NFG react with hanna copper test?

Does NFG react with the Hana copper checker? Will it Skew my results?

I dont really know the answer, but I suspect it will interfere. NfG stains the water pretty heavy and I think that would throw off the checker.

I do know that although you can mix nfg and.copper, I do not do that. The nfg is less effective in copper and harder on fish when mixed with copper. If I need antibiotics in copper, I prefer spectogram.
