Fins Reef has a really unique product on their hands with the Xaqua X-Inout. It is a wavemaking system that is built right into the overflow box and return line. This interesting device requires zero electrical input. It works off of the existing water flow and pressure created by your return pump. The Xaqua X-Inout will require two holes drilled into the back of your aquarium to operate. So it might be difficult to incorporate it into an existing glass aquarium. Obviously acrylic tanks would be much easier to add this device to. Regardless of the aquarium, the Xaqua X-Inout creates some serious waves. I will admit I had my doubts, but these were quickly washed away when I saw the various videos of these things in action.

These wavemaking return systems will set you back approximately $180. But given the fact that it requires zero energy and therefore adds nothing to your operating expenses, it will very quickly pay for itself. See below for the Xaqua X-Inout’s features and additional information from Fins Reef. Stay tuned for a video of this neat little wavemaking device.
