Any of the turbelle, stream, controllable tunze pumps... Should be possible to wire up other low voltage pumps in the right voltage range with the right plugs...doesn't work with the low end tunze pumps
I am still looking forward to seeing how the gyre on pulse will work with my wavebox (which I wouldn't go without). I have ancient tunze pumps that just keep on going and going as well as a newer 6095 wide flow that gives a less penetrating flow over a very wide area. I am a fan of their water movers and the choices of flow types.
