I can't seem to keep my PH at 7.6; it always goes down to 7.2
Numbers as of this evening:
FC: 3.5 (a bit low I know, I ran out of CL and haven't had a chance to get more - it was at 7 on Saturday)
PH: 7.4 - 7.2
This past weekend I raised by PH using borax to get it to 7.6 on Friday and again on Sunday (it dropped back to 7.2 on Sat). This also raised TA from 60 to 70 and on Sunday I raised TA further to 80. Today it measured 7.4 - 7.2; not quite either color just right in between.
My wife and daughter are complaining that the pool water is stinging their eyes at 7.2. The FC was at 7 that day but that's in the range for a CYA of 60 (rec FC 5-9).
Should I raise my TA more?
