Newbie here. Does Ph ever stabilize? I have read about people with an SWG having trouble maintaining a consistent Ph, but what about those that do not have a SWG. I have a 20,000 gallon inground pool with a vinyl liner. My numbers are:

CYA - 45
TA - 90
CH - 120?
TC - 6.5
CC - 0
Ph - 7.4

I try to keep my clorine levels between 3-6 and I have to add about one 1.4Gallon jug every other day to do that. However, I am just curious if I should also be seeing my Ph drop on a regular basis. It seems like it drops about 0.4 every two weeks. I add Borax to get it back up, but I am just curious if that is normal.

Thanks.
