Hi, I have a Softub 140 and follow the dichlor bleach method. A week ago I did a fresh fill to prepare through winter, my municipal water is really good. Got CH to 140 then started messing with PH and TA. My TA was 70 but PH was high, I aerated and it went above 8 so according to the method, I needed to decrease TA. I got some muriatic acid and used the pool calculator to start lowering. I kept aerating and checked every 30 min or so. Once I finally got PH a little more stable my TA was 40! What do you do when TA is low but PH was drifting still? I checked both today after letting it rest 24 hours and PH was 7.4 I added baking soda to get TA back up, have not checked PH drift again.
I don't really understand the aerating PH drift. Does it do it everytime you aerate or does it eventually stabilize? When you're done aerating does it go back down or stay high?
Thanks for the help!
