When choosing a pump, whether it be a Submersible Pump or a Dry Surface Pump be sure that the pump that you are thinking about buying will do the job properly... for example: If your pond has 5,000 gallons capacity then you need a pump that will deliver 2,500 gph (half the capacity of your pond) so that the water in your pond turns over once every 2 hours ... but Please bear in mind that you will have restrictions in the pipework that will, in some cases, dramatically reduce the output flow to your pond, for example: Ultra Violet Clarifiers - length of pipework runs - how many bends you have fitted etc ..etc... If you are not sure what we mean then please email us, or telephone Trevor and it will be explained to you... Also bear in mind that at sometime in the future you may wish to add to your pond, and, or your equipment - for example; adding a heating unit (a very good idea anyway) or may wish to power up to a new waterfall... there are many factors to be taken into account when selecting your pump...
