I had used Trichlor for many, many years. I discovered the BBB method in March. The CYA had been running around 90. The pH had been stable since I began testing with the TF 100 kit. Chlorine jumped around. I use the pool very little, have never had a CC reading register. June 8 my readings were TC 7, pH 7.6, TA 160, CYA 90. I drained water from the pool today and after refilling, the readings are TC 7 pH 7.2, TA 130, CYA 65. I'm ready to work on the TA. Should I wait a few days to see how the pH fares, or should get it down to 7.0? I have a lot of aeration built into my pool.
