What works great for a waterfall/gravity is to take a socket that is just big enough to fit in the hole, but not so small that it falls though. Put a screen in it. (or one from a sink if you're that cheap) What i use is a bottle cap with a hole drilled though the center and a metal bowl form a pipe that screws into the bottle cap. Works like a charm.
