Sick Fish - Can't solve the problem

[Jaws]

So about a week ago my tank came down with velvet, or at least what looked like velvet. After I added about 30 pounds of live rock from another reefer's tank, all the fish started showing signs of blotchy skin, heavy breathing, and erratic behavior within about 24 hours. They definitely had some kind of parasite so I removed all the fish, placed them in quarantine and treated with chloroquine phosphate about a week and a half ago. They seemed to bounce back pretty quick over the next few days. All looked good and were eating well. Then about 3 days ago all the fish decided to go on a hunger strike. Now some of their fins are starting to deteriorate and they're showing signs of blotchy skin and swimming funny again. Temp is 78, pH is 8.1, NO3 is under 5, PO4 is 0.1 and Alk is 10. I've got power heads pointed up too so there's lots of surface agitation for added oxygen. Am I missing something? I can't stand sitting here and watching them get worse. If anyone has any other suggestions I'm all ears. Thanks.

I am no expert but my thoughts went to what your ammonia reading is at with that new rock?

[Jaws]

I didn't test ammonia but the rock was cycled for months before I added it. There was only about 30 pounds of rock in 700G of water volume too so it shouldn't be ammonia. I'll check though to be safe.

Sounds like ammonia poisoning

That's how it sounds to me too , maybe worth a check to be sure.

Adding some prime, amquel or other amonia binder would help if that's the case.

Ok so I added some prime first thing this morning. I'll do a water change tonight and turn on the carbon reactor too. My ammonia test kit seems to be missing so I'll have to pickup a new one today. Is this something the fish can recover from or is it bad news once they've been exposed?

yes they can if the damage isn't to bad

is it possible during the treatment process they were exposed to amonia?

[Jaws]

None that I can think of. Even if that rock was dead or dry, 30 pounds of dead or dry rock shouldn't effect 300G of cycled water should it?

30lbs shouldn't IMO but i guess it comes down to whats inside the rock

Are you just using 30 pounds to filter 300g of water?
