I believe our pool is 36x18 in ground. We pulled the cover off last week to green city. So we entered slam mode with liquid chlorine . After a few days it started to clear up but kinda stalled . Used our Taylor test kit and checked the PH and it was way above 8 . Gave it 5-6 cups of acid over four days and it started getting clearer . Alkalinity is good and got the PH down to 7.8. When I check it in the morning it keeps raising back to 8 or a little over. Could this be the amount of liquid chlorine raising it and when the chlorine dies off it comes back down? I plan on doing a full test this afternoon and posting results. I know our CYA isnt high at all , if anything it’s possible too low. If anything immediate comes to mind please chime in but I will have results of a full test a little later. Thanks .
PH keeps going up after lowering it

There is no need to test pH during slam. The high FC also interferes with the pH test, giving a false high result. Carry on, don’t add more acid. Test pH after slam when FC is below 10.
