Product Details

PHOS Free - 2 Liter - by Natural Chemistry

Description: This patented formula will remove damaging phosphate build up that is in any swimming pool filter and in the pool water.

Function: Phosphates are inorganic chemicals that typically enter swimming pools through regular city water lines, rain, plant waste, fertilizers, lawn run-off and even tanning oils. Phosphates are the building blocks for algae, so increased levels of these chemicals can transform any above ground swimming pool into an above ground pond filled with green organics. Use PHOS Free by Natural Chemistry to remove unwanted phosphates from your filters!
