Surface Aerators

What Makes Our Surface Aerators a Good Choice

Strong Performance

Our aerators move a lot of water and add plenty of oxygen to your pond, which helps cut down on algae and keeps the water from going stale. For bigger spaces like lakes or golf course ponds, the Kasco 5 Acre Pond Aerator is a great fit and has a 5 HP motor. Power House Surface Aerators are also popular for their high oxygen transfer rates and can work in shallow water, as little as 14 inches deep. If you're not looking for surface options, explore all our pond aerators for other powerful solutions.

Made to Last

All our surface aerators are built with strong materials like stainless steel and heavy-duty plastic.

• The Scott Aerator Amherst Pond Fountain is made in the USA, needs no maintenance, and even works in saltwater. It comes with a 5-year motor warranty and a 1-year warranty on everything else.
• The Air-O-Lator Aquarian Pro also runs year-round with very little upkeep and includes a high-quality Franklin Electric motor. It's backed by a 2-year warranty.

Fits All Pond Sizes

It doesn’t matter if you’ve got a small backyard pond or a large lake; we’ve got aerator options that fit. The Aquarian Pro comes in sizes from ½ HP to 1.5 HP. Power House models range from ¼ HP to 1 HP and offer different cord lengths and voltage setups (115V or 230V).

Simple Setup

Most surface aerator models are plug-and-play. You won’t need special tools to install them. Once in place, they’re good to go, and many can stay in the pond through the winter.

Saves Energy

The Power House aerators are known for low energy use thanks to their high-thrust, low-amp motors. The Air-O-Lator Aquarian Pro is also designed for strong performance, even with less power.

Add-On Options

You can upgrade your aerator with extras like lighting or winter protection.

• The Kasco LED Light Kit adds colored lights (Amber, Blue, Green, Red) and comes in 3- or 6-fixture sets.
• The Scott Aerator has Night Glo LED sets in warm white or 14 color options, plus a digital timer.
• The Aquarian Pro can be paired with a Sling Rope De-Icing Kit to help keep an open area in winter so fish stay safe.

Maintenance and Long-Term Use

Most of our surface aerator models require little to no regular maintenance. The motors are sealed and protected against moisture and debris, which lowers the chances of clogs or failures.

• Debris Protection Options: For added protection, models like the Kasco and Air-O-Lator have optional screen guards that block large debris from entering the motor housing.
• Oil-Free Operation on Scott Aerators: The Scott Aerator fountains have sealed bearing systems. This means there’s no oil to check or replace, making them even easier to care for over time.
• Simple Part Replacement: If maintenance is needed, most replacement parts are readily available and easy to install with basic tools. There’s no need for professional servicing in most cases.
• Routine Check Suggestions: Regularly removing leaves or sediment buildup around the motor will help extend the life of your aerator even more. A quick cleanup now and then can prevent future problems.

For cold weather areas, many of these models can stay in the water through winter. That said, some customers choose to remove and store them if their pond completely freezes over.

Frequently Asked Questions

What Are Surface Aerators?

Surface aerators are devices that sit on or near the surface of your pond and stir up the water to add oxygen. Some float, some sit at the edge, but they all help keep the water moving and well-aerated.

What Do Surface Aerators Help With?

Surface aerators improve water quality by raising oxygen levels, which helps reduce algae, lowers the risk of fish dying from low oxygen, and cuts down on still or smelly spots. They also help spread nutrients more evenly through the water.

How Do Surface Aerators Work?

Surface aerators splash and move the surface of the water to mix in more oxygen from the air. That surface movement helps freshen up the whole pond. Depending on the model, they might run on electric power, solar, or wind.

Are Surface Aerators Okay for Small or Big Ponds?

Yes, you can find a surface aerator that fits pretty much any pond size. If you’ve got a small decorative pond or something much larger, there’s a surface aerator that’ll work for it.

How Do I Pick the Right Surface Aerator?

Think about your pond’s size and depth, what your budget looks like, and if you’ve got any water problems like algae or murkiness. Contact Your Pond Pros at support@yourpondpros.com for expert advice and high-quality pond equipment.

Are Surface Aerators Hard to Set Up or Take Care of?

Not really. Most surface aerators are easy to install and don’t need much upkeep. Just give them a quick check now and then, and clean off any debris. They’re usually simpler to manage than other types of pond equipment.
