A wavemaker makes your tank look more realistic. It allows tall plants to move fluidly and helps fish to feel the water moving around them. It simulates the movement in the real habitat. Another benefit of having a wavemaker is that it promotes water circulation so that all parts of the aquarium have access to fresh oxygenated water, further improving the health of your fish. If you happen to keep coral and other living decor in the tank, then it is essential to have a wavemaker, as these creatures rely on the movement of the water to supply them with the necessary nutrients Specification:Voltage: 110-120V/ 60HzFrequency: 60HzPower: 8WOutput: 6000L/H (1585gph)Dimension: 7770126mm (32.755 inches)Package Content:1x Submersible Wave Maker 360 Degree Circulation For Aquarium Fish Tank -1600Gph
