Ammonia and Copper Power

[DexterKarin]

Newish person here. If my badge reads 0 ammonia and copper 2.36 ppm (Hanna), I'm okay vis a vis ammonia because the error that has been noted is in the other direction, reading too high of ammonia. Correct? Fish looks good btw.

I’ve heard that ammonia badges don’t read the 0.50 ppm ammonia bound up in coppersafe/ copper power. I haven’t tested that myself though. The salicylate ammonia test does register that bound ammonia though.
