I have avoided wading in on this one, but here goes. If you put all three pumps on one side and can find the right frequency for turning them on/off, you MIGHT get a wave. You will need an adjustable timer that can turn on/off every 1-20 seconds or so. You MIGHT be able to find the right pulse that will cause a wave to start and build. Unmodded MJs will work (don't know anythign about the AquaClears) as they aren't prop driven so the AC thing shouldn't work against you. You will shorten the life of your pumps doing this and it isn't guaranteed to work. Depends on how fast those pumps start and stop and how regularly they do so. It won't be as pronounced as a wavebox either.
