Hey Jude (hehehe),
Actually I have pre planned for multiple tanks and have a 3.6 X 2.4m concrete block walled room downstairs set aside. I'm including a floor drain in the slab and as well a seperate power circut for the room (Will also have the hall light on this circut to warn me if it blows a fuse).
Matt, Cheers for the info. Sounds pretty much like what I should use.
