After having extremely high CYA, we drained 2/3 of our pool and refilled with fresh water. Now working to get all chemicals balanced again. Took my sample to Leslie's after refilling. We use a Taylor test kit. But we do not have a test for high phosphates. Leslie's test showed 2,966 ppl...ideal range shows 0-100ppb. So...recommended to start with a clean filter, use 2 gallons, 12 oz. of Leslie's NoPhos, adding no more than 48 oz. at a time. Run the pump for 48 hours without backwashing or cleaning.Monitor filter pressure as it can rise rapidly with the use of NoPhos. After 48 hours of filtering clean or backwash the filter before adding any more NoPhos, which will need to be done in order to equal 2 gallons 12 ounces.
Hoping for advice from anyone who has dealt with this. It seems like a risky process. We have never tested for phosphates before and are wondering if the levels are dangerous or hurtful to our equipment. Just questioning the process. Any help is most appreciated.
