I still have my winter mesh cover on & will until end of May but I test & dose the pool anyways & hand brush for circulation all winter

CH 260 Target 375 with 257 oz by volume of calcium chloride shy at 243
CSI: balanced
3.28.2020
pH 7.5
FC 7
CC
TA 50
CH 220-230
CYA 0 Target 20 so 55oz by Volume + add 3 more pucks
65° F and should be warming
CSI: potential plaster corrosion until increase pH to 7.8
I can increase pH to 7.8 ; but in all my years I never saw my pH go down (been at 7.7+ all winter, where I like it) so I wanted to ask to get your opinions before I raise the pH. In past summers/warm water/open pool it's best with TA 50 & CH 300 (In winter it's best at TA60-70 & CH 400).
We've had a ton of rain this winter but normal amounts since the last test 8 day ago.
I should get the pH up to 7.8, right? Want me to bump the CH to 300?
Just kind of weird about the pH dropping for the 1st time ever (yes the reagents are fresh) but my plaster is in very poor shape. Thank you.
