IMO, IME a BB tank or a tank with a shallow sand bed is just about the same thing (function wise). I don't like DSB's because IME it adds to increased phosphates.
No matter what method you choose the same principals apply. Keep you water clean by exporting the wastes. Skimming, water changes, media, natural filtration methods if you wish.
I like a very shallow sandbed because it is clean looking and provides a nice contrast for corals that you keep on the bottom.....and IMO increased surface area for bacteria to grow can't hurt.
