FC - 7.0
pH - 7.8
TA - 120
Borate - 50
My TA was down around 60, so I added 8 lb of baking soda, yesterday.
I waited 3 or 4 hours and it read 130.
My pH was up around 8.0 so I added 1 qt +3 oz. of muriatic acid. That was 1/2 of what the pool calculator gave to lower pH to 7.2.
Checked it about an hour later. pH read 7.7 (Guessing at colors), so I added the other quart of acid.
That was about 2 hours before I turned the pump off.
I ran it about an hour this morning and pH still reads 7.7 or 7.8.
I hate to keep pouring acid into what looks like illogical readings. Should I hit it with another quart or wait awhile and check it?
