Tips & Info
Always test your phosphate level before using Phos Free, it is the only way to know your required dosage and if you are making progress in the phosphate removal process. Take a water sample into your local pool dealer and have them test your phosphates.

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. Algae must be treated first, prior to testing or lowering phosphates. Chlorine must be under 5ppm before testing phosphates

Phos Free is not affected by high levels of sanitizer.
