3' deep substrate is the rule of thumb

It�s recommended to have a 2" or 3" deep susbtrate, because if it is too
deep, dead spaces will form causing lots of hydrogen sulfide.
I have a 2" sand substrate and it works great because when i move it, lots
of nitrogen bubbles go up to the surface, which proves that anaerobic
bacteria are doing their job.
Also a fine sand substrate will not clogg by detritus, because the sand is
so fine that it can�t penetrate into it, it will just stay over the sand
until it desintegrates and the filter and skimmer takes care of it.

I have also heard about the dangers of making the sand bed too deep which
can lead to "dead" spots. These can release sulfur dioxide into the water
killing most of the tank. It's very important to have lots of sand stirring
organisms to keep the bed well mixed. FWIW
