Surface Aerators

What Are Surface Aerators?

Surface aerators are a kind of pond aerator designed to the top layer of water, promoting rapid oxygen transfer from air to the liquid. By pushing high volumes of water into the air, they expose more water to atmospheric oxygen and mix it back into the pond. 

This process of surface aeration breaks up thermal stratification, reduces algae growth, and maintains clear, healthy conditions for fish and aquatic plants. 

Unlike bottom diffusers, surface aerators focus power where sunlight and heat can create low‑oxygen zones.

Benefits of Surface Aerators

Boosting oxygen and movement at the water’s surface sets the stage for a thriving pond. These key benefits demonstrate how surface aerators keep fish active and prevent algae growth.

• Improved Oxygen Transfer- Surface aerators deliver up to 3.0 lbs of O₂ per horsepower per hour, ensuring fish and beneficial bacteria thrive.

• Algae and Odor Control - Continuous mixing prevents nutrient buildup and discourages algae blooms and foul smells.

• Prevent Stratification - By disrupting thermal layers, aerators keep all water layers mixed, which improves overall water quality.

• Visual Appeal - Many models create attractive spray patterns, turning your aeration device into a water feature.

• Cost‑Effective Operation - Lightweight units use half the electricity of comparable fountains, and solar‑powered options eliminate power costs.

Types of Surface Aerators

Choosing the right aerator sets the stage for clear, healthy water. We categorize our Surface Aerators to help you quickly find the perfect match.

Residential Pond Aerators

These aerators and aerator fountains are self-contained, easy-to-install units are designed for backyards and small ponds up to 1 acre in size.

Models like the Scott Aerator DA‑20 Display Pond Aerator Fountain deliver moderate mixing and charming trumpet sprays. Lightweight units under 1 HP can be set up by a single person using supplied floats and mooring lines anchoring kits.

Stainless steel components and flood-oil lubricated motors offer corrosion resistance in humid or saltwater environments.

Commercial & Industrial Aerators

For larger and more demanding applications, such as lakes, wastewater treatment facilities, and aquaculture operations, our commercial and industrial aerators are built to handle the task.

We offer heavy‑duty Kasco Surface Aerators from 2 HP to 5 HP. These units use robust propellers to mix high volumes of basin water and are ETL-listed to UL/CSA standards. 

Industrial models feature stainless steel domed tops paired with double mechanical seals, designed to dissipate heat and prevent leaks or vibration in harsh environments. 

A flood oil lubrication further extends motor life during continuous operation.

Solar-Powered Aerators

Our solar-powered aerators are an excellent choice for those seeking an environmentally friendly and cost-effective solution, particularly in remote locations without easy access to electricity. 

These self-contained units pump up to 500 GPM without a power cord, providing reliable aeration without the need for electrical connections or ongoing energy costs. 

The systems typically include float assemblies, solar panels, and programmable solar controllers housed in weatherproof enclosures.

They are ideal for off-grid ponds, wildlife habitats, and anyone seeking to minimize their environmental impact.

Surface Aerator Accessories

Keeping your aerator humming means more than just picking the right fountain. The right extras tune performance, cut maintenance, and add flair after dark. 

Below, we break down each add‑on in plain terms and show how it plugs into your pond setup.

Automated Control Panels

These all‑in‑one control boxes streamline power and run cycles for surface aerators. With these controls, you can program on/off times once and forget them. Additionally, the built-in GFCI protection safeguards both your pump and your dockside outlets. 

Having a dedicated control panel means your aerator won’t burn out from phase issues or get left running when you’re away.

Lighting Kits

Turn your nighttime pond into a light show. 

WaterGlow kits snap onto most surface aerators and spray nozzles, casting colors across the water curtain. They run off the same power cord and mount in minutes. 

Beyond aesthetics, lights improve safety by revealing spray patterns along the shore after dark.

Mooring Line Anchoring Kits

Keep that aerator exactly where you placed it. Mooring kits include UV‑resistant ropes and shore anchors sized for Kasco floats. 

No more drifting off‑center as wind and waves push—just tie off once and enjoy uniform oxygenation across your pond’s surface.

Flex‑Sleeve Cord Protectors

When your aerator’s motor cord snakes across rocks or hidden edges, it needs armor. 

Flex-sleeve protectors slide over flood-oil-lubricated motor leads up to 500 feet long. They fend off abrasion and pinch points so cables last years longer without kinks or cuts.

Debris Guard Screens

Slip a debris guard screen beneath the Scott DA‑20 pump to block clogs before they start. 

These stainless-steel mesh filters allow water to flow freely while keeping unwanted debris out of your impeller. 

Winterization Kits

To help protect your aerator during colder months and prevent ice formation.

Note: The availability and compatibility of the accessories above vary by model, so please verify which add-ons are compatible with your unit.
