Kasco Surface Aerators

Kasco Surface Aerators

High-Efficiency Floating Surface Aeration Systems Designed to Maximise Oxygen Transfer, Improve Water Circulation, Eliminate Stratification, and Maintain a Healthy, Balanced Aquatic Ecosystem in Ponds and Lakes

Kasco Surface Aerators are high-performance aquatic aeration systems engineered to dramatically improve water quality by continuously moving large volumes of water from below the surface into the air. This process significantly enhances oxygen transfer, improves circulation, and maintains a uniform water column throughout ponds, lakes, and other large aquatic environments.

Designed for reliability and long-term operation, these aerators actively combat the most common water quality issues found in stagnant or poorly circulated systems. By continuously agitating the surface and drawing deeper water upward, Kasco Surface Aerators help prevent thermal stratification, where layers of water at different temperatures and oxygen levels form and remain isolated. This stratification is a leading cause of poor water quality, low oxygen levels, and fish stress or mortality in warm seasons.

The powerful aeration process introduces high levels of dissolved oxygen into the water, supporting fish health, enhancing beneficial bacterial activity, and accelerating the natural breakdown of organic waste such as sludge, fish waste, and decaying vegetation. As oxygen levels increase and circulation improves, odour-causing anaerobic conditions are reduced, resulting in a cleaner, fresher, and more stable aquatic environment.

Kasco Surface Aerators are widely recognised for their efficiency and dependability, delivering up to 3.0 lbs of oxygen per horsepower per hour of operation. This makes them one of the most effective surface aeration solutions available for both commercial and residential pond management applications.

Engineered for ease of use, these self-contained units are designed for straightforward installation and can typically be deployed by a single operator. Their durable floating design allows them to operate effectively in shallow water conditions as low as 45 cm, making them suitable for a wide range of pond and lake environments.

Benefits

• Significantly increases dissolved oxygen levels
• Improves overall water circulation and mixing
• Eliminates thermal stratification in ponds and lakes
• Reduces unpleasant odours caused by stagnant water
• Supports healthier fish and aquatic life
• Enhances biological breakdown of organic waste
• Helps control algae growth through improved oxygen balance

When to Use

• In ponds suffering from low oxygen levels
• During warm weather to prevent oxygen depletion
• In systems with visible stratification or stagnant zones
• For improving fish survival and stocking density conditions
• As continuous, seasonal, or emergency aeration support

How It Works

• Draws water from lower depths and propels it into the air
