I am...befuddled, to put it mildly. My pH has dropped from 8.2 on Sunday to 7.2 today, with only the addition of bleach. If you'll recall, when I opened the pool on Satuday, the pH was 7.5. My FC had dropped to 7.5, so I added my first dose of dichlor this evening. CC was 2.5. The good news is that I seem to have gotten rid of most organic matter off the bottom. My water is cloudy blue.

Any thoughts on the pH yo-yo?
