PR-10,000 Phosphate Remover Concentrate

PR-10,000 is the strongest, most concentrated phosphate control product available in the aquatics market. It is formulated to react with phosphates in water, allowing for them to be removed from solution. It is an all-natural, rare earth phosphate removal product. It reacts with orthophosphates on contact, crystalizing them. The inert phosphates then sink out of solution to be vacuumed or filtered out. PR-10,000 causes cloudiness in the water for up to two days. Use only as needed.

Because of its concentration, a little goes a long way. A dose of PR-10,000 may be surprisingly small to you, but watch it work.


8 ounces can remove up to 2500 parts-per-billion of orthophosphates in 10,000 gallons of water. We recommend not exceeding 8oz/10,000 gallons for a normal treatment unless otherwise specified.

For pools with algae: We recommend using PR-10,000 immediately following a chlorine shock. Use 16oz/10,000 gallons for light algae, and a full purge dose of 32oz/10,000 gallons if the algae is severe. The next day, clean the pool and vacuum the dead algae and phosphate precipitate, and purge with CV-600 enzymes.

PR-10,000 is NSF/ANSI Certified standard 50.
