And trillions of gallons of water over it. In fact, when one looks at the entire ocean floor, the area covered by live sand beds is very miniscule indeed. The natural inefficiency is compensated for by sheer volume.
Most of the sea floor is hard packed by pressure and also too cold to be of much use, and when one considers the sea volume-to-livesandbed ratio, it's almost like what you would get by putting a very small refugium on the back of a very big tank. However, it's obviously enough, and that's good, because it lets our refugiums work just fine.

Deep sand beds do work well enough for most applications, and I'm not saying they don't. I'm just saying that they don't work as well as the alternatives of plenums and ecosystem filters.

Getting back on subject...
In head-to-head comparisons, the ecosystem method outperforms all other methods by a very impressive margin. If the guy who started this thread is really serious about making his reef a success, he should really look into this method and do things right the first time.
