The new Reef Octopus OCTO Pulse 2-PM Flow Pump moves up to 1,600 gph and consumes no more than 10 watts of power in the process. The broad flow water movement will encourage coral growth instead of blasting it away with harmful "hot spots" associated with other wave pumps. It can be controlled by the WaveEngine LE Controller (not included). The WaveEngine LE can control two pumps. You will need an adapter to connect the pump to the WaveEngine. With its 360° magnetic mount, the OCTO Pulse can easily get the flow precisely where you need it. The rear of the OCTO Pulse has a convex rounded shape that fits neatly into a concave mounting magnet allowing the pump assembly to gyrate in any direction. The OCTO Pulse's low-profile magnetic mount offers a 25-degree range of motion and the entire pump is capable of rotating 360 degrees! Rating: Aquariums 20-80-+ Gallons. Maximum Flow: 1,600 Gallons Per Hour. Power Consumption: 5-10 Watts. Size (in): 2.83W x 2.48H. Tank Thickness: Up to 1/2" thick. Glass or Acrylic: Safe for Both.
