All that I've been reading in the Pool School suggests that high chlorine levels can create false high pH levels. My FC is 20 (CC - 0), and my pH is reading 7.6, which doesn't seem "high" to me. Does pH always read high when chlorine levels are where mine are? If so, should I assume I actually have pH that could be too low, and therefore reducing the efficacy of my sanitizer? (My pH was 7.2 before I shocked).
Thanks in advance. Everyone here has been so helpful!
