Franklin went out and tested the power consumption of the resun pump on a Vertex 250 skimmer at Aquatic Addictions........ the pump says 145 watts but when he tested it with a watt meter....... it drew 67 watts. Franklin thinks it's because the 145 is drawing all water and the 67 is water and air mixture which requires less energy to pump.
