Shallow ponds present unique challenges for aerating but these kits are specifically designed to efficiently and effectively aerate ponds up to 6 and 7 feet deep respectively, and up to about 1/2 to 3/4 acre in size. The key with shallow pond aerators is to pay attention to the maximum depth rating for each system. The aerators use a linear compressor design which is very quiet and very inexpensive to run, but they will not handle the back pressure created from depths greater than six or seven feet. Diaphragm kits are available to keep all of our pumps working well for many years.
The EasyPro systems are well priced for folks on a budget. They perform well as is, but it's helpful to protect the pump from the elements to keep it in better shape. The Airmax SW series is the long-running premium offering in shallow water kits. They include a weather protective cabinet for the pump and all the features you'd expect from a top-of-the-line kit.
