In order to oxygenate your pond, you will need to use a pond aerator such as a fountain aerator. This is essential if you want a healthy pond or lake regardless of the season. In summer or winter, a fountain aerator is needed to provide oxygen within the pond. During colder weather, a fountain aerator supplies water movement at the surface to prevent the top of the pond from freezing. This will allow oxygen to flow through the hole and provide a means for toxic gases from decomposing organic matter in the pond to escape. In addition to the basic function, a fountain aerator will also add aesthetically to your pond. If you are in the market for a fountain aerator, please browse our selection of aerators.
