okay, I made a mistake by buying a six line wrasse and not qting it first. He is the first fish in my 45g. He has ich for 3 days now. I bought a 10g tank with the regular Aqua Clear filter, heater and some ich medication today. I've added the water from the main tank. What do I do now. I checked ph and nitrates both 0. I have a cannister filter and a Aqua Biofilter on the main tank. Do i take one of the filters out and put it into the QT filter? When do i add the wrasse to the QT and can i treat with the ich medication ICK GUARD.
