What Is Algae?

Algae is the most common fouler of pools. When pool owners panic and run screaming to a pool pro for help, algae is most frequently the cause. That’s why we call it one of the best salesmen. You must deal with an algaecide. Actually, in addition to getting rid of algae, one of the most effective uses of algaecide is to extend the effectiveness of chlorine residual. While chlorine is an algaecide, it’s wise to add additional quantities as a backup, a maintenance dose.

What is algae?

Algae are small plants that propagate by air-borne spores. They enter swimming pools and quickly turn the water green. When conditions favor their growth, they can cause black and/or green spots on pool walls. Heavy rain, intense sunlight, and presence of nitrogenous material all contribute to algae bloom – as the rapid growth of algae is called. Sometimes algae bloom results in a sharp rise in pH, as the algae consume carbon dioxide in the pool water. If algae bloom is present, super chlorination should be used. Then an algaecide will control it, and prevent its reoccurrence. The best insurance against algae? Maintain a free chlorine residual in the pool at all times. An effective way to do this is to sanitize with stabilized pool chlorinating concentrates, and add algaecide according to the directions on the label.
