Quarantine Method

Hi all,

I'm getting near to my first fish purchase.

I've gone cross-eyed trying to review a suitable quarantine method. Tank transfer method vs. copper vs. observe then treat if only needed. Also, Copper powder, coppersafe, vs cupramine. What have you had the most success? Prazi seems to be the other consistent usage across all of the methods. I have plenty of tanks for the ttm. (I'm a long time freshwater guy.) I also have cupramine and copper powder on hand along with a Hanna copper checker.

I would start by treating the fish whether or not you see a disease. Take Ich for example... the fish my have a few parasites, but be healthy enough to not show signs of it at all. Then you bring in another fish later where you had to treat it for something only for it to break out with Ich as soon as it goes into the tank.

Since you already have copper and a checker, I would probably start with it for the fish that can handle copper. Not sure which is best but @Reefahholic is using Copper Powder from what I've seen in his videos.

For fish that you can't treat with copper, TTM may be the only option. Although if you are treating for Ich it's a 72 hour transfer, but Velvet is a 18 hour transfer.

I would also suggest a FW dip for the fish to reduce the parasites to give the fish a better fighting chance while you are treating it.

I also have been advised to use the "triple threat" / "trifecta" of metroplex, kanaplex, and furan-2 (and binding with Seachem Focus). I think AquaZoo off El Dorado sells all of them if you need it in a hurry.
