Just want to verify how much pH will lower with CYA. I'm probably going to start with 10 CYA to test how fast we lose it because I still have one verified leak we aren't quite ready to fix until fall/winter at the earliest.
If it doesn't lose too much after a week we'll probably up the number up to the recommended 30. The pH is currently 7.6 with a TA of 80 and CH of 380 with TDS at 800..Total dissolved solids..not sure what that entails exactly, but I listed since its on the pool test I got from Leslies.
I know from prior reading that TA and pH are related in regards to acid changing pH...or at least thats the impression I got, but I'm not completely sure how much change to expect.
Thanks for any input on what I should do. pH is just about perfect where it is so if getting it to 10 and than 30 won't effect it that much I guess I can go ahead and leave not mess with the pH after adding the CYA. Considering the pH of the fill water when last tested was 8.0 it will likely trend up over time when we have to readd due to water evaporation...but the rate of loss is certainly less than before we fixed 2 other leaks so that'll probably be at least a month.
