I remember seeing a thread not too long ago in which Dutchy mentioned shortening an intake tube to bring it just below the surface of the water. I'm currently using two canisters with sponges attached to the intakes to keep debris inside the filters to a minimum. They are a pain to clean however due to being down near the base of the plants in the corners. If I hacksaw these down to sit say 3 to 4 inches below the surface, is there any downside to doing this? Seems it would make the sponges much easier to clean and with two koralias and two outtake tubes all aimed at the front glass, my flow seems fairly consistent to push the debris off the bottom. Suggestions? advice?
