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. All other phosphate products will cloud pool water! Natural Chemistry's complete phosphate program results in clear perfect water, no waterline rings, no unpleasant odors, and no phosphates.
- Most effective formulation available
- Works in the filter (no clouding of the pool water)
- Reduces phosphates down to near zero
- Reduces pool maintenance
- No Phosphates - No Problems
Directions for use:- If pool has algae, follow dealer instructions to treat.
- Follow dealer instructions to balance water chemically.
- Clean or backwash filter, if necessary.
- Determine required Phosfree dosage from chart.
- With filter running, shake bottle well, and add required dose directly to skimmer. If D.E. filter pressure rises above normal range, bump filter per manufacturers instructions and restart. Repeat until pressure stays in normal range.
- Run filter 8 hours/day for one week or 48 hours continuously without backwashing or cleaning. When phosphate levels are 100 ppb or less begin maintenance with weekly dose of Pool Perfect + Phosfree.
