Copper Tester

[henryriesett]

Hello. I recently completed a cupramine copper treatment and have been trying to remove the copper. I use the seachem test kit, but was wondering the accuracy. Is it worth it to buy the hanna tester for copper? Also the seachem is super annoying to read. Anyone have insight to this?

From what I have heard, the Hanna copper tester is inaccurate in the low range.
