Without trying to open up too much debate on this topic, I'm sort of torn, for my 280, I want the benefits of a clean BB tank, but I like the look of a sandbed (at least when it's nice and clean). But I have to admit that there's no way that over the typical lifespan of a reef tank that I'm going to keep up with weekly vacuuming and whatnot. But then again, I don't want the sand for filtration, I just want it to look like a sea floor and not an aquarium floor.

Get a strip of fiberglass sheeting...make the shapes you want..bumps, valleys etc..expoxy aragonite over it the thin fiberglass(like thick paper...)
