Phos Free Commercial Strength Phosphate Remover for Pools
Phosphates commonly accumulate in swimming pool water through the addition of rainwater and swimmer waste. Unfortunately, phosphates are one of the main food sources for algae. As a result, when swimming pool phosphate levels rise so does the likelihood of algae growth.  Phos Free is a non-toxic, natural mineral product which quickly and effectively eliminates phosphates from pool water, starving and killing algae. Phos Free for swimming pools is ideal for even the most stubborn algae blooms and is completely safe to use.
