Phos Free 2L
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.
Most effective way to remove phosphates prior to using a weekly maintenance product
Works in the filter (no clouding of the pool water)
