Fc up to 7.2 and ph down slightly to 7.2 (as a result of the cya I assume) will wait a few days to test cya level but added a bit more today and my best guess is that I should be around 45 after all is said and done. Chlorine held well added last night and while today was mostly cloudy it seems as if the chlorine is beginning to hold. Will add some borax tomorrow to keep ph in the 7.6 region. Looks like I may be swimming this weekend!
