While algae creates problems in swimming pools, they are one of the most important organisms on earth, capturing more of the sun’s energy through photosynthesis than all other plants combined.
Algae problems come because of extreme weather conditions and/or chemical imbalances in your pool. Excessive heat, wind and dust promote algae growth. If your water chemistry is off, then you are destined for an algae bloom. Algae grows best in indirect sunlight and in “dead zone” areas where circulation is poor. Rough or etched surfaces are ideal for algae growth, so it can “dig in” and firmly attach itself to the surface.
