I recently had an outbreak of ick or velvet in my 240 gal reef display. Actually believe it was velvet but can't be sure. About a week ago I relocated the ~30 fish to a 72 and 46 gal QT and will go fallow for ~72 days. The fish include a cheveron, blond naso, black, yellow and purple tang. All fish are being treated with Cupramine at ~0.5mg/L for about the past week. The last couple of days my Black Tang has stopped eating. He was initially in the 72 with the other tangs. I've since moved him to the 46 where he was the only tang but still not eating (tried everying nori, garlic, ect). He still has good weight on him but it's been my experience once they stop eating in QT it is unlikely they will start. As a last resort I decrease the Cu to ~0.4mg/L to see if this doesn't help.
I still have one final idea on how to save him, it would be possible to move him to a 30 gal reef tank tied into my main display. My display is 240 gal, this tank sits below the main display and is tied into the same sump. I could put my 50W UV setup on the drain of the 30 gal. In theory this will kill the ick/velvet before it is cycled back into the main display. Flow through the UV would be very low, maybe only 50 gal/hour so the idea being everything would be killed before cycling back into the main display.
My reasoning here is first and foremost to save the Black Tang. I realize I'll then need to go fallow in the 30 gal tank for another 76 days but that isn't a big deal since it is typically fallow anyway. Once the other fish are ready to be put back into the display I would move the black back to QT and try treating him again, maybe this time try hypo. What are the chances ick/velvet will slip past the UV and make it into my display?Again, flow will be very low ~50 gal/hour, can even go lower if necessary.
Thought and input are welcome.
