I recently had my pool replastered so it is taking a lot of acid. Daily doses, knock it down to 7.2 in the morning and it's back to 7.8 or 8.0 in the evening. I'm working my TA down some more to see if that will help. The question I have is, will a high PH for a week hurt much, start scaling, etc or am I good for that amount of time and shouldn't worry about it.
Numbers since everyone asks.
Chlorine - 7.0
TA - 70
CYA - 50
PH 7.2 to 7.8 depending on the day. Right now 7.4
CH - 300
Salt - added for feel and overshot - 2800 (kids loved it)
I use a peristaltic pump to add bleach nightly.
