I have a ? about everyones fuge. Who does are doesn't have a sand bottom in their fuge. Why I ask is because I'm getting a lot of debris in my tank and doesn't matter if I turn the flow down or up. I 've heard of people just using a few pcs of LR and the rest Cheato. If so will that work without the sand bed. And also have filter sponge where ever I can put it between the baffles and use filter socks.
