I am using the small section for a fudge I dont put sand in my sump it just catches all the junk and builds up nitrates after time, just live rock and macro. I think that water that flows thru the fudge needs to be reduced or there is little or no contact, I split off that section so I can have a reduced amout of flow. Works well so far.
