Pond pumps are essential in garden ponds in order to preserve its cleanliness plus the wellness of fish and other inhabitants. A pond pump is generally put to use together with a filtration system to help protect against deposits of dirt and grime inside your pond. The filtration may also help preserve the waters pH balance to sustain a wholesome habitat.

A pond pump can typically be made use of to build water features, water sprays or other water features. In addition, pumps keep moving water oxygenated, which is vital for the survival of fish and other pond inhabitants.

Buying the right pond pump

A pond pump should ideally circulate the total volume every hour but once every two hours would suffice as an absolute minimum. To calculate the volume of your pond you should multiply the surface area (in square metres ) of your pond by the average depth (in metres ), which will give the pond volume in cubic metres. Every cubic metre of pond volume will contain approximately 220 imperial gallons of water. So, a pond of 15 cubic metres will contain approximately 3,300 gallons of water. From this figure, you can determine the flow rate needed for the proper circulation of the water.

There are, however a number other variables involved that can affect flow rates such as the length and diameter of the pipework, the number of bends and tightness of each, type of filter used and whether a fountain is being run off the same pump. With so many possible variables, it is advisable to go for a pump that gives a higher flow rate than you think you need as the flow rate can always be restricted to reduce it, but you cannot increase flow rates above the pumps maximum output.
