Aquarium Pumps & Supplies

Aquarium pumps enhance the circulation of water through your fish tank. These pumps help replenish oxygen for marine animals and improve the functionality of decorative accents and certain water filters. The continuous movement also prevents contaminants from growing in stagnant water. By releasing harmful carbon dioxide, an aquarium pump helps the water maintain a stable pH.

How an aquarium air pump works

1. The pump pushes air through a hose located under the water.
2. The pump creates micro-bubbles that stir the water and enhances oxygen transfer.
3. At the surface, carbon dioxide is exchanged for oxygen (aeration).
4. The pump moves the oxygen lower into the tank.

Why you may need an aquarium pump

• • Some tank decorations require them. Airstones need them to lift bubbles, and features with wheels or valves need them to turn.
• • Some filters, like sponge or under-gravel, and protein skimmers require a pump to perform properly.
• • Larger aquariums need pumps to transport oxygen deeper.
• • Aquariums consisting of warm water need a pump since warmer temperatures retain less oxygen.

Types of Aquarium Pumps

Submersible Pump

Submersible pumps are submerged under water. They work best for taller, deeper aquariums, usually with a volume of 50 gallons or more.

External Pump

Centrifugal and peristaltic pumps are all placed outside the tank. Centrifugal pumps can transport large volumes of water, and peristaltic pumps are best for moving specified amounts.

Aquarium Supplies

An airstone, or a bubbler, increases aeration and creates bubbling effects in the tank. You should replace your airstone every 3-4 months, so bacteria and algae don’t clog the pores.

Filter bags cover your aquarium pump so sediment and other particles don’t get trapped inside.

A check valve prevents water from flowing back into your pump.
