If you are wanting a DSB, then you are shooting for atleast 4" but 6" would be better. It would be good too if you get any fish that like to borrow. I have 100 pounds in my 65 gallon, so I would guess around 50 pounds, maybe a little more.
Wouldn't the tank cleaners take care of the stuff that gets trapped in the cc. Ie. shrimp, cucumber etc.
Maybe on the very top layer, but they will not be able to get down into the CC very deep because it is large and often sharp pieces which could actually injure bottom dwelling animals. Using sand prevents the debris from even getting down into the substrate, and what little does make it down will be taken care of by bacteria.
