Whether you're building a backyard pond, installing a waterfall, or maintaining a koi pond, choosing the right pond pump starts with matching the pump to your water feature. This collection includes pond pumps from trusted brands like Little Giant and Atlantic Oase, with options ranging from compact magnetic-drive models for fountains to high-capacity external pumps that move up to 5,500 GPH for larger systems.
You can find the right water feature pump for fountains, waterfalls, filtration systems, and aeration. If you're unsure which model fits your pond, you can get help selecting the proper flow rate and pump style for your project,you'll also find everything you need in our pond supplies collection. Orders are available for pickup in Glenwood Springs or delivery across the Western Slope.
How to Choose the Right Pond Pump
The best pond pump depends on three factors: your pond size, the amount of water you need to move, and how you'll use it. A decorative fountain typically needs a different pump than a large waterfall or stocked koi pond.
You'll also want to decide between a submersible pond pump that sits underwater or an external model installed outside the pond. Once you've narrowed down the type, matching the gallons per hour (GPH) to your pond's volume helps keep water circulating properly.

Submersible Pumps vs. External (Out-of-Pond) Pumps
A submersible pond pump is installed directly in the pond, making it a popular choice for small and medium ponds, fountains, and decorative water features. Models like the Little Giant Submersible Direct Drive and magnetic-drive pumps offer simple installation and quiet operation.
An external pond pump sits outside the pond and is better suited for continuous operation and higher flow rates. These pumps work well for larger ponds, waterfalls, and long plumbing runs. If you're moving large volumes of water, the Out-of-Pond 2500 and 5500 GPH models provide the performance needed for a large pond pump application.
Matching Pump Flow to Pond Size
As a general guideline, your pond pump should circulate the entire pond about once every hour. For example, a 2,000-gallon pond typically benefits from a pump capable of moving around 2,000 GPH before accounting for elevation.
If your system includes a waterfall, stream, or long plumbing run, you'll need additional capacity to compensate for head height and friction loss. Choosing the correct waterfall pump helps maintain steady water movement while supporting healthy circulation throughout the pond.
Pumps for Fountains, Waterfalls, and Koi Ponds
Different water features place different demands on a pump. A fountain pump is designed for decorative displays and continuous water movement in smaller features. Magnetic-drive and Flex Pump models are excellent choices for these applications.
Waterfalls generally require higher flow rates, making dual-discharge or out-of-pond pumps a better fit. If you maintain a koi pond pump system, look for pumps that deliver strong circulation while pairing well with a filtration system to support water quality.
Pond Filtration and Aeration
A pond pump is the heart of the pond, keeping water moving; inside, an impeller acts like a fan blade to push water. Healthy ponds often benefit from both filtration and aeration, and fish ponds especially produce organic waste that can cloud the water if debris is not removed effectively.
Adding filtration and oxygen circulation creates a healthier environment for aquatic life while helping keep water cleaner throughout the season. You can also improve overall water quality with pond water treatments when needed.
When to Add a Filter
If your pond contains fish or receives significant debris from surrounding trees, pairing a pond pump and filter is recommended. The pump circulates water while the filter removes suspended particles and biological waste.
The Pressurized Filter with Backwash makes routine maintenance easier and helps maintain clearer water. You can also pair it with Matala pond filter products to support biological filtration.
Aeration for Healthy Water
A pond aerator increases oxygen levels and improves circulation, especially during warmer months when dissolved oxygen naturally drops. Better oxygen supports fish health and beneficial bacteria that help break down waste.
Aeration can also help maintain an opening in the ice during Colorado winters. The Shallow Water Aeration System provides an effective solution for ponds that benefit from year-round circulation.
