For the record, what exactly happens in a dsb?
Exactly what role do critters play in this process?
What role do bacteria play in hypoxic environments?
What role do bacteria play in anaerobic environments?
What do these bacteria feed on?
What exactly happens to detritus (in a reef tank) that is not mechanically removed? (or eaten)
What is the advantage of a RDSB over a DSB?
I apologize for the rhetoric. It seems that I am unqualifed to comment.

Here is the first post of two thread that Anthony Calfo said:
it is a modest strategy and dependant on bioload of course. But so cheap to employ, and easy to remove if you don't like it.
My LFS finally tried this with a 55 gall tank full (nearly to the top) of sand with a good stream of water traversing the length of the tank. It was staggering how fast it reduced nitrates on a nearly 2K gallon system.
A 5 gallon bucket with a 60lb bag of sand filling it can do similar/remarkable work on say a 90-120 gallon tank. A larger plastic garbage can (kitchen size... 20 gall or so) with a couple hundred lbs of sand, etc.
The goal here is denitrification and buffering (if using aragonite).
There are not many other benefits... and not many risks either. Unlit and with a strong stream of water over it, its a fairly brainless application Cover it and keep it dark... there is little to maintenance to speak of for it. You can imagine that with the good water flow (key) or even mechanically prefiltered water... there is no way for this to practically become a nutrient sink, as the small fast volume of water cruising over it do not allow the settling/sinking of much solid matter over time.
You need to go back to the first last thread and you will see the same questions and answers for this RDSB.
