CAUSES: There are many contributing factors that can lead to algae, but the most significant is not having enough sanitizer (chlorine), coupled with poor water circulation. Below is a short list of the most common influencing factors that allow algae spores to grow:
Pool is not shocked recently leading to too many chloramines
Pump and filter are not running long enough
Not enough stabilizer creating a low chlorine level
Not enough chlorine
Improper pH & total alkalinity
Too much phosphate in the water
Pool finish that is very porous
SOLUTIONS:
- Test water and balance pH and total alkalinity if necessary.

| MUSTARD |
Description
Yellow or Mustard algae is a common type of algae, especially in the south. It comes in varied degrees of severity, but most often is seen as patches of dark yellow dust that covers various parts of the pool walls and floors. It usually starts in corners of the pool, near the steps, by the ladder, and other areas where the water circulation is not good. Unless the algae gets into cracks, pits or crevices of the pool surface, mustard algae will brush off easily.

| GREEN |
Description
Green algae is a normal type of algae found in swimming pools. Its severity can be as minor as a green tint to the color of your water, or as harsh as dark green fuzzy growths all over the walls and floor - the water tint being so dark that you cannot see the bottom of your pool.

| BLACK |
Description
Black algae is not the most common, but unfortunately is the most difficult type of algae to remove. Its severity can vary most difficult type of algae to remove. Its severity can vary from as minor as a few small black spots, to entirely covering the pool's surface. Black algae usually grows in clusters creating large blotchy areas of black. Black algae is difficult to kill because its roots grow deep into the pool's surface and black algae has a tough outer coating, like the shell of a turtle, which makes it difficult for chemicals to attack.
