When to use Algaecides
Algaecides are used to prevent algae growth and kill existing algae that survive general chlorine
dosages. Algae is an aquatic plant that grows rapidly in pool water when a combination of warm
water and lack of chlorine or other sanitizing agents exist. The most common types of pool water
algae are green, pink, black and mustard. Initial signs of algae growth are slipperiness on pool
surface, green or cloudy water and spots on pool walls or floor.
