IMO:
From what I've seen the nmost successful sub-systems use mirical mud, live sand, some live rock, mangrove and caulerpa seeweed with some snails and limited but reversed lighting on the sub-system.
This is not the same as a Sump system, you rall want to wall off the environment in the primary chamber (remove the biomedia and replace with above. and the return area is where your pump, swkimmer and chemical media (charcoal) should be.
