What should I do?

Imo the proper thing to do is put fish in display tank. If a qt tank is wanted, then set it up properly prior to puutting fish in.

 

if you keep the ammonia levels at .25 or below. it is probably fine for the fish.
howsboutafiver the reason people qt fish is to prevent deseases like marine velvet from getting into the display tank. Have you ever lost your entire live stock in a 200g system to adding a non qt fish?

 

Ammonia test kits can not distinguish ammonia from the amine based complex present in Cupramine and will therefore give a false high reading for ammonia while using Cupramine. Our Ammonia Alert and MultiTest: Free & Total Ammonia test kit do not suffer from this problem as they utilize a gas exchange technology that can distinguish ammonia from amines.

From seachems website, if you even are using cupramine, I can't remember

 

No meds just prime.

 

Ah, well worth a shot.

 

Good information to know though.

 

I read many threads on the setup of QT's and followed those directions. A vast majority of the recommendations was a non-cycled tank using water from your DT and a seeded sponge from the DT as well. That is what I did. I had a sponge in the return section of my sump from the day I started the tank. When I was ready to get a fish, I called the lfs to find out what their salinity is and set my QT to that. Once that was established, I brought home the fish, floated the bag, double checked the salinity in the bag, and then added just the fish to the tank. I then slowly raised the salinity to match my DT level. The first few days my readings were zero, then they climbed to where they are now, around .25 for ammonia and nitrite. I have been able to keep them in check with daily water changes and prime.

 

If your levels continue to climb I would maybe add some more LR from your DT if for nothing else to keep you from having to do so many WC's. Good luck.

 

Well after fighting the ammonia/nitrite problem in my QT, I bit the bullet and transferred my fish to my DT. I was doing daily water changes and using prime in my qt but the levels would not stay down. I suspect that the bio-wheel in my hob is causing a cycle. I came home from work yesterday and noticed that the ammonia alert badge had changed color to alert. Did a 25% water change with prime and an hour later the color had not changed. I did not want my fish to have to suffer any longer in this tank while it is going through its cycle. Luckily it is the only fish in my DT and I will continue to monitor it closely for the next week and a half, as this is all it had left in the QT anyway. I am going to let the QT finish its cycle before I add another. So far the fish is doing great in the DT.
