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. Great Lakes™ Deep Aeration System Aeration » Aeration Systems » The Great Lakes™ aeration/destratification system is guaranteed to be the lowest cost method of inducing circulation to remove stratification, add oxygen and deliver the many benefits that result from sufficient bottom oxygen. These systems feature Sweetwater ® synergistic air lift diffusers that have proven their effectiveness in over 250,000 acres of lakes worldwide. Install a Great Lakes™ system and be confident that you have the most efficient and effective system available. We have more experience than anybody. For system sizing see the Average Sizing Guides below, then contact our Lakes Department for assistance before ordering. One-year warranty. Installation available. For deep lakes: Compressors are factory wired for either 115V or 230V single-phase. Three-phase models, not wired, are also available. Deep lake systems use our ALA6GL diffuser manifold(s) intended for lakes deeper than 8'. The compressors can be mounted in an optional vandalproof, lockable cabinet that will also keep out the weather. The cabinet is made of 1/8" thick steel and painted avocado green to blend into the surrounding landscape. Cabinets include built-in cooling fan(s), lock(s) and soundproofing that keeps the noise level below 55 dB (normal conversation) at 10' and virtually inaudible at 50'. Cabinets come mounted on a lightweight equipment pad that is suitable for private installations. The cabinet can be bolted to a concrete base (for public installations). Tubing sold separately due to the variation in lake sizes. Choose either a 100' (P200S) or 400' (P200) roll of unweighted tubing on land. If used in the lake, the unweighted tubing requires tie wraps (T120R) and three-hole bricks (purchased locally) placed every 5-8' to weigh it down. Self-weighted tubing (WD1R) requires no weights, so it takes much less time to install. Both types of tubing can be connected using couplings (101A) and clamps (use SSA for P200 tubing and SSB for WD1R tubing). One coupling and two clamps per connection will be needed. Cabinets can be located a long distance from the lake shore (ask the Lakes Department for guidance with this).
