Planning a Garden Pond

A pond can create a beautiful focal point in your garden. Even in the smallest space, a pond can help you create an oasis within the confines of your back yard. Whether it houses fish or just plants, it can add to the ambience and appeal of your home.

Before you begin, think about the size of your pond. Calculate the volume by using the following:

Length x width x depth = volume.

The volume denotes the capacity of the pond pump and filter needed. The larger the pond, the higher capacity the equipment and possibly more expensive. This also tells you how big the pond liner needs to be. Working out these costs beforehand allows you to adjust your budget (or plans!), accordingly.

Pond Pump and Filter

These are important pieces of pond equipment. A filter is essential to cleanse the water of debris and pollutants to keep the water in perfect condition. Many filters now come complete with media and even UV light to cleanse algae cells from the water. For a larger pond or one with lots of fish, an external pump and filter can be the best idea and save space in your pond. Swell UK has a wide variety of pond filters and pumps for every type of pond.

A pond pump moves the water around and sends it to filter for cleaning. Good circulation is vital for oxygen dissemination and good water conditions. If you have a smaller pond, a solar pump can be a great cost effective way to keep the water moving without any running costs.

Location and Excavation

Decide where you will place the pond. It must be a flat and even surface, to avoid flooding and create a balanced finish. A spot with some shade but lots of sun is ideal. Too much sun and algae can be a problem, too much shade can mean that fish and plants suffer, so aim for a balance.

Dig out the area needed. Stick to an easy shape if you are a novice, but a good tip is to dig out shelves in the sides of the pond. This creates good levels for plants to sit on and create a very natural effect.

Remove any sharp stones and debris from the floor of the pond. This will ensure that the underlay and liner have the best foundation. Choose the best underlay and liner that you can afford. This will create the best firm base and provide years of top performance.

Push the liner into place in stockinged feet. This allows you to force the liner into every crack and crevice for the best finish. Once you are satisfied, add a little water to weigh down the liner. Around the edges, trim the liner and place stones, rocks or railway sleepers around the edge to create a useful yet attractive border. You can now fill the pond slowly.


Plants can be added in plant baskets onto the ledges you created. Use a good liner and pond soil to create a good foundation for the plants. Special aquatic soil is a must as it does not disintegrate in the water. Use a variety of plants to create a naturalistic effect and build up a rich, luxurious effect.

A fountain can be the crowning glory in your pond. Many pumps come complete with a fountain attachment so for little extra cost you can add an elegant touch. A fountain also contributes to the aeration of the water as it circulates around the pond.

Lights can add even more elegance. There are many different types available from submerged lights to more structured designs that sit around the pond. Many fountains now come complete with LED lights incorporated into the unit too, so you can create the ultimate water feature.
