pH was 7.2 but after 2 days of swimming it's 8.0

Should I drop some acid or will it go back down on its own? I now have a Taylor fasdpd yest kit

Chlorine 7
pH 8.0
Alkalinity 120
Hardness 0
CYA 45

If you are adding chlorine with a SWG or bleach or liquid chlorine or cal hypo, you need to lower the PH with acid. If you are using trichlor tablets, they will lower the PH for you.

What he said, but you're already getting up there with the CYA. Personally, I'd just use muriatic acid to adjust pH. It will fix the pH with half an hour of pump running,

I use bleach for chlorine . My CYA was somewhere around 10-15, so I added 4 lbs of stabilizer which got it to 45. I'll add the acid. Thanks!
