Pond Supplies & More

We have all the products to make your dream water feature a reality. Choose from a complete selection of pond liner, pumps, filters, aeration, treatments, fish food, lighting, and much more!


Aeration is an extremely important piece of a healthy ecosystem for your koi & goldfish. Oxygen levels can fluctuate drastically which can directly affect the health of your fish. With our complete selection of aerators and aeration systems it's hard not to find one to fit your application.

Algae Control

With fish waste, uneaten fish food, sunlight, and the right temperature, algae can quickly get out of control in your pond. Between pea soup green water to string algae in your waterfall, we have the treatments to get your pond back on track. The majority of these treatments will kill the algae for a quick fix, but they will not prevent regrowth. Once the algae is treated, use proactive products such as beneficial bacteria to reduce future growth.

Aquatic Plants

Plants help bring the finishing touches to your pond or water feature, while also helping create and maintain a healthy balanced ecosystem. Consider exotic lotus flowers accented with hardy and tropical lilies. Landscape the edges and accent waterfalls with shallow water marginal plants. Floating plants such as hyacinths and lettuce will help shade the pond and reduce algae. Try to mix textures, leaf sizes and foliage tones and shapes for a variety of aesthetics, while making sure to include the all-important oxygenators.

Decorative Water Features

Add a unique touch to your outdoor living space with these decorative features. Choose from container water gardens, stand-alone fountains, bubbling stone and decorative spitters. Most can easily be installed in an existing system.


To support aquatic life, every pond will require some level of filtration. There are mainly two types- mechanical and biological. Through both forms, the pond will process a variety of nutrients in the pond, including fish waste, uneaten fish food and accumulated debris. Whether choosing from an external or submersible, pressurized or gravity fed system- selecting the right filter for your pond should not be underestimated.

Filter Pads & Media

Nothing lasts forever. Filter pads and media will eventually need to be replaced, so they can continue to filter debris and muck out of your pond. You'll find everything you need here for both mechanical and biological filtration.

Fish Food

Fish, like all animals, need food to survive. Our premium selection of fish food for koi and goldfish covers all major brands including Microbe-Lift, Hikari, Tetra, Blue Ridge, Nijikawa, API, Aquascape, and more! We even carry Cichlid and Turtle food. Available in soft sticks, pellets, floating, and sinking foods for spring, summer and fall feeding.

Fish Medications

The immune systems in fish can weaken from stress, environmental factors and poor nutrition, making them susceptible to common fish diseases. You'll find all the necessary treatments for these bacterial and parasitic diseases below. The majority of these diseases can be prevented with routine maintenance such as partial water changes, water testing, and of course population control.

Skimmers for Ponds

Most include a leaf basket or net, filter brushes or filter pad(s).

Over the course of a season, your pond will accumulate debris and organics such as leaves, grass clippings, uneaten fish food, and fish waste.
