What size pump is most suitable for garden ponds?
If you need a pump to operate a filter, the size pump you use in your pond will depend on the volume of water that needs to be moved. This, in turn, will depend on the size of your pond. However, you can use a relatively small submersible pump in a large pond if you simply want to create a fountain feature. For fountains, it is the water head or height that the water will spurt that is important.
