Testing Copper Wrong? Dosing Copper Aid and testing with a Hanna Copper checker.

[Egan126]

hello,
I Recently finished setting up my QT and added the amount of copper Aid to the tank per the bottle instructions. The bottle states to add 1 teaspoon per 4 Gallons. My QT is 40 gallons so I added 10 Teaspoons/50MLs. I then proceeded to test the water a day later with my Hanna copper checker and the test came out as 0.30ppm. Everything I have read this seems way under dosed but I double checked and I correctly dosed my QT per the bottles instructions. looking for some advice before I dose more or buy another form of test kit. any advice is greatly appreciated. PS treating for ich.

In straight terms, copper aid is complete garbage and is a herbal treatment and reason you getting the readings you see. You want coppersafe or copperpower which is industry safe chelated copper form

Adding to above when figuring out dosage make sure to account for any water displaced.

I’ve not used copper aid, but I know the chemist who developed it. He is usually pretty good at formulations.

It says it is chelated copper, and then does they give is suggestive of coppersafe, an amine chelated copper that usually tests at 2.25 ppm. However, the 0.60 reading you are getting is more in line with ionic copper (like Cupramine)

Does the bottle give instructions as to what the copper level should test at?
