Accuracy of the Hanna Checker for ammonia while dosing copper?

Frogspon · Feb 20, 2021

I know Seachem's badges/tests are recommended while QT with copper.. are there any other brands that you can cross check with?

Having trouble finding a lot of info on tests that are not affected by copper.

Does the Hanna checker for ammonia do well with copper?

No, I do not think copper will interfere with the Hanna ammonia test kit since it uses the Nessler method and employs EDTA to maintain solubility of magnesium and calcium (see attached instructions). EDTA will also bind trace copper and prevent interference.
