help with quarentine tank?

[albionpo]

I'd like to be a little more prepared with my QT so that I can use it at a moments notice...I don't keep it up & running so...if I put the sponge filter from my little aquaclear filter ( that goes on the QT ) inside my Emperor 400 ( on my show tank ) would it build up the nitrifting bacteria in there? So I could then use 80% of my tank water , 20% new water & this sponge filter to set up a QT fairly quickly? Would this work?

Yes, that would be a quick way to start. I just have an old 40 with LR and my old lights, cirulation only as a QT.
