PH keeps rising

[Chief2505]

Todays test results

FC/TC 4.5-4.5
PH 7.8 - 8.0 hard for me to decipher the color differences
ALK 60
CH 150
Salt 3400, SWG is set at 60% and runs with my pump 12 hours a day

CYA on 7/7/2024 was 60, I have not tested since then

7/4/2024 my PH was 8.0 or higher and I added a gallon of acid, by 7/5/2024 test PH was 7.0 -7.2.
I test PH, FC/TC and ALK daily and my PH rises every day a little bit.

Am I missing something? Or do I just have one of those pools that loves to eat acid?

All of our pools like acid, the key is to minimize its rise. I'm assuming your plaster is well cured, so that sholdn't be an issue. Do you have any forms of aeration (waterfall, spill-over, bubblers, etc)?

Strike that, I see you have a vinyl pool, so that eliminates that totally.

7/4/2024 my PH was 8.0 or higher and I added a gallon of acid, by 7/5/2024 test PH was 7.0 -7.2.

High TA and low pH causes pH rise.

Stop forcing pH down to 7.0/7.2.

With TA of 60, your pH should be fairly stable between 7.8 and 8.0. Running your pool with a pH of 7.8 to 8.0 is just fine.

I finally received my water bill from filling the pool and I only used 29,100 gallons of water that month, minus the 1,000 that we normally consume means my pool does not hold near as much water as I had been told and previously calculated. I guess those 4' radius corners and the sloping in of the sides in the deep end reduce the volume by far more than I had imagined! Now off to update my profile!
