It looked quite realistic and had none of the problems that comes with DSB. It is like having a BB tank but looks like it has a DSB. He just blows the detritus up into the water column. I'm seriusly considering this when I set up my 225 FOWLR.
I have coarse sand and crushed coral in my 90 gal reef; about 2-3 inches deep. There are things I like and don't like about it. It's easier to keep in place than the finer sand, but IMO doesn't look as good as the fine stuff. The 90 is 9 months old so I haven't really had any issues yet. I give it a bit of a stir from time to time and that's about it.

If I recall, the fake sandbed looked good for a few weeks and then got covered by more and more blotches of coralline. Seemed to be a lot of work for something that would only look neat and tidy for a short period of time.
