I have been using the BBB method for several weeks now and that, coupled with this site, have given me clear pool water for the first time in a long time. I have to remember to take a photo to post soon Anyway, I have high CYA levels (even after draining the pool to 80% twice) so my results are:
FC = 16
CC = 0
PH = 7.2
CH = 400
TA = 100
CYA = 90
I have read in several places on this board that if the FC level is high, then PH readings will be inaccurate. My PH level has held steady at 7.2 for over a week once I was done shocking with liquid chlorine and let the FC level fall to target based on my CYA.
Should I be concerned that my PH is testing at 7.2 with the FC level I have?
