I have a Taylor K2006 test kit and their test and treatment guide has a Table N for cyanuric acid correction to total alkalinity.
See water test below.
FC 6.4
PH 7.6
TA 80
CH 260
CYA 40
I am in the lower acceptable range for TA at 80 ppm, however if I use their formula I am lower than the desired range. Carbonate alkalinity=TA-(CYA x .33) which equates to 80-(40 x .33). This puts me at 67 ppm. Does Troublefree pool use this table? This is new to me. Thanks for your help and sorry about the large image.
