Pond Aeration

It seems that there are two widely accepted methods to increase oxygen levels in small farm ponds, fountains or bubble aeration systems. However, it seems that the general consensus is that bubble aeration is the best option. This method allows for the deeper water to rise to the surface while adding oxygen to the water. This prevents the surface water from increasing in temperature to the point where algae and duckweed are prolific. In addition, it promotes the growth of bacteria that will actually consume nitrogen, which is often excessive in farm ponds due to nearby farming. This information comes from a variety of web sites. In addition, I received free booklets on farm pond management from the Illinois DNR. For a full list of suggested links and how to obtain the booklets from the DNR, please refer to www.pridge.com.

Fountains and electric aeration systems will require power in order to operate. Assuming that your pond is not too far from a power source, this may not be a problem. However, if power is not an economical option, there are alternatives. I found several companies that offer wind powered compressors that will provide the necessary aeration for smaller ponds. I also identified a company that offers a solar unit.

The cost on these systems range considerably as low as $200 on eBay and as much as $1500 from various suppliers. I will have a complete list of options posted on the Pine Ridge Farm web site www.pridge.com within the next couple days.

I recently acquired a floating fountain, similar to those used in public parks. I realize that this may not provide the best possible oxygenation, but it is difficult to pass up free equipment. It requires 220 VAC which will need to be run down to the pond. I intend to ask an electircian friend of mine to specify the parts list. After the snow melts, and the ground is soft, I will rent a trencher and run the wire down to the pond. Once the basic installation is completed, I will again call on my friend to make the final connections.
