Becca1984 Posted April 23, 2022 Report Share Posted April 23, 2022 We moved into a new house and are first time pool owners. We noticed right off the bat that chlorine levels were so low we couldn't get them to register on test strips. After the bitter winter, we took our water in to a pool store and got it tested. All the levels were a mess but the big concern was CYA (150s). We drained the pool 1/3 and had it retested. CYA went down slightly but was still over 100 (130s). We drained again and retested. CYA was even higher (back in the 150s). We used test strips to confirm high CYA. We are at a loss. Do we drain for a 3rd time?? All other levels are good except slightly high alkalinity (per test strips). Also should add we are on well water. Quote Link to comment Share on other sites More sharing options...
