Hey guys I’m here with some sort of somber news, I’d been treating my fish for velvet and they did sadly kick the bucket, there were in a qt bin that had a sponge filter some media to hold bacteria and a heater and finally pvc decorations, I was wondering as the bin of as used for treating velvet what should I do to clear it of velvet or any parasites since I want to put fish I plan to get in it to qt them whilst my actual reef tank is in the no fish phase
