Natural Chemistry 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. PHOSfree will not cloud pool water. Natural Chemistry's complete phosphate program results in clear perfect water, no waterline rings, no unpleasant odors, and no phosphates.PHOSfree may raise the filter pressure as it puts a coating on the filter media so it is able to catch the phosphates. After 48 hours or filter running time, the filter should be cleaned or backwashed to remove the used PHOSfree as well as the phosphates. We recommend adding small doses of PHOSfree per application to prevent clogging of the filter. Do not add more than 1L (32oz) at a time per every 48 hour application. Cleaning or backwashing the filter will remove the PHOSfree product, which means the product is no longer working and another application must be applied.
