eFlux accessory wave pumps make it easy to add additional current or waves to any Orbit IC LED light or eFlux Wave Pump kit. With LOOP control, eFlux wave pumps are able to mimic ocean waves and surging currents in entirely new ways. This isn’t only cool for you, its vital for your corals and reef inhabitants.  They provide tank wide circulation, improving water quality and promoting strong coral growth and fish health. LOOP control allows you to adjust flow mode, velocity, sync pumps, even turn them off for feeding.
