External Aquarium Water Pumps, Main System

External saltwater and freshwater main water pumps for aquarium systems typically are often under the tank or next to the sump. The largest aquarium water pumps we carry (Iwaki, ReeFlo, Abyzz) fit into this category. Some of the aquarium pumps in this section, such as the Hydor SeltzD, and Reef Octopus, can either be used submersed or externally and can have plumbing connected to both the intake and return. Some of these smaller pumps can be controlled. If your external pump is in or next to the sump, or if there is a great deal of back pressure on the pump from a filter or a long vertical rise (e.g. pump in the basement), you will want to purchase a high head pressure rated pump.External Pumps By Size:External Water Pumps: Up to 1000 gphIExternal Water Pumps: 1000 to 2000 gphIExternal Water Pumps: Over 2000 gph.Related Products:Submersible Pumps for AquariumsFlow Pumps & Wavemakers for AquariumsIWater Pump Replacement Parts.
