Aquarium Pumps Useful Articles: Aquarium Pump Overview Why Use A DC Aquarium Pump? Why Should You Use A Wavemaker? We have over two hundred pumps for aquariums. These pumps range from 70 gph pumps to 6000 gph pumps. We have pumps you can control with a smart phone and pumps that can re-create the wave action of the ocean. We have pumps that run outside water, pumps that run inside water and pumps that will run either way. We have pumps with 90 day warranties and pumps with 5 year warranties. We have pumps that cost less than a pack of cigarettes and pumps that cost nearly $500. If you have an aquarium, we have a pump for you. External Main System Pumps for Aquariums External main system pumps typically are under the tank or next to the sump. The largest pumps we carry (Iwaki, Little Giant & ReeFlo) fit into this category. Some of the pumps in this section, such as the Rossmont Riser and Hydor SeltzD & Reef Octopus, can either be used submersed or externally. Some of these smaller pumps can be controlled. The pumps in this section can have plumbing connected to both the intake and return. 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. Flow Pumps & Wavemakers for Aquariums Flow pumps, sometimes referred to as power heads, are designed for maximum water movement. These pumps do not have inlets or outlets for connecting to plumbing or other equipment. Many of these pumps, such as the Rossmont Mover and Hydor Koralia, have a very large round outlet. In recent years we have seen the emergence of gyre-style flow pumps, such as the Maxspect Gyre and IceCap Gyre.  The more sophisticated flow pumps either have a controller or can be connected to a controller to create wave flow. Submersible Pumps for Aquariums The pumps in this category are often referred to as power heads. These pumps, such as the Lifegard Quiet One Pro and Supreme Magnetic Drive, can be submersed in water and they can also be connected to plumbing. These pumps have a wide variety of uses. They might be used as a main system pump submersed in the sump or aquarium. They might also have a filter, uv, chiller or in-line heater between the pump and the return to the tank. Or, they may be used to power a specific piece of equipment, such as a media reactor, UV sterilizer, chiller or protein skimmer. Aquarium Pump Replacement Parts Along with the usual breakable/wearable parts—impellers and impeller shafts—we carry volutes, covers, o-rings, pre-filters and more for the various pumps we sell. This includes pumps from Hydor, Lifegard Aquatics, IceCap, Maxspect, Iwaki, Little Giant and many more pump manufacturers. Aquarium Pump Replacements for Aquariums Many aquariums, such as the Coralife BioCubes and Red Sea Aquariums, have a pump specifically made for that aquarium. Although other pumps may be adequate replacements for the stock pump, when it comes time to replace a BioCube Pump or Red Sea Max Pump, the stock pump is usually the best and easiest choice. Pond Pumps We're mostly an aquarium products company, but we also have a good selection of pond pumps. Pond pumps often have a unique front cover for larger debris, and they are often not meant for use with salt water. Pump Accessories
