What does an aerator do for a pond?
Running an aerator pumps fresh O2 in the water while maintaining a hole in the ice for gas exchange. Ideally, an aeration system should be matched to your pond's size and shape, and run all season.

What are the benefits of using a fountain aerator?
Fountain aerators also aid in mosquito control and fountains are the aeration device of choice specified by many State and County construction codes for permitting in new retention pond applications.
What are the benefits of Airmax aeration?
Aeration with the Airmax Aeration System, which involves diffusing oxygen into the water below the surface, benefits the quality of your pond or lake in myriad ways, including these top five reasons: Reduces Pond Muck: Aeration cuts the nutrient load, like pond muck and other decomposing debris, in your pond. How?
Do you need to aerate a pond?
If you have fish in your pond, aeration is not just important, it is absolutely vital for their survival. Without aeration, fish would not have sufficient oxygen to breathe and beneficial bacteria would not be able to keep up with bio-filtration, so water quality would rapidly deteriorate.
How much aeration does my pond need?
CALCULATE NECESSARY AERATION Normal aeration requires the displacement of 1 (one) acre foot or 325,900 gallons of water every 24 to 48 hours. This will add a minimum of 3.2 lbs. of oxygen per horsepower per hour. For normal water conditions use a minimum of 1-1/2 HP (one and one half HP) aerator per surface acre.
Do you need an aerator in a pond for winter?
If you have fish that you wish to winter over in your pond it's necessary to use a pond aerator. A pond aerator or small recirculating pump that agitates the water's surface will oxygenate the water.
Do I need an aerator for my pond if I have a waterfall?
Most water gardens rely solely on waterfalls to circulate and aerate the water. While effective, waterfalls generally only circulate and aerate the top portions of the water and may leave many areas of the pond, particularly on the pond's bottom, untouched allowing for the accumulation of organic debris.
Does a pond aerator really work?
Pond aeration is the simple, yet effective, process of increasing oxygen levels in a pond and can not only greatly enhance the aesthetic beauty of a pond, but can also improve the natural systems taking place beneath the water's surface.
Can you over aerate a pond?
What you are looking for is a system that will move the volume of water in your pond to the surface at least once every 24 hours, twice is even better. Don't overdo it; too much air could cause the pond to be turbid.
When should I run my pond aerator?
How often do I need to run my aerator? It is recommended that the aerator is run 24/7 for optimal aeration benefits. If you need to restrict running time, be to run the aerator run at night during the dark phase of photosynthesis, this is when aquatic vegetation reproduces the most.
Where should a pond aerator be placed?
The most important reason to place your diffuser in the deepest part of your pond is to get the water circulating. Water in the deepest part of the pond should rise to the surface, come in contact with both sunlight and wind, and get an injection of much needed oxygen.
When should I turn off my pond aerator?
Here's the shutdown process we recommend: Unplug and shut your aeration system down completely. It's critical to do this before the ice starts to build on your pond's or lake's surface for the safety of those who will skate on the pond.
How do you aerate a pond naturally?

If you have aMoreYou can create a water flowing upon to create a very steady and reliable aeration. If you have a smaller pond you can add things like fountains.
Does an aerator keep a pond clear?
The benefits provided by bottom diffused aeration will keep your pond clean, clear and balanced all season long. Aeration is key in the summer months to keep dissolved oxygen available for your fish with warm temperatures.
Will a waterfall oxygenate a pond?
So, a waterfall will aerate a pond. But the aeration is limited mainly to the nearby surface layers of the water. Adding a submersible aerator is an effective way to provide aeration throughout your pond. It'll aerate from the bottom up, not just across the water surface.
How many hours a day should a pond aerator run?
We suggest that a fountain or aerator system run twenty-four hours a day, seven days a week. This will give you the most aeration benefit from the unit. If you experience icing where you live, the unit should be pulled out of the water and stored during the months when the body of water is frozen over.
How long should you run an aerator in a pond?
Ideally, an aeration system should run all year long. By running it all year, there is a reduction in the risk of winter fish kills due to turnover. Aeration systems that were shut down in the winter for recreational purposes, will need to be restarted once the ice melts off the pond.

How can I oxygenate my pond quickly?
A very simple way to add oxygen to the pond is to add an air pump. Sitting at the side of the pond, it will pump air through a small hose to an air stone and bubbles will enter the water. When the bubbles break the water's surface oxygen will then be added.
How Do Pond Aerators Work?
Pond aerators oxygenate the water by using a propeller to create movement in the water and create a boiler effect from the thrust that gets oxygen into the water. This is similar to air pumps that take oxygen from the air outside of the water and then pump this air into the pond.
What Is Aeration and How Does It Help Ponds?
Aeration is the process of adding air into something. When it comes to ponds, aeration adds and circulates oxygen throughout the water.
How many diffusers can I use with 1/4 HP?
You will see some overlap here in the number of diffusers powered by a particular pump. The 1/4 HP compressor can effectively work with up to 2 diffusers but not more. The 1/2 HP is very commonly used in 3 diffuser systems, but can be very good at powering two diffusers as well. We might use this combination in deeper ponds of 25′ or more. It should not be used with one diffuser (which may create excess back pressure on the pump), nor would I routinely use it with four diffusers in a typical aeration system, although it could be used with four diffusers in some shallow water ponds that are less than 10′.
How much air does a pond aerator need?
As you add diffusers to a system, usually a larger pump will be required to maintain adequate air output out of each one. We aim for no less than 1.5 cfm’s of air out of a diffuser.
How deep should a pond aerator be?
Large pond aerators, at least as far as the current market and offerings are concerned, can be broken down into a few categories. First of all, in this article, it should be noted that we are focusing on the sub-surface, diffused aeration systems. In this category, there are shallow pond systems, most of which are designed to work in ponds of 6′ or less, and standard or more deep water systems that are rated down to 50′ of depth. I do try to maintain a bit of a buffer off that max depth however and prefer to max them out at 35 to 40 feet.
How deep should a diffuser be to aerate a pond?
Here’s an example. If I were to put a diffuser at 6′ of depth I may be able to effectively aerate about a 1/4 of pond area…and that’s probably being generous. The same diffuser, placed at 12 to 15 feet, will aerate up to an acre and provide excellent mixing and oxygenation.
How deep should a pond be for a SW40?
If your pond is shallow, the best system I can recommend is the Airmax SW40 which will work in ponds up to 1/2 acre. The max depth is rated at 6′ and it includes 4 diffusers and uses a linear compressor which is both efficient and quiet.
What kind of pump should I use for a pond?
If the pond is 8′ or deeper, I would consider something like the Kasco RA1 which uses a 1/4 HP pump, and a single diffuser. If the pond is really oblong and stretched out, I may lean more to the Robust-Aire RA2, which uses the same pump but includes 2 diffusers. This helps spread the air out a bit better and mix the entire pond more effectively.

How deep should a bottom diffuser be in a pond?
By having a bottom diffuser placed no deeper than 1/3 the total pond depth (and close enough to shore that anything that goes into the water can walk back out without climbing up on the ice) to keep an area open that is approximately 10% of the total pond surface, you will prevent most if not all winterkill problems.
What is a volcano agitator?
Volcano Agitator. Paddle Wheel-type agitator. Fountain. PTO-driven agitator. Fountains are used both for display and to aerate shallow bodies of water, volcanos are more for adding oxygen to the water and less for aesthetics and paddlewheels/PTO driven agitators are more for aquaculture production ponds.
What are the two types of aeration?
There are basically two types of aeration: surface aeration and bottom diffusion aeration . Surface aeration can be broken down into further into the three more categories of fountains and surface agitators, and circulators. Bottom diffusion systems can be broken down into three different categories as well: grid based or electrically operated, solar operated, and windmill or wind driven systems.
How often do windmill compressors need to be rebuilt?
The compressors (in my experience) need to be rebuilt every 2-4 years, and to do that you either need to tip the windmill tower over to get the compressor to the ground, or climb the tower and work in the air. If the system is floating on the pond, then you just need to bring it up onto the shore to work on it.
How much air do you need to move a water diffuser?
A rule of thumb to remember is that for every foot of water depth that the diffuser is placed at, you need 0.5 psi to get air to that diffuser.
How long does it take to rebuild a compressor?
The compressors do have to be rebuilt from time to time, but depending on the type of compressor the rebuild interval could be 2-3 years or over 10 years. The key is to furnish them with clean air, keep them well ventilated and use the appropriately sized wire to bring power to the compressor.
Why do we use bottom diffusion aeration?
They are used to bring the low oxygen bearing water to the surface so it can absorb oxygen from the atmosphere . In terms of energy efficiency, where applicable, bottom diffusion aeration systems will give you more bang for the buck, i.e. move more water for less dollars per hour operating expense.
How Long Should A Pond Aerator Run?
In general, a pond aerator should only be run intermittently for about a day at a time. This will give the aeration system plenty of time to run through all of the water in the pond, and this will lead to a healthy environment for your fish.
Can You Aerate Water Too Often?
One of the things that you need to be concerned about is putting too much oxygen into the water. This can cause it to become turbid. That is why it is recommended that, as a general rule, the aeration device should only run for about 24 hours.
What Is A Proper Amount Of Oxygen?
The oxygen level of any pond should never drop below 3PPM. This is the minimal amount of oxygen that is required. Anything below that can lead to fatalities for most fish that you would have in the pond. You will be able to tell if it is missing a proper amount by looking at the interactions of the fish.
Ways To Improve Oxygen Levels In A Pond
There are several techniques that you can use to increase oxygen levels in a pond. First of all, you should provide some type of covering. This will prevent the air from leaking out into the surrounding atmosphere, and it will also minimize often you will have to aerate the water.
