How do I test for phosphates? Why does PHOSfree raise my filter pressure? How can I ensure that after using PHOSfree that my phosphate levels come into acceptable range.

There are two options for testing phosphates: 1. Take a water sample into your local pool dealer and have them test your phosphates 2. Ask your local dealer for Natural Chemistry's 10 strips consumer phosphate test kit.

Important: Test for phosphates on an algae free pool for accurate readings. Chlorine must be below 5ppm or it could bleach the reagent in the test strips.

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.

A good rule of thumb is to keep an eye on the return valves (not only the filter gauge). If the water pressure from the returns is still good (even half the normal flow) then cleaning or backwashing the filter is not necessary. If the pressure from the returns is to the point where you can barely feel any water flow, then cleaning or backwashing the filter is necessary.

Note: Cleaning or backwashing the filter will remove the PHOSfree product, which means the product is no longer working and another application must be applied.

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.

For extremely high phosphate levels (over 1000ppb) we suggest using PHOSfree Commercial Strength. Phosphates need to be lowered to 100ppb or lower before beginning to use Pool Perfect+PHOSfree on a weekly basis.
