Very cool! If you remember my results posted in the old thread ( I even made a little diagram/drawing) is is what I experienced when I moved my filter pipes to the front/back.
I didn't get the wave motion, but the direction of the water was the same. Due to the lily pipes shape it was swirling around in the motion you see above, but also pulling from the end of the tank opposite the outflow and dragging water to the inflow.
One day, I would love to get that pump system when I get a bigger tank.
