The Rossmont Mover Water Circulation Pump product line are high performance pumps with compact dimensions. They're the smallest orientable aquarium circulation pumps (compared to other pumps of similar output) in the world. The wide and turbulent flow can be set to 120 degrees or concentrated to 60 degrees with the included concentrator nozzle. The Mover was developed to recreate the effect of the natural marine currents on barrier reefs. The Rossmont Mover pumps were designed and manufactured in Italy by the top engineers from Hydor and Sicce. Building on their successful pump designs for those other companies, the engineers at Rossmont have come up with the most state of the art water circulation pumps commercially available today!
