Was a new convert at the end of last season, and just hoping to get guidance to start out right this year. Uncovered the pool, and filled the water on Sunday. Turned the filter on, did our first water test yesterday afternoon.
CYA=15? (husband did testing and said it may be a bit higher but gave me this number???)
My husband insisted we needed to shock, so he added 288 oz. bleach last night, to raise FC to 10, and ran pump all night.
Tested at 10:40 AM:
I know we need to lower total alkalinity. I don't have muriatic acid, but I do have some dry acid. It says add no more than 2 lbs. at a time. So do I gradually decrease pH to try to lower my TA?
