I am having trouble getting my pH back up here.
I just finished shocking my pool. I have a CYA of 30, TA of 120 (last check about 1 week ago). My FC is at 6 tonight.
2 nights ago I added three pounds of soda ash because my pH was at about 7.
It appeared to stay at 7 when I checked the next day so I added a full 4 lb box of borax.
Checked the pH today and it is at about 7.2.
I thought I would be at about 7.5 according to the pool calculator.
Any thoughts on why things are going up so slowly?
