Will aeration stop fish deaths?
Yes. Aeration raises the levels of dissolved oxygen and breaks up stratification.
Does aeration stop algae growth?
It helps, but is not the total answer, aeration will stabilize the temperature of the water, reducing the hot spots in which algae will thrive.
Does aeration stop duck weed or mil-foil?
No, these are aquatics plants, the only way to remove them is to use a herbicide, or employ a fish species that will eat all of the vegetation such as grass carp.
Will aeration eliminate or reduce the foul smell in the pond?
Yes. Odors are common in ponds that aren’t aerated.
In the summer and winter, non-aerated ponds stratify into layers of water with distinct temperature differences. The bottom layers are essentially trapped down there and the oxygen level is used up. Slow-moving bacteria use enzymes to ferment and digest decaying muck at the bottom of a pond. These microorganisms eventually produce waste products, including carbon dioxide and hydrogen sulfide. This is where that sulfur and rotten egg smell comes from. This is one of our more popular and frequently asked questions.
Can you have too much aeration?
Does aeration help cultured bacteria added to pond water?
Yes. Water displacement from the expulsion of bubbles can cause a mixing action to occur.
Will aeration clear tinted water ( tinted by leaves or decaying organic material)?
In winter will aeration keep fish alive?
Yes, even when the pond is frozen over the aerator will continuously provide oxygen to sustain the fish. Often, use of aeration keeps ponds from becoming completely frozen over.
Why Is Dissolved Oxygen So Important?
Dissolved oxygen analysis measures the amount of gaseous oxygen (O2) dissolved in an aqueous solution. Oxygen gets into water by diffusion from the surrounding air, by aeration (rapid movement), and as a waste product of photosynthesis.
Like terrestrial animals, fish and other aquatic organisms need oxygen to live. As water moves past their gills (or other breathing apparatus), microscopic bubbles of oxygen gas in the water, called dissolved oxygen (DO), are transferred from the water to their blood. Like any other gas diffusion process, the transfer is efficient only above certain concentrations. In other words, oxygen can be present in the water, but at too low a concentration to sustain aquatic life. Oxygen also is needed by virtually all algae and all macrophytes, and for many chemical and biological reactions that are important to lake functioning.
What is the Environmental Impact?
Adequate dissolved oxygen is necessary for good water quality. Oxygen is a necessary element to all forms of life. Natural stream purification processes require adequate oxygen levels in order to provide for aerobic life forms. As dissolved oxygen levels in water drop below 5.0 mg/l, aquatic life is put under stress. The lower the concentration, the greater the stress. Oxygen levels that remain below 1-2 mg/l for a few hours can result in large fish kills.
What are the Reasons for Natural Variation?
Oxygen is produced during photosynthesis and consumed during respiration and decomposition. Because it requires light, photosynthesis occurs only during daylight hours. Respiration and decomposition, on the other hand, occur 24 hours a day. This difference alone can account for large daily variations in Dissolved Oxygen concentrations. During the night, when photosynthesis cannot counterbalance the loss of oxygen through respiration and decomposition, Dissolved Oxygen concentration may steadily decline.It is lowest just before dawn, when photosynthesis resumes.
Other sources of oxygen include the air and inflowing streams. Oxygen concentrations are much higher in air, which is about 21% oxygen, than in water, which is a tiny fraction of 1 percent oxygen. Where the air and water meet, this tremendous difference in concentration causes oxygen molecules in the air to dissolve into the water. More oxygen dissolves into water when wind stirs the water; as the waves create more surface area, more diffusion can occur. A similar process happens when you add sugar to a cup of coffee the sugar dissolves. It dissolves more quickly, however, when you stir the coffee.
Another physical process that affects Dissolved Oxygen concentrations isthe relationship between water temperature and gas saturation. Cold water can hold more of any gas, in this case oxygen, than warmer water. Warmer water becomes saturated more easily with oxygen. As water becomes warmer it can hold less and less Dissolved Oxygen. So, during the summer months in the warmer top portion of a lake, the total amount of oxygen present may be limited by temperature. If the water becomes too warm, even if 100% saturated, O2 levels may be sub optimal for many species of trout.
Mid-summer, when strong thermal stratification develops in a lake, may be a very hard time for fish. Water near the surface of the lake the epilimnion -is too warm for them, while the water near the bottom the hypolimnion has too little oxygen. Conditions may become especially serious during a spate of hot, calm weather, resulting in the loss of many fish. You may have heard about summertime fish kills in local lakes that likely results from this problem.
Dissolved Oxygen concentrations may change dramatically with lake depth. Oxygen production occurs in the top portion of a lake, where sunlight drives the engines of photosynthesis. Oxygen consumption is greatest near the bottom of a lake, where sunken organic matter accumulates and decomposes. In deeper, stratified, lakes, this difference may be dramatic plenty of oxygen near the top but practically none near the bottom. If the lake is shallow and easily mixed by wind, the Dissolved Oxygen concentration may be fairly consistent throughout the water column as long as it is windy. When calm,a pronounced decline with depth may be observed.
Seasonal changes also affect Dissolved Oxygen concentrations. Warmer temperatures during summer speed up the rates of photosynthesis and decomposition. When all the plants die at the end of the growing season,their decomposition results in heavy oxygen consumption. Other seasonal events, such as changes in lake water levels, volume of inflows and outflows, and presence of ice cover, also cause natural variation in Dissolved Oxygen concentrations.
What is the Expected Impact of Pollution?
To the degree that pollution contributes oxygen-demanding organic matter (like sewage, lawn clippings, soils from stream bank and lakeshore erosion, and from agricultural runoff) or nutrients that stimulate growth of organic matter, pollution causes a decrease in average Dissolved Oxygen concentrations. If the organic matter is formed in the lake, for example by algal growth, at least some oxygen is produced during growth to offset the eventual loss of oxygen during decomposition. However, in lakes where a large portion of the organic matter is brought in from outside the lake, oxygen production and oxygen consumption are not balanced and low Dissolved Oxygen may become even more of a problem.
The development of anoxia in lakes is most pronounced in thermally stratified systems in summer and under the ice in winter when the water mass is cut-off from the atmosphere. Besides the direct effects on aerobic organisms, anoxia can lead to increased release of phosphorus from sediments that can fuel algal blooms when mixed into the upper euphoric (sunlit) zone. It also leads to the buildup of chemically reduced compounds such as ammonium and hydrogen sulfide (H2S, rotten egg gas) which can be toxic to bottom dwelling organisms. In extreme cases, sudden mixing of H2S into the upper water column can cause fish kills.
