Ich QT Question

I currently have 4 fish in one large QT system. Yellow tang,blue tang, sailfin tang and a long nose hawkfish. All have been in Qt for 6 weeks today. The first week was just observation and the second week was just parzi. I started copper at .5 strength on 3 week and it has remained there for the last three weeks; I also did another round of parzi the week. Shortly after starting the copper treatment, the blue tang showed signs of ich (whites spots all over); none of the other fish exhibited signs of ich. The spots went away in about four days or so.

Can I be confident that the ich is gone? I need to remove the copper today as my understanding is that 4 weeks at .5 is the maximum exposure time. I can remove the copper and observe in QT for another week or so to be safe. Would i need to keep all the fish in QT for observation or just the blue since it is only one that exhibited any signs of icy--based on my reading cooper attacks ich in the swinging stage so i'm not sure how the parasite could have made it to the other fish. Thanks.
 
Personally, I would observe all the fish for one full month. It sounds like you've got it knocked out... but better safe than sorry.
 
ok tomorrow is two weeks without copper. No signs of ich and everyone is healthy and looking great. What is the consensus? Is it safe to add to the DT or should I keep them in QT longer?

I would give it one week longer time. In theory you would have exceeded a CI life cycle with no symptoms then.
 
Well, this should be a cautionary tale for all. I removed the first fish from QT today (the sailfin) and put him a speculum container to inspect before placing in the DT. He had ich. I have not idea how it could have survived the 28 day copper treatment, but it did. looks like I will have to run another round of cooper.
 
AGREED!! Everything is all good IF no spots have appeared in the last few weeks as you have said. Congrats and good luck!

Bummer. Are you certain you kept copper at therapeutic levels the entire period? Which copper treatment did you use and how often did you test?

0.05 or 0.50? If the former, that's way too low. Cupramine needs to be at least 0.35mg/L to be effective.

Yes. Also, what brand of test kit did you use? Many don't work with Cupramine. If you did no WCs and Cu remained steady for the four weeks, something is wrong. Cu should dissipate (or whatever the more chemically inclined call it) over the treatment period.
 
With no water changes.. in a QT how did your ammonia do? I thought Cupramine compromised the bacterial function in the filter? How big was your QT?

I am studying copper.. b/c next time I am going to try Copper instead of TT.
