The heart of the ecosystem. The pump circulates the water from the skimmer pulling it through the filter mats and sending it over to the bottom of the biofalls where it passes up through another set of filter mats and media. In the pond kits, pumps are sized to turn over all the pond water in one hour.
Choosing a pump for a water garden should be based on a few job requirements. Desired flow, pumping height and electrical costs are all factors that need to be considered. The higher a pump needs to push water, the less flow you are going to get out of that pump. The pond kits come with pumps sized to turn a pond over at least once an hour. If pumping height is close to maximum pump shut-off height, substitute the next larger pump available. High efficiency pumps are higher quality, will last longer, and use less electricity. If project budget constraints are a concern, use a less expensive low efficiency pump. Pumps should be run 24 hours a day, 7 days a week to keep the ecosystem functioning properly. |
