How to Install a Filter in a Garden Pond

By Regina Sass ; Updated September 21, 2017
Keep the pond clean for the health of the fish and the plants.

Know the details about your pond before setting out to purchase one. The size of the pond, whether it has plants, fish or both and whether it is in a sunny location all are determining factors. Write down all of the facts and bring them with you so the salesperson knows exactly what you need.

Pick a submerged filter for small- or medium-size ponds and an external filter for a large pond.

Connect the filter to the pump with a hose with threaded connectors.

Tighten the connectors by hand so they will be easy to undo when the pump, hoses or filter needs a cleaning.

Put the hose that exits the filter at the bottom of the pond or attach it to a floating fountain or waterfall.

Place an external filter on a solid, flat surface.

Pick a place in a spot in the pond where a submerged filter is less likely to come in contact with falling leaves and other debris.

Plug the filter into a ground fault circuit interrupter. It will automatically shut down in case of a short circuit.
