I have had my tank running for about four months now with a DSB. It works for me so far. I have a lot of things that stir up the sand Dragon Goby, snails, crabs, and starfish. I suggest if you do go DSB, you might want to consider a Dragon Goby. The only drawback is the sand that ends up on the coral, can be taken care of with a turkey baster.
