Moving water in and around your pond is a good thing to do. It adds extra oxygen to the water that would only normally only be oxygenated by plants and surface oxygen absorption. And a fountain can add a great visual element to the water feature.

A pond pump can be used to power a waterfall, a fountain or as part of your pond’s filtration system to remove harmful substances and chemicals. Whilst a pump may not be required for small ponds, if you want any sort of water movement a pump is essential.

The pump is best installed whist you are planning your pond design, especially is you are planning on different levels of ponds so you can move the water between them. If you are planning on using a pond pump for a water feature and also filtration then you may want to consider two different pumps. This will mean you can switch the feature off at night to save electricity and still have the filtration system running.

Pond pumps come in many sizes and you will be amazed at just how much water they are able to move. If used for filtration the should be able to completely filter all the pond water in around 90 minutes, whereas if the are used for a fountain they should be able to provide a stream of water that is more than just a trickle.
Most online pond suppliers and manufacturers offer advice and can help you choose the right sized pond pump for your pond.
