Using Pool Math I noticed that water becomes more corrosive as it gets colder and pH and TA have the biggest impact on CSI. My readings (using 30 degrees for a winter water temp) are as follows:
FC 15
CC 0
pH 7.7
TA 80
CH 220
CYA 40
CSI -.47
If I raise pH to 7.8 and TA to 90 I get a CSI of -.31 ( a bit better). I don't have any calcium chloride on hand and that has a minimal impact on CSI anyway. Should I raise pH and TA to these levels or is everything okay as is? Thanks.
