Nah I'm not going to jump over anyone. I mean I still think the issue with DSB is not a dirty problem so much as it is a newbie problem, since most start out in this direction, and you make mistakes with overfeeding it really sticks with you a long time.
Anyways, yeah, why the need for nitrate control in a barebottom, I thought nitrates weren't an issue since you could keep everything suspended and removed?? (ok sorry had to get that one in

)
I can't comment on any experience, since I have sand in all my tanks, when I move them I might stick with a DSB in a refugium (I'm also considering a surge through the refugium so I get some "tidal" action, but don't know how that'll work for the whole "refuge" aspect of things), and then a SSB with the tanks or try to grow something along the bottoms to cover up the acrylic (something other than coraline). But I really don't know, its something I still am pondering over.
One thing I always throught of doing was siphoning out my existing sand, cleaning it out, and then slowly reintroducing it back into the tank. Sure any critters are gone, sure bacterial populations are reduced but you wouldn't siphon out THAT much of the sand at once, but you get the best of both worlds in that get that patch of sand free of detritius. Eitherway I'm staying away from the "experts" opinions, since seems none of them can make up their mind one way or another as to a consensus.
