I need some advice here. How important is mechanical filtration? I have a sump with a skimmer and a filter pad on top running water from tank into the drip chamber. I also have a sponge in my over flow box. I would like to convert my drip chamber of my sump into a fuge, but I would lose that filter pad in the process, because I would think the filter holder would need to go in order to have a light on top. Or would a light to the side work, and leave the top alone and keep the pad in place? Any thoughts on this would be great!!
Thanks
Jim
