. Bring the pH level down by adding muriatic acid to the water.

The amount of chlorine needed for the shock treatment depends on the amount of water in the pool and the severity of the algae growth. 10,000 gallons of pool water needs a 1 pound bag of chlorine. Double the amount must if the algae growth is severe. The best time to do the shock treatment is at night. This is because chlorine gets damaged by sunlight and might lose its effectiveness in killing pool algae.

Shock treatments are also followed by the use of an algicide, which will prevent algae from returning to the water. "Green Clean" is an environmentally friendly algicide that is used in both swimming pools and fish ponds.

Skimming and Scrubbing

This home remedy requires more work and patience. Skim and scrub the pool at least once a day. Skimming the pool rids it of dead leaves and other debris that may sink to the bottom and rot. This will promote the growth of algae in the pool.

Regular scrubbing of the pool keeps the tiles clean and free from any algae. The algae will not have the chance to grow on the pool tiles if they are scrubbed down regularly. It may take a lot of work, but it is the safest alternative since it does not use any type of chemicals.
