Went to the pool store today.

CYA: 70
TC: 3
FC: 3
pH: 7.6
TA: 145
ATA: 124
Hardness: 200

We are continuing to put in 1.5-2.5 gallons of chlorine every day. Last night we did 3 and it's already down to a 3. So much chlorine! The pool does seem to be very slowly clearing up but still haven't seen the bottom. I was thinking to add another 3 gallons and then wondering about the pH. Is it getting too high?
