Hypo QT help...

Well it has been a month and everything was going smoothly until the last couple days. Yesterday I lost a Lubbocks wrasse and today an lyretail anthias. They both look like their fins had disintegrated over night. Today I noticed a few other fish with their scales not looking the greatest. Any ideas on what might be causing this. The salinity is 1.008 - 1.009, pH has been between 7.7 and 8.0, and ammonia has been kept in check with Prime (wondering if the prime might be the culprit, or the fact that the QT wasn't cycled). The fish have not shown any signs of ammonia poisoning, breathing is normal. I have been doing 45% WC weekly or biweekly. This whole ordeal can't be over with quick enough. Thanks for any help you all might have.
 
You can try Melafix. You could be having some kind of bacterial infection causing fin rot. That can happen with hypo. Its easier for bacterial infection to take over in low salinity.
 
First, it's probably not bacteria, although you can certainly treat for it. My guess would be that it's a chemical burn that has killed your fish. Prime is certainly safe, but if used constantly on high volumes of ammonia (likely since you had an uncycled tank), it can and will cause burns to your fish. Prime doesn't magically remove ammonia, it just changes it to a far less toxic form - there is still some toxicity though. In smaller amounts, or over a short time, with plenty of water changes, then it is no issue. If used consistently, this less toxic form can still hurt your fish, and I have also read that prime itself if used a lot can do so, but I am not sure on that one. If I recall, hypo also makes ammonia and related chemicals more toxic? I'm not really sure on that one, I'd have to look it up, but regardless hypo is a relatively stressful situation for your fish to begin with.

If you still have fish in there, do a large water change, and buy some Tim's today, and dump the whole bottle in. Maybe even get a decent sized live rock or other live filtration and drop that in the tank too. Put more Tim's in tomorrow even... Good luck, I hope your remaining fish make it.
 
Thanks for the help. I might try a 100% WC tomorrow to restart any build up there probably is. My tangs look great (in fact never better), along with my flame wrasses, and most of the others, but the anthias, chalk basslet, and a couple others aren't looking the greatest. I will try and pick up a bottle of Tim's today and see if that doesn't help as well.

I was wondering if aggression could be the cause, but I was surprised to see their fins deteriorate over night. It all happened so suddenly that is why I am so confused.
