copper effects?

[twistedspectrum]

So I've got a disease in my tank. It's either ich or velvet; I can't exactly determine which, so I was planning on catching and quarantining all of my fish and dosing them with copper; then allowing my tank to sit fallow for about six weeks to allow for any ich to die off.

Since I'm relatively new to the hobby, however, I want to make sure that my fish can withstand a copper treatment and that none of them are going to be overly harmed because of it. I have no plans on breeding, so that isn't an issue.

Currenlty in the tank:
2 bangaii cardinals
1 bi-colored blenny
2 orange clownfish
1 yellow tang
1 dwarf golden moray eel
1 flame hawkfish
1 six-line wrasse
2 golden-headed sleeper gobi
1 mandarin gobi
1 niger trigger
2 blue damsels
1 yellow-spotted puffer (who is a brackish fish that has been acclimated to saltwater)

Any information would be helpful.

Here is some good info on cupramine which is the copper most on here use.

Also if you are going to all this trouble I would wait an extra 2 weeks for a total of 8 weeks fallow. If u put them back too soon u will have wasted your time and the treatment.
