Quick Copper Qeustion

[Punchanello]

My copper in qt (10 gallon) was reading .44. I added two drops of cupramine (approx .1ml) and am now reading .77. Does that math stack up or am I getting a faulty reading? Using Hanna copper hr

Thanks, my mathematics are terrible.

Faulty reading for sure. 2 drops of cupramine in 10g is about .025. You have to clean the test vial really well when using hanna checker to get a correct result.
