Hey kevin, glad to have another salty dog in here. We need more people to be frequenters.
I dont think you will ever keep your sand bed from going anoxic no matter how many critters you put in it.
I aggree that I wouldnt do the bare bottom because I try to replicated nature as closely as possible.
A remote DSB is the only one that I would ever advocate. So many things can go wrong with an in tank one, and facts are facts, the ammount of food INTO the tank, will equal the ammount of waste OUT of the tank. Unless you dont disturb your sand bed. In which case it goes down into your 8" of sand and stays there rotting and making toxic gasses.
