Wake and I have the same idea for a Q tank. The only thing I generally do differently at all is to use a sponge filter with an air pump. The sponge can be placed inside your display for a week or so to help it colonize with bacteria. The water is not what cycles. Cycling refers to the process of beneficial bacteria colonizing your live rock and sand, enabling fish waste to be processed. The sponge filter will accomplish the same thing on a SHORT TERM basis. Sponge filters have the negative aspect of Nitrate production, but this is not relevant in Q because you will do a very large water change after each fish is finished in Q.

You attach the sponge filter to a power head. The Maxi Jet should work fine.

Another alternative is to use an air drive sponge filter. If you already have an air pump, this would be the less expensive option:

A hang on filter for water movement and carbon filtration would also be a nice addition. For that matter, you can attach the sponge to the intake of the hang on. Almost any idea works. You just need a place for water to flow across any material that allows bacteria to attach.
Don't waste a lot of money on this Brad. I probably have a tote full of this type of equipment in my garage that you are welcome to invade.
