Natural Chemistry PhosFree Commercial makes it easy to reduce phosphate levels. Formulated from lanthanum (rare earth compounds), it is a highly concentrated formula that quickly reduces very high phosphate levels. It is the only patented formula that removes phosphates from the filter.
With the circulation system operating: Maintain proper chemical levels. Backwash filter. Slowly add Phosfree Commercial AF directly to: pool, skimmer, gutter or surge tank. Backwash filter as necessary. Apply in accordance with your state and local pool regulation. Removing high phosphate levels may temporarily cause pool water cloudiness/turbidity. Retest phosphate levels after 48 hours.
Maintenance: Weekly, add 1 fl. oz (30ml) of Phosfree Commercial AF per 6,000 gallons of water. For best results and to reduce the possibility of cloudy water, use with an automatic dosage feeder.
