Answers to Basic Pool Questions

Green Algae

What is it?

Common “green” algae are microscopic, aquatic plant-like organisms and can be free-floating or wall-clinging. Algae grows in salt or fresh water and thrives in temperatures above 30°C. In fact, it can “bloom” overnight. Algae spores constantly enter pool by rain, wind, animals, toys or swimsuits and left unchecked, can clog filters and create surface damage.
