Figured it out. Not the prettiest solution, but it works. The whole room is going to be gutted in the summer and everything is getting moved anyhow, so I'll live with it for now.

Chopped a hole in the shelving to attach the hoses. Fortunately, this is all below knee height.
This is how the tank looks for now. No more UGF and risers. Spray bar for the Fluval 305 up top. The Aquaclear is only there on the right until the Fluval is seeded well, I'm going to say three or four weeks.
That blasted Java moss is taking over! There's also a few Java Fern plantlets growing in there. Tangling them in the moss is the only way to keep them from sucking up into the filter until they grow out big enough to send to MudHog.
Tomorrow I'm going to mess around with the lunar light setup I got off of eBay. 6 wide angle lenses, taping the to the back of my PC light looked very promising, but I want a tidy set-up when done.
