LAKE & POND AERATORS
For most ponds, oxygen production is limited to wind diffusion, wave action and photosynthesis, which often leads to dangerously low dissolved oxygen levels, thermal stratification and stagnation. Dissolved oxygen may fall below life sustaining levels (5 ppm) for a variety of reasons during The Summer Oxygen Cycle and your pond may suffer a fish kill. An aeration system for your lake or pond allows you to supplement the actions of nature by adding a dependable supply of diffused oxygen. Think of it as an insurance policy for your fish. In addition to providing increased oxygen levels for your fish, aerators also help circulate the water in your lake or pond, vents off harmful gases and helps provide extra oxygen for beneficial bacteria to help decompose all of the organic material like grass clippings, leaves, dead aquatic plants and animal waste that accumulates at the bottom of your pond. Without oxygen, these bacteria simply can’t break down the organic wastes efficiently so they just keep adding to the muck on the bottom of your pond where they act as fertilizer for unwanted algae and aquatic weed growth. The many Benefits of Aeration make it the single best thing you can do for your pond. There are multiple variations to choose from, but there are basically only two types of lake and pond aeration systems: surface and sub-surface. The average depth of your pond will determine which one is best for you. If it’s less than 5 feet, a surface aerator will probably work best, while deeper ponds will benefit more from a sub-surface aeration system.
Sub-surface, or diffused, aeration has the unique ability to create what is known as an airlift current from the bottom of the pond to the top, while at the same time introducing oxygen to the water column through millions of tiny air bubbles that originate from self-cleaning flexible membrane diffusers anchored on the bottom of the pond. This aerates the pond through the most economical and efficient method: de-stratification. These systems can lift the maximum amount of water from the bottom to the surface using the least amount of energy and are the best form of aeration for most ponds.
Surface aerators are floating pump units that pull water in from the top 2-3 feet of the pond and splash it into the air. As the water crashes back down onto the surface, oxygen transfer occurs along with the venting of harmful gases. Since the oxygen transfer is taking place just at the surface, these aeration systems are best suited for shallower ponds. Because of the high circulation rate, these pond aerators are especially helpful in controlling surface algae and other unsightly surface problems.
Solar aeration systems utilize the sun’s energy to add oxygen to your pond. The solar panels convert photons from sunlight into usable energy, which is then used to power a highly efficient air compressor. Solar aeration systems are great for environmentally conscience applications and remote installations where extending electrical service is cost prohibitive. The AerMaster line of affordable, high efficiency solar aeration systems have eliminated the expense of rechargeable batteries and charge controllers by utilizing a direct drive mode of operation that also reduces the cost of maintaining additional components.
Windmill aeration systems are a good option for remote ponds that are so far from a source of power that extending electrical service is not economically feasible. These systems come with three and four legged 12′-24′ towers in wood, galvanized metal, or powder coated metal, a compressor assembly, airline and membrane diffusers. They can be placed up to 1000′ away from the pond’s edge, which is critical for those ponds that are in low areas or surrounded by trees. The large (6′) fan blades allow the compressor to aerate in as little as 3-5 mph winds.
We realize that some budgets simply do not allow for the additional costs associated with aeration systems with cabinets. These lower priced sub-surface aeration systems were developed for do-it-yourself installation and require that the compressor be sheltered from the weather in an existing shed, garage or boathouse. We offer three different packages that include a ¼, ½ or ¾ hp compressor, valves, diffusers and tubing. They achieve about the same results, at a lower initial cost.
