Oxygen is one of the main components in any healthy pond ecosystem. Without adequate oxygen levels, fish will die, and water quality will suffer. If your pond isn’t properly aerated, you’ll see an increase in algae, and muck will form on the bottom of the pond. So, what can you do to raise oxygen levels in your pond?
What is Aeration
Fish and aquatic plants need oxygen to survive. In ponds and lakes with still water, oxygen is absorbed from the air. Absorption only oxygenates the surface of the water. When only the top layer of water is oxygenated, stratification occurs.
Stratification is the formation of layers. In the case of poorly oxygentaed water, the layers with the least amount of dissolved oxygen are closest the the bottom of the pond. These layers are colder than the surface of the water, creating a breeding ground for bacteria. Bacterium feeds on the organic matter at the bottom of the pond, resulting in a rotting, stinking mess.
Aeration circulates the water in a pond while increasing the levels of dissolved oxygen. This improves the health of fish and aquatic plants, reduces algae and bacteria, improves water quality, discourages mosquitoes from breeding and prevents the buildup of foul odors.
Pond aerators and fountains are two of the easiest ways to aerate your lake or pond.
A fountain is a great way to create a relaxing environment and improve the health of your pond. Fountains create movement in otherwise stagnant ponds, but if your pond is more than 6 feet deep, you’ll need to consider an aeration pump to ensure adequate oxygen is reaching the depths of your pond.
Aeration bottom diffusion systems release millions of tiny bubbles into the water. These bubbles rise to the surface, creating movement and ensuring the water is properly oxygenated.
Pond aerators and fountains can be used together to create a healthy and aesthetically pleasing lake or pond. An aquatic management service can address any concern you have about aeration and water quality.
