Hi, Cah925
I, for one, would advise against the use of that type of fogger. They're rather prone to heating up the water, and have a nasty tendency to fry the diaphragm motor after a while. Personally, I've had much success with the cheap personal humidifiers that you can purchase at nearly any local general store. I think I came upon mine at Wal-Mart

You should be able to find some step-by-step guides on the web.
In brief, it costs less, keeps equipment out of the aquarium, and works much more reliably.
Good luck,
BP
