VUPPA-II is an improved and evolved version of the original VUPPA-I. The original VUPPA-I was a pioneering invention (by Aqua Design Amano) that helped solved the nuisance of surface film in aquariums. VUPPA-II adopts an internal floating switch that prevents cavitation caused by a water level change. The new rectangular shape resonates with the shape of Cube Garden Aquariums. The components have been reworked and simplified to facilitate maintenance. The body of the VUPPA-II is crafted completely of stainless steel for modern unobtrusive aesthetics and durability. *For fresh water only*Patented product*Voltage / AC100V- 240V 50/60Hz SPECIFICATION: Article Code Size (mm) - 105-803 W43×D43×H130 USB Power Adapter 5V/1A (Type A plug) is included -
