10k gallon in ground pebbletec finish pool. I cant seem to get an accurate ph reading since installing the SWC. The taylor drop test kit has shows a 7.4 ph for the last 4 days. My PH is 7.4(taylor test kit) and the other (cheapy Pentair one builder gave me)says its 8.2(as high as it reads). My FC levels are 10. Pool water looks great. Should I drop in 2 cups of acid and see what happens? What should I do? Is it safe to run a higher PH with high FC levels?
