Inst there a mathematical formula to calculate it? I'm primarily worried about chlorine and I don't fully understand Ben's best guess chart. I know I have to CYA first to find out where its at and then gage the FC to that. Why am I testing for FC and CC to add them up and get TC when the best guess chart is for FC? Why not just test for FC only?
