Leslie's NoPHOS 3L Bottle removes phosphates from your pool water, giving you crystal clear water without leaving waterline rings or producing strange odors. Product packaging may vary, with no change to product composition or weight.
  • Phosphate Remover
  • 20% Stronger than regular PHOSfree
  • Easily added to skimmer
  • Does not cloud water
  • Clears up water
  • Does not leave rings
  • No odor
  • Improves efficiency
  • Mineral based

NoPHOS is formulated from lanthanum (rare earth) compounds. When added to your skimmer, a thin coating of NoPHOS 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! This extra strength formula is 20% stronger than traditional PHOSfree. Leslie's complete phosphate program results in clear perfect water, no waterline rings, no unpleasant odors, and no phosphates.

Dosage: 4 oz per 8,000 gallons.
