Pond and lakes are a valuable natural resource. They add to the beauty of the landscape, provide recreation, are a habitat for fish and wildlife and an additional water source if needed. However, the good health of a pond is held in a delicate balance. A ponds condition deteriorates when the bottom environment cannot support animal life. The bottom is the area that runs out of oxygen first, it is where the most oxygen is used and it is the farthest from the surface where it is replenished. Without oxygen a lake or ponds self purification capability is not only reduced, it is reversed. The small animals, snails, worms, bacteria, etc., which help keep a pond clean cannot live and the ponds nutrients are then recycled from the sediment. This forms a layer of muck at the bottom which serves as a fertilizer for weed and excessive algae growth. It could also cause large fish kills.
The way to prevent this from ever happening is through the use of bottom aeration and bacteria. This can be accomplished by the use of a diffuser system which can move as much as 2-4,000 gallons of water per minute containing thousands of air bubbles, each containing oxygen from the bottom of the pond to the top. This exposes the bottom layer to the atmosphere and destratifying the pond or lake. Each pond or lakes needs can be different. Following is a look at different methods.
Linear Air Compressor
They are extremely energy efficient. The largest model only drawing 80 watts. They are super quiet and low maintenance, thirty five thousands hours of continuous service before replacing the diaphragm and valves. The covers are weatherproof and can be left out without protection. They are effective in aerating a pond to a depth of 12 feet.
Diaphragm compressors are for aerating deeper ponds to a depth of 35'. Because of their high pressure the compressors can be located up to 2,000 " from the pond and still operate successfully. It's built for years of continuous service with only occasional air filter cleaning and an eventual diaphragm replacement. They draw approximately 3.5 AMPS and are not weatherproof and must be covered.
Rotary Vane Compressors
Rotary vane compressors can aerate large ponds and small lakes. They can aerate to a depth of 27' with the high pressure model. The carbon vanes self adjust for years of maximum efficiency and can be easily replaced when needed. They draw between 5 and 7 amps and must be protected from the weather.

Each of the above compressors send air through tubing to air diffuser manifolds which rest on the bottom of the pond or lake in a special container. The only maintenance is an occasional cleaning of the air diffusers.
We have used every compressor mentioned at our fish hatchery and have sold and installed successfully many of the above. There is no better pond or lake aeration system available. We use and sell only Alita and Gast compressors which we believe are the best in the industry.
We are available for pond and lake aeration consultation and pricing as each pond and lakes needs may be different.
