Is yours from LA ir divers den?
And by far the best copper med i have used has been coppersafe. Much better than cupramine.
be very very careful with cupramine. It will burn the gills of most tangs without you even noticing. they will then start to spin in circles and die. I find coppersafe to be extremely successful against ICH in a small system (under 400 gallons). It is expensive compared to cupramine though, but for a QT the small bottles from pet co will work out fine.
I've never heard of Cupramine affecting tangs.
