Can you swim in a pool with high phosphates?

At low levels, phosphates in a swimming pool don’t affect the quality of water. In fact, some levels might actually improve the quality of pool water. On the other hand, high phosphate levels promote algae growth and use up chlorine rapidly, so it’s very important to keep track of phosphate balance.

Phosphates in Swimming Pools - How to use Phosphate removers

What are Phosphates and Phosphate Removers?

Phosphates are organic compounds derived from phosphoric acid. Phosphates come from a plethora of sources, from sweat to soap to leaves.

With relation to your pool (or spa) experience, phosphates can be thought of like a buffet of food for algae and can allow them to grow uncontrollably if not treated appropriately. Lowering phosphates can be thought of as an insurance policy if chlorine is allowed to dip below the recommended levels.

Phosphate removers use lanthanum, a rare earth metal, to bind and remove phosphates and allow them to be filtered out of water. David over at the Pool Guy podcast has a great podcast on when to actually use phosphates.

What Form(s) Does Phosphate Remover Come In And How Do I Use It?

Phosphate remover comes in liquid form, typically in gallon jugs or 32 oz. bottles, and should be poured according to manufacturer instructions.
