Kenis Wave Deflector is a rotating deflector that turns your exisiting power head into a wave maker. This device is design to fit most of the power heads, water pumps and even output of the canister filters. With its unique 360° rotating feature, the deflector is made with gears and roto fans around the units internally, so that water will flow through it causing a circular movement without added energy cost. In this way, the Wave Deflector help to improve water circulation, air exchange and most of all to simulate natural ocean conditions in your own reef aquarium with coral and inverterbrates.
