Hello all. Glad to be back here and I see the forum is buzzing!
Overall I have had a pretty uneventful opening this season since closing the pool last season according to the advice given here. But have a few questions regarding my opening test results. The water was a tad cloudy right after opening but after topping off, adjusting FC, pH, TA, brushing and running the filter for a few hours the clarity and sparkle was back.
Closing tests results: Early November
(taken prior to raising to shock level)
Opening test results: Mid May
The water was not circulated prior to testing but I did brush a bit. Is the drop in CH, CYA and Borate expected in a covered pool over about 7 months?
