Sub-Surface Aerators

AquaAir® provides ponds and lakes with superior aeration, circulation, and de-stratification. Dissolved oxygen (DO) levels are increased throughout the entire water column with the use of bottom-mounted diffusers. The diffusers employ a super fine micro-bubble technology resulting in the highest diffuser oxygen transfer rates (OTR) available today. The micro-bubbles entrain bottom water and synergistically lift it to the surface where atmospheric oxygen is absorbed and then transferred throughout
the water column.

MasterAquatics have a number of scientific management tools to help in providing improved water quality. One of the most common and beneficial tools is the use of mechanical aeration. Aeration is the mixing process by which you help to add higher levels dissolved oxygen to a given body of water. The two most common methods of providing aeration to a pond or lake is either the installation of floating type fountain or a diffused-air/sub surface aeration system. Of these two mechanical types of aeration, the diffused aeration system is the most effective, flexible and economical process for providing superior water mixing (de-stratification) and increasing dissolved oxygen concentrations in your pond or lake.

Dissolved oxygen concentration is a very important gauge for existing water quality in any lake or pond. A multitude of oxygen consumption is continuously occurring in the water column of any given lake or pond. Fish, bacteria aquatic insects, snail’s, crayfish and other organisms all utilize dissolved oxygen that is present in water. Dissolved oxygen levels are required to be at least 5 mg/L to support most warm water fish and even higher (greater than 7 mg/L) to support a cold water fish populations. Commonly sub-surface aeration equipment can be installed to overcome most oxygen deficiency problems and maintain dissolved oxygen levels to support fish, bacteria and other forms of aquatic life. A properly sized diffused aeration system is most practical in ponds and smaller lakes with water depths greater than 5 feet.

Diffused-air/subsurface aeration can help to significantly improve the water quality and the ecological balance of an aquatic eco-system. There are several positive benefits of proper aeration which include, increased dissolved oxygen levels, prevention of both summer and winter fish kills, reduction of certain nutrient problems, help to increase the decomposition process of organic materials within the pond and de-stratification and ensure mixing of the water column. Generally the end results are a clearer and healthier lake or pond, which can support a more balanced eco-system for aquatic life and their aquatic environment.
