Sizing help
Not sure how much horsepower your pond needs?
Aeration is sized on surface acreage and depth, not on how much spray you want to see. Send us your acreage, average depth and the voltage available at the site, and our techs will spec the unit before you spend a dollar.

Surface Aeration Moves Volume. It Does Not Reach the Bottom.
A surface aerator pulls water from just below the surface and throws it into the air, driving oxygen exchange across a wide area with no spray display to pay for. Per horsepower it moves considerably more water than a decorative fountain, which is why it is the default choice on lagoons, retention basins and golf course water where the unit is there to work rather than to be looked at.
What it will not do is turn over a deep water column. Surface units work the top few feet. On a pond deeper than roughly eight feet, water below that can still stratify and go anoxic through a hot Ontario August no matter how much surface agitation you add. That is the point at which bottom-diffused aeration earns its keep, and on larger water the two are often run together.
Sizing starts with surface acreage and depth. As a working rule from our own installs, plan on roughly 1 to 1.5 HP per surface acre, then confirm the voltage and phase available at the site before you choose a model - it narrows the list faster than anything else. Send us those numbers and we will do it for you.

I have had the pleasure of working with Ryan from Fountain Depot for the past year +. He designed and rebuilt our fountain from the ground up. They are a very knowledgeable team of guys. Our condo community could not be happier with the job they did for us. Highly recommend them for all your fountain needs.

I highly recommend the Fountain Depot. Ryan and his team are incredibly knowledgeable and timely. We sought a floating fountain and underwater lights for our client, and Ryan delivered precisely what our client was desiring. The Fountain Place continues to maintain the fountain, and we have had zero issues.

Buying guide
Questions our techs answer every week
Horsepower, voltage and phase all have to line up before an aerator ships. Here is what we get asked most.
Start with surface acreage and average depth. As a working rule from our own installs, plan on roughly 1 to 1.5 HP per surface acre for meaningful oxygen transfer.
That puts the 1/2 HP 2400AF on small residential ponds, the 3/4 HP and 1 HP 3400 and 4400 units on a quarter to a full acre, and the 2 HP 8400AF and the 3 HP and 5 HP models on larger commercial water. Send us your acreage and depth and we will confirm before you order.
Does a surface aerator come with a control panel?
It depends on the model. The three-phase 3.3AF and 5.3AF ship with a Kasco CA-3235 control panel included. Every single-phase model - 2400AF, 3400AF, 3400HAF, 4400AF, 4400HAF, 8400AF, 3.1AF and 5.1AF - ships without a panel.
If you are buying single-phase, budget for a control panel separately. It gives you proper disconnect and overload protection, plus timer and thermostat options.
What is the difference between the 3400AF and the 3400HAF?
Voltage. Both are 3/4 HP single-phase, but the 3400AF runs on 120V and the 3400HAF runs on 240V. The same applies to the 4400AF and 4400HAF at 1 HP.
The H prefix is the tell. Check the supply at your power source before ordering - it is not a plug swap, it is a different unit.
What warranty comes with a Kasco surface aerator?
The 2400, 3400 and 4400 series carry a 2-year Kasco warranty. The 8400AF and every 3 HP and 5 HP model carry 3 years.
Because we are an authorized Kasco dealer and run our own repair centre in Markham, warranty work is handled here rather than shipped across the border.
Surface aerator or diffused aeration - which does my pond need?
Surface aeration works the top few feet of the water column and covers a wide area per horsepower. Diffused aeration releases air at the bottom and lifts the entire column, which is what deep or stratified water actually needs.
Under about eight feet, a surface unit is usually enough. Deeper than that, look at RobustAire diffused aeration, or run both on larger water.
Can I run a surface aerator through a Canadian winter?
A surface aerator is not a de-icer, but paired with a thermostat control panel it can be used to keep water moving as temperatures drop. Kasco also offers a conversion kit for compatible motor units.
If ice prevention around a dock or boat lift is the actual goal, a purpose-built de-icer is the right tool. Tell us what you are protecting and we will point you at the correct one.
