Welcome to another episode of BRStv Flow Dynamics, where each week we dig into various pumps to show you a visual representation of their flow pattern to help you make a more informed decision on what will work for your tank. The Sicce Voyager HP pumps are high quality, reliable, and European built. These are one of the few true AC powerheads that can be run on a wavemaker function with virtually no clicking noise. Features: Power Usage - 38.9 W Dimensions - 6.81" x 3.6" x 3.67" Maximum Flow - 4000GPH
