Small pond aerators, also called pond bubblers, circulate water to limit harmful gas buildup and promote healthy oxygen levels, maintaining a balanced ecosystem. They can also be used in the winter months to keep a hole open in the ice for fish and aquatic plants. A pond will deteriorate if it does not have enough pond aeration with proper pond aerators to raise the dissolved oxygen level to meet the demand of the plants, fishes, and other organisms in the pond especially those located on the bottom. As soon as the pond deteriorates, stratification will occur and sludge and debris will start to settle on the bottom of the pond which will produce toxic gases. These gases make it difficult for the organisms in the pond to survive especially the fishes and other bottom dwelling organisms that help keep the pond clean. The fishes as well as the bottom dwellers will be prone to diseases or even death. This loss greatly reduces the ability of the pond to clean itself. In order to oxygenate or introduce oxygen into a pond, a pond aerator is needed. Pond aeration provides the pond with the required oxygen content for the fish, plants, and other organisms to survive and live in the water. Pond aerators also help eliminate stratification of the pond water. Pond aerators are quiet, reliable, as well as efficient. During hot weather conditions, a pond aerator can provide the needed oxygen in the pond. During winter conditions, a pond aerator does not only provide oxygen to the pond but it also creates water movement on the surface of the pond by means of the pond aerator pump which keeps that area of the pond from freezing. Through this opening in the ice, fresh oxygen can come into the pond while toxic gases from the decomposition of decayed organisms can escape.
