Odd Color Change when Testing for Chlorine

[RudyandRocky]

I bought new reagents and my chlorine readings are much higher and it doesn't turn the funny color. Interesting, because the reagants weren't very old.

Anyways.............now I know what to look for.

Thanks!

DPD reagent #2 does have a shorter shelf life than the rest of the reagents in the test.
