Do I Need a Pump in My Garden Pond?


A garden pond can be a beautiful and soothing element in any garden or yard, but there are a few things required for a garden pond. A pump is the most important part of a garden pond. Whether you have fish in your garden pond or it simply provides a habitat for frogs and other wildlife, your pond needs a pump.


A pump works by circulating water throughout the pond. That circulation aerates the water and provides oxygen, which is necessary for a healthy pond. The oxygen is necessary for the life and health of fish and other beneficial bacteria that live in the pond.

Water Circulation

Even if you don't plan to include fish in your garden pond, aeration and filtration is important to plants and beneficial insects that will visit. Without some type of circulation, the water will stagnate, which you don't want. Stagnant water also develops a murky appearance and an unpleasant odor that does not fit well with a beautiful garden.

Insect Control

The water in your garden pond will attract a number of insects, the most undesirable being the pesky mosquito. Circulating water cuts down on mosquito infestations as mosquitoes prefer stagnant water for breeding. A pond pump coupled with a fountain or a waterfall is an attractive display that should provide enough movement of the water to deter mosquitoes.

Attracts Wildlife

The sound of running water attracts wildlife, such as hummingbirds, wild birds, butterflies and frogs. Stagnant water, on the other hand, attracts unwanted visitors and odors. A pond pump provides the necessary circulation.

Control of Algae

A properly functioning pond pump will help keep algae levels manageable in a garden pond. While some algae is beneficial to a garden pond, too much algae can overtake the pond and choke out plants while hindering the oxygen needed by fish. The circulation and water movement provided by a pond pump can keep the algae at a level that is beneficial to your pond.
