CYA will not measure.

Taylor k-2006 Test kit- FC- 3.6 PH 7.0 TA-120 Can't get CYA to measure. Thoughts?

Sounds like there isn't any CYA in the pool. Or testing error.

The R-0013 reagent is fairly bullet-proof and almost never goes bad. Any CYA level less than 30ppm will result in a clear water sample when testing. You likely have less than 30ppm CYA.
