Anyone have any thoughts on PH levels in winter time? I have an intellichem on my pool. All of my levels are in range. However, with the water temp in the high 30's, I would need to have my PH somewhere around 8 to be at an ideal level on the CSI index. At 7.5 PH, the intellichem is reporting that my water is corrosive.
Anyone have any thoughts on this?
