I am in the final stages of curing my BC29 of ICH. The tank has been fallow for nine weeks, my 6 line Wrasse has been in the OT tank undergoing a hyposalinty treatment. My question is, when I move the Wrasse back to the cube what do I need to do to my QT tank as far as sterilizing it & making it a QT tank for new fish again? Will a vinegar solution soak & wash be good enough? Also I was using a HOB filter (with a sponge) can I reuse it after proper cleaning & toss it back in my sump?
