Factors to Consider when buying a Pond Aerator?
There are a number of factors you should consider when buying a pond aerator, let’s take a look at a few of the most important ones now.
Size of the Pond
It stands to reason that the size of your pond is the most important variable. You will need to know approximately how many gallons of water are in your pond so that you can purchase a device with sufficient power to aerate the pond.
Most aerators will clearly state the gallon capacity within their specifications. It is generally recommended that you buy a unit that has more power than you need.
For example, if your pond is approximately 1,500 gallons in size a 2,000-gallon aerator should be the size you aim for.
Bear in mind that some of the largest aerators measure their capacity in acres. If you have a very large garden pond, you may already know the size in terms of acreage.
To help work out the size of your pond, the guys over at Pond.com have created a very handy calculator.
The shape of the Pond
Pond shape is also a factor when deciding on which aerator to buy. A small, circular pond will work with a low powered model as this shape can be aerated by any type of diffusion system.
Essentially, it is easy for oxygen to be evenly distributed around a circular shaped pond.
However, if your pond is larger, with irregular shapes and channels the oxygen cannot travel evenly throughout the water. A different type of aerator will need to be used under these circumstances.
In fact, for specialized ponds that have been created to landscape a garden, speaking to an aeration service provider is recommended. They will be able to advise on an appropriate aerator for the job.
Depth of the Pond
Finally, there is the issue of pond depth. Some aerator models have a maximum depth point. Beyond this, they will not be able to circulate oxygen efficiently. In some cases, it will mean aerated water is not even reaching the bottom sections of your pond.
Again, the model should state its depth capacity within the specifications. You should measure the depth of your pond (to know the average depth, plus what the deepest point is), and buy the correct aerator accordingly.
Different types of Pond Aerators
Submersible vs Floating Fountain Pond Aerators
The main types of pond aerators are submersible or floating fountains.
As the name suggests, a submerged aeration system is placed beneath the waterline and slowly releases oxygen directly into the water. This type works well for irregularly shaped ponds as they can be positioned so that hard to reach sections of the pond receive oxygen.
Floating fountain aerators are a popular choice for circular and/or uniformly shaped ponds. This is because they work best when positioned in the center of a pond. The units provide aeration via the falling water of a fountain. In other words, they double up as an attractive water feature.
Linear compressor vs rocking piston
The compressor is the part of the unit that does the heavy lifting in the aeration process. It is what creates the force that in turn oxygenates the water.
The two main types of compressors you’ll find in today’s aerators are the linear compressor and the rocking piston compressor.
The linear compressor creates and releases air via an internal diaphragm. This type is best for small ponds as they do not require much power and have a smaller capacity than the rocking piston.
Rocking piston compressors create and release air via a (you’ve guessed it), rocking piston. These units have a high capacity and are therefore better equipped to oxygenate large and deep ponds.
Where should you place your new pond aerator?
A submersible aerator is best placed at the deepest part of your pond, or near the area that requires the most aeration, (which is generally the deepest part of the pond 🙂 ).
This is because the silt, muck, and organic material will gather near the bottom, are to aerate this will make for a healthier pond.
With a fountain aerator (for use in a small pond), the center of the pond is the best position, so that the water can be aerated evenly.
Again, if you have a large pond where expert advice would be helpful, you should contact an aeration service technician to guide you.
How to Install a Pond Aerator?
Installing a pond aerator is a relatively simple procedure, however, it does differ depending on the type of device you have.
Submersible aerator installation
With your aerator unpacked, the first step (after choosing the installation location) is to fill the diffuser. This has to be weighed down so that it can be submerged under the water. Gravel is the normal choice.
The pump part of the aerator should be positioned on dry land. You will also need an energy source for this. (Some are solar-powered, others will need electrical mains hook-up).
Link the diffuser up to the pump via the provided tubing, and then drop it into the deepest part of the pond. After this, you should be ready to go. Switch the pump on and stand back as your pond is aerated.
Fountain style aerator
A fountain style aeration unit is installed in much the same way, in terms of needing the pump to be on dry land and connected to power (or have the solar panel positioned to collect sunlight).
The difference of course is that in absence of a submersible diffuser, you have a device that creates the water fountain. If you do not have the means to set this up in the center of the pond, it can be placed at the edge, with the impact of the fountain hitting the center area of the pond.
The fact that these are designed for small ponds, makes this possible.
When to Run Pond Aerator?
So should you keep your aerator working all year long?
The answer is yes if you can. In cold climates, it can be prudent to remove the aerator in winter if your pond regularly freezes completely.
In summer months it is definitely advised that you keep the aerator running constantly. During hot weather, warm water has less dissolved oxygen in it. There’s also a higher level of decomposition taking place.
To ensure your fish have enough of that beautiful oxygen, your aerator should be churning away throughout.
