Natural Chemistry Phos Free
Most effective way to remove phosphates.
Reducing phosphate levels in pools is easy with Natural Chemistry’s patented Phosfree technology. Phosfree is formulated from lanthanum (rare earth) compounds. When added to the skimmer, a thin coating of Phosfree forms on the filter media. As pool water flows through the filter, phosphates are reduced to a very low level.
