As Marc said, it all depends on your design and what you plan on keeping. Bare bottom tanks are very successful, and used primarily on SPS
tanks w/ high end skimmers and very high water flow. That prevents detritus from building up and reeking havoc. I think DSB
's (4"+) are a dying thing due too nutrient issues, etc over time, as mentioned. A shallow sand bed- ~2-3"- looks good and functions well for mixed reefs IMO
