Aeration Systems for Large Lakes to Small Ponds
A great need for oxygen exists at the bottom of a eutrophic (nutrient-rich) body of fresh water. Oxygen is available at the surface but fails to reach the lake bottom due to thermal stratification, poor circulation and/or rapid consumption. This is especially so during the summer months, when the water is warm. Under these conditions, oxygen can be consumed faster than it can be replenished, killing aquatic animals in the lower levels that are unable to migrate up.
Without bottom oxygen, a lake or pond’s self-purification capability is significantly diminished. Nutrients that are normally held in the sediment get cycled into the water column in a dynamic called “nutrient cycling.” These excess nutrients are just as harmful to the lake as those that come from the surrounding watershed, such as fertilizers, animal droppings and septic tank seepage and nutrients recycled from the sediment all increase the need for oxygen.
Whether you maintain a koi pond, farm pond, park lake or drinking water reservoir, Aquatic Eco-Systems has the aeration system needed to keep your oxygen levels high and your algae growth low. All of our systems are designed to run continuously, maximizing efficiency to save you money.
For lakes, choose one of our Great Lakes® aeration systems. These systems have improved lakes of all sizes around the world. Shallow aquaculture ponds may be aerated using a FAT CAT™ system to achieve the best possible results. For koi ponds containing up to 200 pounds of fish, choose one of our small pond aeration systems.
Floating Aeration Technique for Continuous Aquatic Turnover “8,000 pounds of fish with just 2 horsepower!”
Continuous aeration benefits your pond in a number of ways:
It can reduce or eliminate the need for emergency aeration and water exchange; it can reduce the build up of ammonia, blue-green algae and muck; and it helps to keep oxygen near the bottom, where it can keep benthic organisms alive. FAT CAT™–a series of small diffusers tied to one or more floating air lines and driven by a low pressure, low-maintenance air blower. It’s simple, efficient, inexpensive to purchase and maintain, and has no propellers, paddles or electricity to damage the fish.
There are a number of ways to aerate shallow aquaculture ponds but, honestly, we know of no other method that works as well or as cost effectively as the FAT CAT™ for small ponds to one acre.
A large area of influence & easy removal for seining.
The FAT CAT™ method uses between 1/2 and 2 horsepower per surface acre. It uses numerous small diffusers–far more effective than a few large ones because the aeration is more uniform. And, because the diffusers are suspended from an air line, they are easily moved to the shore for seining. The technique works especially well for small ponds, such as those used for raising tropical fish and prawns, for quarantine and research purposes and for nursery ponds from 1/2″ acre.
Maintain a crop, NOT equipment.
In areas of soft water, the FAT CAT™ diffusers will need cleaning only about once a year; in hard water, up to four times per year. Other than periodic diffuser cleaning, the FAT CAT™ runs maintenance free. Another beauty of the design is its simplicity. For example, there are no valves to control the flow of air to the diffusers! Using as little as 2 horsepower of electricity per surface acre of a shallow pond, the FAT CAT™ can maintain a crop of 8,000 pounds of catfish! As efficient as the FAT CAT™ is, it’s important to note that it is not an emergency aeration system (the low-horsepower design is for continuous operation). At high stocking densities, emergency aeration may still be required.
