Choosing the correct aeration delivery system for your lake or pond is one of the most important decisions you will make for the long-term health and balance of your waterbody. Regardless of how big or small your waterbody is, the goal of an aeration system is to evenly spread an adequate amount of dissolved oxygen throughout the entire water column. Lakes and ponds naturally receive dissolved oxygen from several sources, most notably plant respiration and atmospheric surface mixing. This input of oxygen should be equal to or greater than the demand of the aquatic ecosystem. The entire ecosystem of the water needs that dissolved oxygen, whether at the very bottom of the food chain for microbial decomposition, or at the top for largemouth bass and other predator fish. In most cases, it is discovered that the oxygen supply is lacking due to pond nutrient pollution or other stresses caused by people and land development.
To determine what type of oxygen delivery method or aeration system is appropriate, the waterbody needs to be looked at from several angles. Many online resources recommend aeration systems based on only one or two aspects of the waterbody. To find the best aeration solution, several factors should be considered: 1) overall acreage of the lake or pond, 2) average water depth, 3) maximum water depth, 4) shape of the waterbody, 5) proximity to electricity, 6) desired aesthetics, 7) noise tolerance, 8) water quality. The more information we have, the better we can determine how to spread the dissolved oxygen throughout the entire lake or pond.
