CYA creeping up when only using bleach

[SafetyBob]

Carl, I don't know if I am wasting money or not, but I have started replacing all my chemicals on my Taylor 2006C test kit for just the reasons you point out above. I don't have a lab here at the house to test my supplies to ensure they will give me accurate results. Since it is not "that" much to do it, I replaced them all. Testing accurately did so much to enhance my pool experience last year, I cannot feel good about operating the pool unless I KNOW my chemistry is fresh and right on.

Sounds like a plan!

You can also buy standard solutions from Taylor to verify your testing results and reagents. If you are getting that much discrepancy in the CYHa test you might want to invest in a bottle of CYA standard solution.
