What does a Pond Aerator do, or why do you need one? A pond that is not properly maintained in most cases has poor quality water. When you see a filthy, dirty, or smelly pond, there is a problem. The cause is due to low oxygen and too much bacteria in the water caused by water run-off and ground water which has a lot of minerals in it. These multiply in the pond with the help from sunlight which causes plant growth in the water.
During a winter kill, these plants die off and sink to the bottom to be decomposed. Decomposition takes oxygen. The oxygen in water does not go down much further than three feet from the surface. That is why some ponds have sludge on the bottom. These plants sink to the bottom partially decomposed and lay there creating an anaerobic (a non-oxygen using) bacteria that further decomposes the plant. By doing this it releases hydrogen sulfide gas and contaminates the water. This anoxic condition is in fact the black smelly water. According to the DNR, aerating your pond is the best treatment. This helps avoid using chemicals which can in turn cause other problems. Let's go natural!
It is a small price to pay for a healthy pond with quality clear water and faster growing fish. To prevent the severity of winter kill and die-off, use a WINGARD AERATOR WINDMILL and start enjoying you pond!
