Phosphate Remover

Also Known As:

Phosphates are compounds containing phosphorous. In water, these are broken down into orthophosphates via one of three ways: oxidation, hydrolysis and enzymatic digestion. In pool water, the method is typically hydrolysis, although oxidation may play a supporting role.

Phosphates can be introduced into pool water iin a variety of ways, including landscaping fertilizers, rainwater, shampoos and soaps, and even pool chemicals and tile cleaners.

When phosphate levels are too high in a swimming pool, a number of problems can occur. First, algae may be encouraged to grow and bloom. That’s because phosphates are plant food. When algae have access to a buffet of phosphates, it will eat and grow. On the other hand, when algae are deprived of food, it cannot survive.

Calcium phosphate scale is another issue that can arise when phosphate levels are too high. A cousin of calcium scale, this often forms in warmer water and falls out of solution. In these favorable conditions, phosphate fuses with calcium to form a gritty, sand-like scale, which collects on pool surfaces and equipment. Predictably, this can wreck havoc on salt generator cells and heat exchangers. Because of its appearance and feel, calcium phosphate scale might be mistaken for a grid issue in a DE filter. Reducing phosphate levels in pool water prevents this scale from forming.

Clearly, it’s important to remove phosphates from pool water. And this is done with a phosphate remover, which bonds to the phosphates, making the particles larger, and can either be filtered through the pool’s system or vacuumed from the bottom of the pool.

Before using a phosphate remover, check the water’s phosphate levels. Then follow the manufacturer’s instructions carefully. After using the product, check the water’s phosphate levels again. Following a phosphate removal treatment, the water may look milky, but this is temporary.
