How To Treat Pool Algae

Algae can make a pool cloudy, clog filter systems and make pool surfaces slippery. The three most common colors of algae are green, black, and yellow (mustard). The best way to avoid an algae problem is to keep at least 1.0 ppm of free chlorine in pool water at all times. Constant filtration is also a must to prevent algae from growing (run filter at least 8 hours daily).
