Marine Velvet

[RFD4]

I identified that my fish had Marine Velvet unfortunately to late for several of them. I now have them in QT - my tank is empty accept for some Inverts. Can anyone suggest the proper length of time to keep the tank dormant until I can introduce my fish back to the tank or any other suggestions to help my tank get back to normal.

I would leave your main tank fallow for at least 12 weeks. What are you treating the fish with?
