Your phosphate level should be at or below 100 parts per billion (ppb). If your water chemistry and phosphate levels seem to be in check, one potential cause of the cloudiness in your pool could be dead algae.

Algae are some of the most robust organisms on earth, able to grow in a wide range of conditions. Algae are usually found in damp places or bodies of water and thus are common in terrestrial as well as aquatic environments.However, terrestrial algae are usually rather inconspicuous and far more common in moist, tropical regions than dry ones, because algae lack vascular tissues and other adaptions to live on land.As mentioned above, algea grow in almost every habitat in every part of the world.owever, terrestrial algae are usually rather inconspicuous and far more common in moist, tropical regions than dry ones, because algae lack vascular tissues and other adaptions to live on land.
