Hi Guys,\r\n\r\nThe JBJ 28 gallon nano comes with a filter basket that slides into the sump behind the main tank. The far left and right compartments house the power heads, and immediately adjacent, left and right is a compartment of a heater and protein skimmer. I will have a heater and skimmer when the time comes. \r\n\r\nMy question is...If I am doing live sand/ live rock (30 lb/50lb, respectively), do I need to set up the little filter compartment (sponge, charcoal, ceramic tubes- like ditilini!) or is the live rock/sand enough? Better still, if I have live rock left over, small enough, should I put that in the sump area where the filter basket goes?\r\n\r\nThe set up is a ways away ($$$), but I'm getting excited!
