My pH was 7.5-7.8 this Saturday when I tested. I just tested it 30 mins ago and it appears to be 8 or maybe 8.2 (these color comparisons kill me)
My pool has a built in spa that overflows so I imagine that's doing aeration.
I would think it would be ideal to try and keep the pH steady, so I need to adjust daily? Weekly?
Good news is my FC seemed to test around 5 (again hard to tell, wasn't using FAS-DPD)... last I tested it was 1-2 but I've also bumped the CYA up.
