Natural Chemistry - PHOSfree Phosphate Remover

Natural Chemistry PHOSfree is formulated from lanthanum (rare earth) compounds. When added to your skimmer, a thin coating of PHOSfree forms on the filter media. As pool water flows through the filter, phosphates are reduced to very low levels due to the lathanum and phosphate molecules sticking together. Works inside the filter which means no clouding of the water.

For DE & Cartridge Filters: Do not add more than 1.5L (48oz) at a time. If more than 1.5L (48oz) is needed to treat, be sure to clean or backwash the filter between treatments.

Please Note: Algae must be treated prior to testing and lowering phosphates. Chlorine must be under 5ppm before testing phosphates.
