New pool here and getting close to closing. Still waiting for safety cover to be delivered and we’ve had a couple of “warm” days so the kids were able to swim still for a bit. That being said I’ve been keeping my water chemistry in check but over the last 2-3 weeks my FC has gone up quite a bit. Probably because of less swimming and less sun (backyard has a lot of shade now from the angle of the sun this time of year). Water temp hovers mid 70s even with heater off.
Today’s test shows pH 7.8, FC 10.5, TA 90. I didn’t test CYA because I’m out of reagent and I figured it doesn’t matter because my FC is up quite a bit. For comparison 2 weeks ago FC was 5, then 7 last week. Should I dial back SWCG to allow FC to gradually drop or should I just aim to maintain it relatively higher knowing I’ll need to add shock anyway at closing and thereby need less shock?
