Re: Does shocking w/12.5% raise CYA? Help!
I know the pH reading is bogus because of the interferance from your high chlorine levels. I suspect the CYA reading might be suffereing from interferance aslo. Not quite sure how they test for cya with the strips but I know it is not the same chemisty as the reagent test uses. Just one more reason to avoid test strips and get a drop based test kit. Wait until your chlorine levels drop to normal and then retest.
