Pond Fountains can reduce pond sediment and sludge
One of the great benefits of pond aeration is reducing pond sediment. This pond sediment or
muck is made up of a layer of natural organic material can quickly decrease the depth of your
When faced with a large build up of this sediment, a pond owner can opt to have it removed by dredging.
While this is a quick solutiuon, the process is often costly to both implement and to dispose of this layer of
sediment. The overall cost and the reality that this is a solution that will need to be performed every
several years often precludes it from being used by many pond owners
Another method of removing this layer of muck is to add biologic agents to eat the muck. These biological
agents or microbes are once again costly and must be employed continually to ensure that the sediment buildup does
not occur. Furthermore, as with any ecosystem, one must consider the ramifications on the overall pond
While installing a pond fountain will not provide instant sediment removal, over time the layer of sediment that
makes up the bottom of the pond will begin to decrease and the pond should show an overall improvement in
clarity. This improvement can be quantiified simply by taking measurements of the depth of the sediment layer
at certain points throughout the pond and comparing these every 6 months to a year to determine the overall
improvement. Additionally the clarity of the water can be measured by submerging an object into the
water at a few locations and measuring how deep the object can be sunk before it can no longer be seen.
Pond fountains have been proven to help inhibit the growth of the sediment layer by promoting aerobic activity
in the pond. Sediment layers have been shown to reduce up to 9 inches or more in one year with use of a
pond aeration system. With continous use of the fountain, which continually turns over the pond and brings the
lower areas of the pond to the surface to be well aerated, over time a pond will slowly become a healthier habitat
for aquatic life and the anaerobic material that forms along the pond bottom will lessen. The effect will be
a healthier and clearer pond.
