here are today's test results with TF 100......
CYA 70 (measured yesterday, added necessary amount to sock in skimmer and ordering more cya reagent)
Water temp 82
Yesterday I added MA per the pool calculator because TA was 110 and PH was 7.8
I'm hoping I'm doing this right. I found this site last summer after pool was installed and have never even been in a pool store (thanks to the education and help here).
I added Borax last summer with good results (I thought as a complete newby) and want to again, but it seems that my TA and PH aren't perfect right now. Do I need to get these perfect before adding Borax and adjusting with MA?
