I finally just opened my pool for the season. I haven't done all not remeasurements yet, but estimated CYA based on what I had last year and the water added (from 50 to 37 with 25% water added). I raised the FC to shock level (15), and will monitor overnight. However, I too noticed that my TA was high at 130, and my pre-shock PH was 7.2. I started aerating as best I can by pointing the jet upward. However, I recall reading last year that PH readings are not accurate with high FC levels; how do I proceed if this is the case?
I'll also add that I just added a heater, and I am kind of freaked out about maintaining proper PH levels for the sake of the life of the metal. Any reasurring or corrective words that can guide me?
