Melev's usually pointed to for layout examples.

Me, just using a 75G for basically a 2 section sump (bubble tower/filter sock/skimmer section, 3 baffles, then the pump return section) with a separate 20g above for a fuge. Can't really see much reason to get fancier, other than I'm thinking about a egg-crate shelf in the pump return section for some frags.
