The Aquatic Life Flow Swing Wavemaker silently and automatically produces natural-like waves which stimulates growth and transmits nutrients to corals and plants, while preventing "dead spots". The maintenance-free motor is perfectly sealed for submersing underwater and steadily moves the diffuser left to right and right to left, in two different speeds to imitate different wave-type currents. When the diffuser moves left to right, it takes approximately 5 seconds and when the diffuser moves right to left it takes about 10 seconds. This adjustment helps to sweep away excess debris. This wave maker can mount anywhere from a flat surface to a 90 degree angle with featured hinged suction cups, or it can be hung in the aquarium. Connection is easy with the choice of using the black PVC fitting which threads into the diffuser, or with the choice of using the barb fitting. Bring life-like currents into your aquarium to mimic nature's intensions and watch your aquarium come to life!
