Pumps & Powerheads

Shop Reliable Aquarium Pumps and Powerheads

Aquarium pumps and powerheads are pretty essential when it comes to keeping your tank water in good shape. Whether you’re working with freshwater or saltwater, these devices help keep things moving: they circulate the water, boost oxygen levels, and make sure waste gets carried off to the filter where it belongs. That constant movement is what helps your fish stay healthy and your water stay clean.

They’re used in different ways too, from helping with internal water flow to powering sump returns or external filters. You’ll find them in all sorts of forms. Submersible options like the AquaEL Circulator, Juwel ECCOFLOW, and OASE StreamMax Classic are popular for a reason. They run quietly, don’t take up much space, and do a solid job across a wide range of tank sizes. You can tweak the flow on many of them, which makes it easy to create natural water currents or run your filtration setup without disturbing your aquascape.

When you’re shopping for an aquarium pump or powerhead, think about your tank size, layout, and what kind of fish or plants you’re keeping. A planted tank usually does fine with moderate flow. For reef tanks, you’ll want something stronger and more directional. Features like magnetic mounts, quiet motors, energy efficiency, and adjustable flow settings are all worth paying attention to. If you’ve got a more complex setup, like canister filters or sump returns, pumps like the OASE OptiMax are built to provide steady, long-term output.

Maintenance is key if you want your equipment to last. Clean the impeller regularly and check that nothing’s clogging the intake. Saltwater setups might need a bit more attention, since mineral buildup can affect water flow. Also, place your powerhead thoughtfully. You want good circulation without creating currents that are too strong, especially in tanks with light substrate or delicate fish.

So whether you’re setting up a new reef tank or just need a better filter system, a reliable aquarium pump and powerhead can make all the difference. Check out our selection and find the one that suits your tank best.

FAQs About Aquarium Pumps

1. What does a powerhead do in an aquarium?
   It helps move the water around. That prevents dead spots, spreads nutrients and heat, and keeps filtration and oxygen exchange working properly.
2. How big of a pump do I need for my aquarium?
   A good rule is to go for something that turns over your tank’s water about 4 to 10 times per hour. For a 100L tank, that means a pump that delivers around 400 to 1000 L/h, depending on your specific setup.
3. Do fish tank pumps need to run continuously?
   Yes, they should. Turning them off for long periods can hurt your water quality and stress your fish, as well as affect the beneficial bacteria your tank depends on.
4. Where should I put my powerhead in my aquarium?
   Generally, somewhere in the middle or upper part of the tank works best. Angle it to encourage circular water movement, but avoid aiming it directly at delicate plants or slow-swimming fish.
5. Do powerheads oxygenate water?
   They do, indirectly. By increasing surface movement, they help oxygen enter the water while letting carbon dioxide escape.
6. What is the difference between a wavemaker and a powerhead?
   Powerheads provide a constant, directional flow of water. Wavemakers create pulsing or wave-like movements to mimic natural ocean currents. Some modern powerheads come with wavemaker features too.
7. How do I know if my fish pump is working properly?
   If water is flowing steadily and the pump runs quietly, you’re in good shape. But if the flow weakens or the pump starts making strange noises, it probably needs cleaning or replacement.
