Ok, all inhale ever had is canister filters. My new tank has a sump underneath. What I have is water from tank comes down into on baffle and them runs into another spot and that area is bigger and has some live rock and also my Diablo skimmer in there, it then goes from there to another spot that my return pump is hooked to. Question is do I put any media in there anyweres beside live rock? There is a filter sponge between the spot were my skimmer is and the return.
