Hello everyone. It's been cold here in FL and we've had a lot of rain and storms lately. Since last week, I got 2-3" of rainwater into the pool. My CH has dropped down to 220. My readings today:
FC - 9
PH - 7.7
TA - 70
CH - 220
That seems to be under the 250-350 range for a plaster bleach pool. Should I bring that up and if so, use just calcium chloride or that plus baking soda?
