I use both products exclusively in my quarantine protocol, although not usually at the same time.

I typically take twice the time the bottle recommends to get to the active dose of cupramine.

Are you certain you have flukes? You may be able to get out of it, or at least provide some immediate relief with freshwater dips.

The tang may struggle with cupramine, I would not take it to the full dose on the bottle, typically a final dose of 0.4 has been sufficient for me in the past.
