Seachem Cupramine and Hanna tester

[Alchameth]

So usually I'd do the 2 weeks and then GAC it out and do a water change, but because I've been hit twice I'm doing the 2 month med QT. So I have a 20G tank so with this it's pretty easy except I dosed for a 10G not 20G and did a water change. The Seachem tester is garbage trying to get that shade of blue to match so I got a Hanna Copper tester. Question is is .5 on the Hanna same as .5 on the Seachem tester?

Your Hanna should read .5 if dosing cupramine. I would not worry about the Seachem test kit. Hanna with make things a lot easier in testing the copper in the water.
