Ich help/question

[wooden_reefer]

My LFS told me that if I treat any fish with copper in a QT tank that the copper on the fishes skin will leach into the main display tank and kill my corals. I don't believe this for a second, but I was planning on QTing all my fish for at least two weeks before letting them enter my system.

The copper in the WATER will deposit on calcareous materials, such as corals and live rock. I believe the deposit is copper carbonate, but precisely what it is likely doesn't matter much.

Will the deposit leech out? I think it will not unless the ph changes significantly. Many people think otherwise. If you put all the copper treated LR in the sump, and you remember which LR, would it still cause problems? I don't know.

Will many inverts' direct contact with copper carbonate harm them? This is also a consideration. I also don't know.

I know that the prevailing thought is that copper depoist on LR is not a good idea. I don't know enough to refute or affirm this thought.

I'd avoid using copper in DT intended later for inverts, except shrimps and crabs.

E.IntheC, hey buddy I just wanted to tell you that over the last year I have had several fish come up with Ich and most of them continued to eat, so I thought I will leave him and see how he does because he is still eating. Well, everyone of them died. I now quarantine any new fish I get and currently have a yellow eyed tang in QT and he has been there for 2 weeks, eating strong looking great. I woke up this morning to him absolutely covered in ich, so I am going to treat him with copper. This will be my first copper treatment so I hope it goes well but since I have never had a fish survive after getting ich (and there have been quite a few) I am gonna treat this one. Plus I am going to look into the uv light because a buddy of mine said he put one on his DT and he hasn't had ich since (15 years!). Good luck and I hope yours pull through!

I agree with the above.

As for being 'concerned' or 'afraid' about stressing the fish- I was more worried about that when they were completely covered in ich and IMO close to death as it was. I have no problems or qualms about catching them now.

Also, although I feel the fish do still have ich, I don't feel you can ever completely get rid of it. Ich doesn't just randomly show up because your fish are stressed. It has to come from somewhere in your system.

If you follow proper QT for everything wet that enters your tank why cant you keep ich out?
