So 1 of my fish came down with ich, so I moved him to the QT tank. I am running an aquaclear 50 on the tank. I only kept the sponge in there. After medicating the tank, I noticed the water was crystal clear 4 hours later (it should have been blue.) The sponge in the filter removed all the meds. So I removed the sponge. Should anything be kept in the filter on the QT tank?
