Introduction to Pond Aerators

Aeration is one of the most crucial things in keeping a wholesome pond. Backyard ponds, no matter how big or small, need air to keep aquatic and plant inhabitants alive, and also to clean the water. Aerators ensure that no matter what you set in your pond, or that which sneaks in when you are not looking, there’s enough oxygen to keep it healthy and odor-free.

Oxygen and Ponds

Dissolved oxygen refers to the amount of oxygen available to plants and aquatic creatures in your pond water. Ponds require a minimum oxygen level of 5 parts per thousand. Lower oxygen levels can kill fish, and lead to toxic scents because the breakdown of organic wastes is altered as a result of the lack of air necessary to carry out the aerobic process, producing hydrogen sulfide. In deep ponds, a lack of oxygen also leads to stratification, which can be when an extremely oxygen-deficient layer forms in the bottom of your pond. This layer reduces the amount of oxygenated water available for plants and fish.

Ponds Without Aerators

Ponds which don’t utilize an aerator are inclined to be low in dissolved oxygen. There are several things which can reduce the levels of oxygen in your pond water, however, the most common reason is a lot of aquatic plants, especially algae. Plants are good for your pond because they release oxygen throughout the day. Planktonic algae are also favorable because they form the basis of the pond’s food chain. However, while a lot of these plants release oxygen through the day, they also have it in night. In case you have an excessive amount of vegetation, the crops may have any oxygen they may have contributed through the day every evening. Organic waste in decaying vegetation, runoff from natural fertilizers, fish food, and fish or other animal wastes also utilize oxygen to decompose. Aerators are necessary to ensure your pond has enough oxygen to break these materials down, and sustain any aquatic life it contains.

Surface Aerators

Shallow ponds which are less than 6 feet deep are perfect for surface aerators. This sort of aerator typically contains aeration units which float on your own pond. They function using air-to-water contact to transfer oxygen. The floating pump unit draws water in the top 1 to 2 feet of pond water and splashes or sprays it to the air. As the water flow into the pond, oxygen transfer and the venting of gases happens. Surface aerators contain fountain and paddle-wheel designs. They just function well for shallow slopes because the oxygen transfer is taking place only at the surface. Surface aerators can be found with different spray patterns, however, the more powerful or surplus the spray, the less efficient those aerators are inclined to be in their aeration.

Diffused Aerators

Diffused aerators are usually utilised in deep slopes, and work with the help of a compressor that is installed on coast. The compressor pumps air into the pond through a hose that’s attached to an underwater unit. The submerged unit is attached to diffusers. Diffused aerators push air down to the bottom of the pond, creating bubbles. These bubbles naturally rise to the surface, and as they rise, the bubbles destratify the water, which removes the low oxygen layer in the bottom, mixing it with the oxygen-rich water at the peak of the pond. Diffused aerators create only a tiny amount of surface agitation, which you may find more visually appealing compared to the surface unit.
