Bare Bottom Tanks

[Richer]

BB tanks are advantageous because you can put in a large amount of flow through your tank without kicking up a sandstorm. Having a large amount of flow allows you to keep detritus suspended in the water column for your filters to take out (ie. skimmers, sumps, foam, etc.). This in turn helps you keep your tank cleaner (assuming you have a good upkeep routine for your filtration devices). Some corals also like large amount of water movement (read as flow, not velocity).

I'm sure other people will probably chime in, but thats my general thought on BB systems. I run one, and I like it.
