Natural Chemistry PHOSfree Directions for Use

PHOSfree is designed to remove phosphates through filtration by applying a coating to the filter media. Depending on the phosphate level, more than one dose may be required. Important: Do not add more than 1L (32oz) within a 48 hour period. Phosphates need to be lowered to 100ppb or lower before beginning to use Pool Perfect+PHOSfree on a weekly basis.
