The Best Fountains For Aeration? - Comparing The Scott Aerator DA-20 and The Kasco VFX Series
When evaluating the best aerating pond fountains on the market, the Scott Aerator DA-20 and the Kasco VFX Series consistently stand out. Both are proven, high-performance surface aerators designed to increase oxygen levels, improve water clarity, and enhance the visual appeal of ponds and lakes.
However, each model takes a very different engineering approach, and those differences matter depending on your pond size, power setup, and long-term maintenance needs.
Below is a detailed breakdown of their respective advantages and limitations.
Scott Aerator DA-20: Strength, Durability, and Winter-Safe Engineering
The Scott Aerator DA-20 is widely regarded as one of the most rugged, high-output aerating fountains available today. Its focus is raw performance, long-term reliability, and all-season operation, making it a top choice for property owners who want maximum aeration without the hassle of seasonal removal.
Advantages of the DA-20
1. Winter-Safe, Year-Round Operation
The DA-20 can run through winter to keep ice from forming around the motor, or it can be shut off and safely left in the water until spring. No seasonal removal is required—an uncommon benefit in the fountain industry.
2. Oil-Free, Environmentally Friendly Motor
The motor is water-cooled and completely oil-free, eliminating environmental risk and reducing long-term maintenance.
3. High Flow Rates for Superior Aeration
With flow rates up to 48,000 GPH, the DA-20 delivers aggressive surface agitation ideal for ponds struggling with low oxygen, algae, or stagnation.
4. Industry-Leading 5-Year Unconditional Warranty
Every unit comes with a full five-year warranty, signaling strong confidence in build quality.
5. Wide Range of Horsepower Options
Multiple sizes allow owners to match the fountain to virtually any pond footprint or depth.
6. Optional White or Color-Changing LED Lighting
Lighting kits are available for enhanced nighttime aesthetics.
Limitations of the DA-20
1. Performs Best on 230V Power
While 115V setups work, the stronger motor requires adequate power. The breaker panel must be within approximately 70–100 ft for 115V installations.
2. Slightly Higher Operating Cost
The powerful motor draws more electricity, costing $0.06 to $0.32 per hour depending on horsepower.
3. Requires Moderate Water Depth
Minimum depth requirements range from 32" to 42", depending on the model.
Kasco VFX Series: Energy Efficiency, Shallow-Water Performance, and Turnkey Convenience
The Kasco VFX Series is known for exceptional energy efficiency, reliable operation, and a low-profile design that thrives in shallow ponds. Kasco engineering focuses on power savings, easy installation, and flexibility when 120V power is the only option available.
Advantages of the VFX Series
1. Extremely Energy-Efficient Motors
Amp draws range from 3.7A to 20A, making the VFX line one of the lowest-cost fountains to run in its class.
2. Exceptional Shallow-Water Compatibility
Smaller units operate in as little as 15" of water, while even the 5 HP model requires only 26", truly industry-leading depth requirements.
3. Lighting Options Available
Both color-changing and bright white LEDs can be added.
4. Includes Control Panel and Anchoring Hardware
Each unit ships with a dedicated control panel that manages fountain and light scheduling. This simplifies installation and removes the risk of using mismatched third-party controllers.
5. Ideal for 120V Power Situations
When only 120V power is accessible, Kasco’s low-amp design minimizes voltage drop and maintains reliable performance.
Limitations of the VFX Series
1. Must Be Removed for Winter
Kasco uses oil-cooled motors, which are not winter-safe. The unit must be pulled from the pond before freezing temperatures arrive.
2. Less Aeration Output on Lower Horsepower Models
Energy efficiency comes at the cost of reduced plume size and aeration intensity on smaller horsepowers.
3. Shorter Warranty Period
Warranty coverage ranges from 2–3 years, depending on the unit—shorter than many competing manufacturers.
Which Aerating Fountain Is Best?
If you need maximum aeration, rugged durability, and true year-round operation, the Scott Aerator DA-20 is the stronger performer.
If you need energy efficiency, shallow-water compatibility, or a simple all-in-one package with a control panel included, the Kasco VFX Series is the better fit.
Both are excellent, but the right choice depends on your pond’s depth, power availability, and aeration goals.
