I use my well to fill and top off my pool. Our ground water here is very hard and alkaline. The wells numbers are:
My pool numbers are currently:
CL 1 ppm
FC ??? (new reagents on the way)
CYA much less than 30.
I added about 20" of water last week to get the level up into the skimmer. At that time the pH was about 6.2 but within a week has moved to 7.8. Did I see a rapid change because my TA is high? With fill water at TA 430 and I always going to be fighting to keep the TA lower?
I've always used OTO test kits before and have never attempted to keep everything balance. I have a fiberglass pool and I don't know how much I should worry about the CH. Any advice would be much appreciated.
