Depending on the system type, solar and wind-powered lake aeration systems offer a green alternative to electric systems.
Aeration moves air and water in a lake, bringing natural benefits to all lake areas. An adequately designed bottom-diffused aeration system allows most of your lake to contact the atmosphere, releasing toxic gasses and replenishing oxygen.
Improves Water Quality
Aeration helps improve the water quality of your lake or pond by stabilizing pH levels, reducing alkalinity, removing carbon dioxide, and oxygenating your water body. It also allows aerobic bacteria to break down organic waste, which reduces the amount of nutrient-fuelled algae.
The oxygen-rich environment created by aeration is particularly beneficial for warm-water fish like trout. These fish struggle in low-oxygen environments. Oxygen-rich conditions make them healthier and allow for fewer fish kills.
Diffused aeration prevents stratification throughout the year, so the entire aquatic habitat receives oxygen. This also prevents fish kills from low oxygen under the ice during winter. It also creates open water areas that help to reduce the risk of ice damage and allows for a safer place for recreational activity.
Increases Fish Counts
As the water in a lake or pond circulates, it becomes exposed to oxygen from the atmosphere and other sources. This helps increase the amount of dissolved oxygen in the water and improves the conditions for fish to thrive.
When lakes become stagnant, the muck and organic materials on the bottom accumulate and cause low dissolved oxygen levels (DO). These conditions fuel nuisance algae, foul odors, toxic weeds, and other problems that degrade water quality.
Lake aeration helps break up these sediment layers and increases the water circulation in the lake or pond, improving the living environment for warm water fish. It also reduces the formation of hydrogen sulfide gas, which can result from foul odors in stagnant conditions. It also allows for converting phosphorus in the water to forms that algae cannot use as food, further mitigating water quality issues.
Prevents Stratification
In the summer, lakes can become layered with different temperatures due to sun exposure. The warmer water on top is less dense than the cooler bottom layer, preventing the layers from mixing naturally. This process is known as stratification. Diffused aeration prevents stratification by circulating the lake water to ensure oxygen is evenly distributed throughout the water column.
Air injection systems use a compressor on shore to blow air into the lake via perforated tubes or diffusers. This causes the colder hypolimnion (bottom) water to rise, pulling it into the warmer epilimnion where it is mixed with the other lake water and oxygenated. This also reduces the accumulation of harmful hydrogen sulfide gas. Aeration also helps to bind phosphorus in the sediments, making it unavailable for algae growth.
Reduces Mosquitoes
Regular pond management, floating fountains, and diffused air aeration systems (bubblers) allow water to be constantly agitated, disrupting mosquitoes’ breeding habitat. Additionally, the bacteria Bti (Bacillus thuringiensis subspecies israelensis) present in these systems produces a toxin that kills mosquito larvae.
Aeration promotes healthier aquatic plants and fish by distributing oxygen throughout the lake or pond. This reduces algae blooms that fuel murky waters and harmful toxins in the ecosystem.
The constant agitation of aeration also promotes the natural decomposition of debris and dead organisms in the water, eliminating pond odors. This prevents the build-up of muck and toxic ammonia and nitrites, which is essential for fish health. It also prevents low oxygen levels from forming, which is common in stagnant water.
Prevents Fish Kills
The winter water aeration process agitates and mixes the waters to prevent stratification, reducing layers devoid of oxygen which can be a significant concern for fish. When dissolved oxygen levels drop, algae and plants cannot grow, which can stress or kill fish under the ice. Aeration circulates oxygen throughout the lake, preventing this stress and eliminating fish kills under the ice.
Diffused aeration also helps to convert phosphorus into forms that algae can’t use, decreasing the amount of toxic, harmful blue-green algae blooms and improving water quality. It also helps to reduce the amount of hydrogen sulfide gas that can create foul odors in stagnant, dead aquatic vegetation.
