I was lucky enough to have found and bought an unusual shape tank earlier this year, from a well-known classified site. I've since moved house and am looking to set up this new tank in my bedroom (which is bad for feng shui, but there's nowhere else to put it).
The tank is literally two hexagonal-shaped tanks, each about a foot wide, and joined by two tunnels in the middle.
Unfortunately I don't have a photo to hand, but it looks something like this:

The tank has lids on both sides, and two light sockets, an air pump and a heater are connected to it somehow, so that they're all powered using one plug.
I've yet to decide how to set the tank up, but my concern right now is with filtering. I've removed the undergravel filtering that came with the tank, as it left the tank extremely dirty when it was first used.
Any recommendations for what can I use in its place? I've estimated that it's a ten gallon tank.

Internals are possibly the easiest option. An external with the intake in one side and the output in the other is also possible but you would need to ensure that you have sufficient flow to ensure good circulation in the tank, perhaps by using flow pumps or powerheads as well.
Whichever method you choose you are going to need a fair bit of regular tank maintenance to compensate for the shape and impracticalities of the tank.

I'm sure i've seen that tank somewhere? Looked good but i thought - how the heck do you filter that! lol.
I reckon you would need to filter both sides seperately no matter what method you choose. I don't think you'd get any flow or just very turbulent flow if you tried filtering both with one method.
An internal either side (like Matt said) is probably simplest. If you were to use Chris' method of an external with intake one side and out put the other you will definitely need some powerheads etc to move the water about - you would otherwise get a load of stagnant areas.
I reckon that the undergravel is probably the way to go (I'm assuming it had an UG plate in each section?). Probably just needs a really good clean out.

I was thinking of using the attached air pump to create bubbles under the gravel - I don't know if that would help (enough) with the flow of water or not.
Ideally I'd use an external filter, though for a tank of this size I'd imagine it would be excessive. Two internal filters sounds like the best plan. I'm not sure about using the underground filters again as I would want to have one or two plants in the tank.
The tank looks exactly like this (though it's empty and cleaned out, and has never looked this good).
