Water Circulation Ideas for a 240g Peninsula

[eho72]

I am in the planning stage of setting up a 240g (96x24x24) peninsula tank that will serve as a divider between the kitchen and family room. I like to have a clean look to the tank with no wires hanging out from the 3 sides that are viewable. The overflow will be against the wall and I plan on moving my 2 vortech mp40w there. Since this is such a long tank, what choice do I have to get water circulation all the way to the other end of the tank. Also what is a good recommendation for an external return pump. My current tank is a 120g so anything this big is unfamiliar territory for me.
