I think yu did a great job explaining the QT, but I have a question. They tell me I can use a sponge filter in my QT is this true? I am talking about a ten gal tank. I am sorry one more thaught. If I use a sponge "NEW" filter do I have to wait for the tank to cycle? I think I hado a form of ich and I have live rock and inverts in my 12 gal main. Would like to treat the main with hypo. if I can. How long will it take to clear the Tank out of these nasty parasite? .... sorry three questions
