Hey watermom, yes, I did order the Taylor K-2006 typo. So I just got it and ran the CYA test. I was surprised to have it read 30-40ppm when my pool store reading was 80 ppm. I'm thinking I should run another test but before I do, what is your experience with the rate of Chlorine depletion/vs the level of CYA? I'm losing about 4-5ppm of chlorine daily but nothing over night. Does that give any indication as to which CYA reading makes more sense?
