I lost a fish to ich last week and now I'm trying to pick up the pieces and start over. I've been advised to leave the main tank fallow for 4 -6 weeks for the ich to die off. In the meantime I want to get my QT ready for a new fish, but I dont know how to go about bio-filtration for the QT. I'm sure I cant use any sponge filter from the main tank at this time since it would be contaminated with ich. It looks like I cannot get my QT up and running until at least 4 - 6 weeks. Any suggestions? Thanks.
