In the simplest way here is the information you need to know about phosphates.

Phosphates are vital plant nutrient that help increase plant growth rates.  Algae are in the plant family.  Therefore, if phosphates are in the swimming pool water and there is a trace of algae in the swimming pool, then the phosphates will help the algae grow at an accelerated rate.

1.      How do I get phosphates in my pool water??

The challenge with phosphates is that they are constantly being introduced into your swimming pool water. Phosphates are found in lawn and garden fertilizers, decaying vegetation, municipal water, cosmetic items on bathers, and even other pool chemicals.

This means that phosphates can enter your pool water through many different avenues. For example: the wind blows dirt, leaves, twigs, or bark into your pool, the sprinkler run off from your lawn or landscaping enters your pool, you put fresh water into your pool or you have heavy pool use with lots of skin products.

2.      How do I know if my pool has phosphates?

Pure Water Pools of Naples has to perform a special water test on your pool to see if phosphates are present and to what extent. This test is outside of our normally weekly maintenance plans.

If we determine that the levels are about the recommended guidelines, we will suggest a phosphate removal treatment plan.

3.      How do I remove phosphates?

It is possible to remove modest levels of phosphates, by treating the pool water with a phosphate eliminating product.  Phosphate treatments typically take two to three trips by a knowledgeable technician.

The first step is to add a phosphate removal product to the pool water.  We leave the filter system to circulate for 24 hours. Then, the technician comes back, brushes the pool, cleans the filter system and tests the water again to see if the levels have been lowered to an acceptable level. If not, we will repeat the process until the phosphates are at an acceptable level.
