I am in the process of closing my pool. My current chemical levels are as follows
FC 10
PH 7.4
TA 70
CH 280
CYA 70
22k gal, Bleach, Gunnite (pebble finish)
TA is a little low, but others are within acceptable operating range. I wanted to understand if the water temp should effect my approach to winterization. Under normal condition water temp 78-80 degrees the water has a CSI of -.26 When I lower the water temp to 56 degrees on the Pool Calculator the CSI drops further to -.46. Is this something to be concerned with during the winter months even though the water balance is with in operating levels? If so, should I raise the TA some and then raise PH to counter the water temp drop?
