Next question would be what kind of canister, it has to be able to close tight enough so that the pressure cause leaking. I was looking at things like this:
Plastic Pails And Lids
But I'm just not sure. The tank sits on a small TV stand which is about 2 feet off the ground and has a small area inside where I could store a tank if it were say a rectangular box.
I had thought about doing a sump but just don't see how I could easily drain the water from an established tank without drilling and such.
Also I am thinking I could build something like this for cheap, easily lass than $100.
