External Pond Pumps
External Pond Pumps are ideal for medium to larger pond sizes. For
example: a pond that consitst of 1000 gallons of water or more is a
good candidate for one. This type of pond pump is especially effective
for larger ponds because it is energy efficient. The cost of using a
submersible pump in a large pond can be much higher. Also, external
pumps can handle larger water flows. And an even further benefit of
this type of pump for a large pond is that it works well with
biological filters.
