What chemical helps prevent algae growth in pools?

Algaecide is specifically formulated to target and prevent the growth of algae in pool water. It contains active ingredients that inhibit the development of algae, making it an essential chemical for maintaining a clear and clean pool environment. While chlorine and bromine are effective sanitizers that help in killing bacteria and controlling other microorganisms, their primary function is not specifically geared towards algae prevention. Flocculants serve a different role by clumping together particles in the water, making them easier to filter out, but they do not actively prevent algae growth. Therefore, the use of algaecide is the most effective means of directly combating algae in pools, ensuring that the water remains clear and enjoyable for swimming.
