Fish Tank Air and Water Pumps

Whether you have a small freshwater tank or a large marine aquarium, we make it easy to aerate the water with a variety of fish tank pumps, and provide your fish with a safe, healthy home. A water pump or powerhead is used to circulate the water, sometimes directly through a filter in the case of powerheads. On the other hand, aquarium air pumps can provide secondary circulation, power undergravel filtration or create beautiful bubble effects with air stones and bubble walls. Every tank is unique, so the size and capacity of a water pump will depend on the size of your aquarium as well as the type of filtration, fish, plants and invertebrates that live there. Saltwater fish tanks require a higher water flow rate than a planted freshwater aquarium, which can get by with small water pumps. Submersible water pumps are easy to install and relatively quiet because they run entirely underwater. However, they generate heat which transfers to the water and may require a chiller to offset higher temperatures. In-line water pumps generally move more water, but have specific configuration needs and require more maintenance. Some pumps can be used as either an in-line or a submersible pump. Aquarium bubblers attach to air pumps using airline tubing to create bubbles in a fish tank. You can keep it simple with a small air stone, or add sophistication to your aquarium with a beautiful bubble wall and LED light display. Many aquarium ornaments pair well with bubblers, creating live volcanos and adding motion to underwater ancient ruins and shipwrecks. With high-quality fish tank air and water pumps, including powerheads, submersible water pumps, air stones, airline tubing, bubblers, valves and suction cups, as well as pro-quality magnetic drive pumps, you can aerate their aquarium in the way that suits it best.
