Man, everybody has different setups for what seems to be the same thing. I could do a tray of ceramic rings, which are probably what I called noodles, with a polishing pad on top, then a tray of carbon, and a tray of sponges. Sound good? What do I put the carbon into so it doesn't go everywhere? It just came in a box, which seems kind of stupid. Does it matter what order these go from top to bottom? I guess the filter works from the top down right?
