Just closed/covered the pool for the off season. I run the SWG to maintain chlorine. Water temp never got lower than 53F last year and I expect pretty much the same this year. Chem levels are all pretty much in the ideal range right now except CSI. Should I do anything to raise CSI or just let it ride? It's only going to get more out of range as the water temp drops further. Here are the levels right now.
TC= 8.5
CC= 0
PH= 7.6
TA= 60
CH= 375
CYA= 80
SALT= 3200
CSI= -0.56
