Sick Fish - Can't solve the problem

[Myka]

Ok, so you had the 400 and the 300 plumbed together, added the rock to the 300, fish got sick, moved them from the 400 to the 300 and closed the tanks off from eachother. Then you removed the 30 lbs rock and added some seeded foam?

Ok...

Still, in treatment tanks, I don't like to rely on biological bacteria to take care of the ammonia. I have Ammonia Alert badges in every system. They've saved my hide more than once. FWIW, AmQuel is much more concentrated than Prime, doesn't stink, and is cheaper. Use the bottle to figure out a dose, but re-dose if the ammonia isn't gone. I know the bottle says something about not overdosing. If there is ammonia for it to "eat" then you are not overdosing. Overdosing is the addition of the detoxifier when there is no ammonia to "eat".

So how are things coming along?

Well I wish I had a definitive answer but unfortunately I don't. I brought some water into Safari before I hit the system with Prime and Japarto didn't get around to testing it until yesterday but all the parameters came back perfect so he doesn't know what's going on. I suppose the reason the first test came back positive with ammonia is because that water was from after I hit it with prime and Christina tested that the day of. After doing the water change, almost all the fish have bounced back. Everyone's showing promise with eating again except the powder blue and the purple tang. They just hide in a corner together which is never good. I'm going to do another water change tonight plus I've turned my skimmer and carbon reactor back online and added my filter socks again to help with bacteria so I'll just have to keep an eye on things, which isn't going to be easy with my wedding this weekend and a honeymoon next week So far most of the fish are doing better though. I did lose my sailfin tang though sadly.
