There are lots of materials that facilitate reef construction, everything from cable ties, heavy mono fishing line, stainless steel wire, eggcrate, fiberglass grating, plastic screws, marine epoxy, Z-Spar epoxy, cements, Cyanoacrylate, hotglue, and combinations of all of them. The only limit is your imagination.

Rock can be sliced and glued directly to the back glass with polyurethane foam.

Having your rock supported on an open frame work actually allows better water circulation. Mine is barebottom under the rock with a shallow sandbed in front. I have never had a problem with detrius build up at all.
It's a more open rock work and you use less rock.

Some people have tied in their closed loops to the rock frame work for even more circulation.

Backgrounds can make a big difference in the 3-d effect of your tank as well. Rear lit translucent backdrops or removable in-tank backdrops can give the illusion of depth as does hiding the line where the bottom meets the backdrop.
A lot of people let coraline cover the back wall but it can be spotty and messy looking. (see The Reef Aquarium Vol.3)


For inspiration look at pictures of real reefs, and make a sketch or a model of the footprint of your tank and play around with what you would like to do.
