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.

Aquarium flow water pumps, sometimes referred to as power heads, are designed for maximum aquarium water movement and can be used with both saltwater and freshwater aquariums. These fish tank pumps do not have inlets or outlets for connecting to plumbing or other equipment. Many of these pumps, such as the 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 submersible aquarium water pumps in this category are often referred to as power heads and can be used with both saltwater and freshwater aquariums. These water pumps can be submerged in water and they can also be connected to plumbing. These water pumps have a wide variety of uses. For example, 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.

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, OASE, Lifegard Aquatics, IceCap, Reef Octopus, Reeflo, Penguin, Maxspect, Iwaki, AquaClear, Little Giant, and many more pump manufacturers.

Many aquariums, such as the Coralife BioCubes and Red Sea Aquariums, have a fish tank 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.

We're mostly an aquarium products company, but we also have a few pond pumps. Pond pumps often have a unique front cover for larger debris, and they are often not meant for use with salt water.

We carry a variety of air pumps from Coralife (Luft), JBJ (Maxum), Penn-Plax (Silent Air), OASE (OxyMax), and Tetra, as well as various air pump replacement parts and accessories (tubing, airstones, etc.).

We have a couple pump accessories that we highly recommend. Battery backups are a must for keeping your aquarium running during a power outage. Citric Acid will keep you pumps running for longer.
