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 as it is designed to be connected directly to a 1" rigid PVC pipe. Bring life-like currents into your aquarium to mimic nature's intensions and watch your aquarium come to life!
