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.
