Pond Aerator For Sale: Solar, Pumps, Fish Tanks, Systems

Pond aerators are important devices to put in a pond in order to significantly improve the quality of the water, and on this page we have listed for sale all the various devices you can buy through our website, as well as see just some of the many benefits you should be aware of, how powerful of a machine you will need as well as a bunch of other useful stuff.

What does an aerator do for a pond?

Aerators have a lot of different benefits that ensure the proper conditions for the various wildlife in the pond, including improving the water quality and thereby becoming a better fish habitat, too.

In addition it reduces the phosphorus concentrations, which in turn helps limit the algae growth; a feature most people with a pond are happy about. It is very difficult to otherwise lower these concentrations once phosphorus has made it into the ecosystem, although with the use of oxidative reactions, you can have the phosphorus naturally bind with iron, at which point it precipitates and becomes unavailable as an energy source for the algae that would otherwise be feeding on it. The process does, however, require sufficient levels of dissolved oxygen, why the use of an aerator is heavily encouraged.

There are different types and strengths of aerators out in the market for you to consider, and we’re hoping to provide you with the necessary information on this page, allowing you to make an informed decision.

Do ponds need aerators?

While you can find a lot of different information regarding the need for pumping oxygen into a water feature, the obvious question in the back of a lot of people’s heads remain whether or not it is really necessary to get an aerator.

When most people choose to get a pond, they don’t realize that they are in fact not building something that is natural the same way that nature would have built it. The linen that they use does not accurately reflect what nature would have done, and as a consequence, there are certain things that you just need to do to keep the pond up to the level that most people want to keep it.

Let us ask you this question a different way. Did you have a pond installed with the intention of only doing the absolute bare minimum amount of work to it, knowing that algae would overgrow it, or did you have it installed to have a place or tranquil, a little piece of heaven on your property?

Having that little piece of heaven just bring a level of serenity to your property that you won’t be getting from simply installing the usual landscaping on it. If you want to keep a healthy pond, there are certain things that you will need to do, and one of them simply includes aerating.

Atmospheric diffusion is a very real thing that you won’t be getting in a man-made pond, while mother nature is able to provide the level of oxygen required under natural circumstances. A pond aeration system is just one of those things that are needed to ensure that an optimal amount of oxygen is provided.

Without the right oxygen levels, resulting from stale water, there will be consequences that you don’t want to have to deal with, that include severe algae blooms, unpleasant odors and a higher difficulty keeping fish alive, too.

Aeration can additionally be introduced in a couple of different ways, including with the inclusion of a water fountain.

What is the best way to aerate a pond?

If you’ve been looking around, you have probably noticed that your various choices are pretty broad when it comes to getting a pond air pump, whether you choose to go solar or not.

Of course, if you live in an area that doesn’t get a lot of sun, you can naturally rule that option out as it’s really the best option to keep the pump going at all times in order to avoid stale water for extended periods of time. When you have a pond, you will also need a device that is significantly bigger than what you would have needed for a simple fish tank.

How much aeration does a pond need?

How much is really the right amount, is a question you probably find yourself asking, not just when you’re looking to figure out what will create the ideal conditions for your outdoor adventures but also for your various other projects and endeavors you may be running into in life, and this project of yours is no different.

To find out just how big of a pump you will need, you will need to find out how big the area is in acres, which is done easily by multiplying the length by the width, both in feet, which will give you the square footage of the area, which you will then have to turn into acres by dividing by 43,560.

When you have calculated the acres of surface, that is when you’ll know just how much aeration you need as you’ll need at least 1.5 HP aerator per surface acre as 3.2 lbs of oxygen is produced per hour for every horsepower that the machine has, and you will want 325,900 gallons of water to be displaced at least every 2 days for every acre of surface that your pond has. If you know that the lake is prone to having issues with algae in general, you will additionally need to increase the amount of horse power of an aerator to accommodate.

Our recommendation is that you get one aerator per acre of surface area with at least 1-1.5 HP in order to get the water quality that you’re looking for. If you are already seeing issues with algae, that should be addressed prior to starting the aeration of the pond. This can either be done chemically, or you can physically remove the existing build up, and will help get the issue of algae under control a lot faster, too.

Can you aerate a pond too much?

While it is possible to aerate a pond too much, you will need some serious amount of horse power in order to make it happen. Overly turpid water may be an indication that you are aerating too much, but do remember that you still want to actually move water to the surface every single day. Too much aeration leads to turpid water, whereas too little won’t provide adequate protection against algae, and you may just see more algae growth than you were hoping for.

Do pond aerator pumps need to run continuously?

The whole intention of the action is to ensure you are not having water quality issues that can lead to some of the downsides of not aerating, and there are a lot of instances where you would typically be required to have the pump run continuously to otherwise avoid the issue of algae.

If you continue to see problems with algae, chances are you are not aerating it sufficiently, and that you either need to make sure that the pump you have continues to be used or that you perhaps need something that is able to provide your pond with some more power.

Are pond pumps expensive to run?

Pond pumps are generally not expensive to run, and can be as little as $35 per month. The cost of running the pump will depend on a bunch of different factors, including the size of the surface area you are dealing with, the depth, as well as other factors, like whether or not other circumstances are causing the issue of excessive algae growth. There may also be fluctuations depending on the price that you are paying for gas, and the example that we were providing is obviously not what everyone will end up paying, but may more so be the case for a relatively small option.

How much will you end up paying for the initial piece of equipment?

If you have been looking around, you have probably seen varying prices for some of the pond pumps but a typical pond fountain aerator with a 1hp capacity will usually cost you somewhere between $500 and $600. Other options may be more or less expensive than that.

One of the reasons why you may want to make sure that you are in fact using the adequate amount of aeration for your pond

If you’re out in the wild, it would be pretty crazy if you have never experienced this before, and it might in fact be one of the reasons why you would want to make sure you get the right amount of aeration in your pond, or you just may regret it at a later point.

This is often one of the things that is the most overlooked, but with just a little bit more aeration you may be able to significantly reduce the amount of mosquito larva that arises from the pond. If you’ve gone camping or hiking you might have noticed that there tends to be a lot fewer mosquitoes near a river when compared to a pond, and have you realized the biggest difference between the two by now?

Yes, a river flows at a rapid pace while a pond is fairly stagnant. In mosquito terms, what that means is that they’ll have the peace and quiet that they want in order to lay their eggs, why in turn means that a next generation of mosquitoes are brewing, and will soon be ready to make your life an itchy one. Either getting a pump or an aerator for your pond will make sure that the water gets the movement that it needs to at least lower the amount of mosquitoes that you can expect. Great news, huh? Besides discouraging mosquitoes from laying their eggs there in the first place, it can also help kill the eggs by creating a turbulent surface that kills the breathing process. It’s also a big part of helping create the healthy environment that fish will thrive in, but the limitation of mosquitoes does seem to be one of of the more compelling reasons why people are eager to invest in a quality aerator.

Green pond water?

A pond aerator is a relatively new phenomenon that has only properly started being introduced into the homes of families within the last couple of decades and before that it was really quite common with green pond water. The issue is that this green pond water is basically the result of excessive algae growth, and the best way for you to be dealing with that in the first place is to encourage aeration. When you’re properly aerating the water, you are making the conditions less ideal for algae to grow there, basically meaning that you are starving the algae, which is done by increasing the amount of contact between water and oxygen. As with other organisms, the growth of anything is really a result of the good conditions for that thing to grow, and while it used to be believed that you simply had to filter the water from fish waste and fallen leaves, the truth of the matter is that an aerator does a much more efficient job than any of those other methods that you may think of.

If your pond has a bunch of green water in it, it may be an indication that there isn’t enough oxygen being pumped into it, but it could also be an indication that there are a bunch of other things that aren’t perfectly aligned. We don’t want to necessarily encourage you to buy a pond aerator just to find out that it is in fact something else that is causing the problem for you. It might be something else, like the fact that you aren’t introducing good bacteria into the pond like koi clay, barley straw etc.

If you have come across other websites out there, looking for solution for that green water you’ve been dealing with, you also know that it isn’t just about fixing the bacterial composition in your pond, but that you simply can’t fix things if you aren’t properly aerating.

While making sure that the bacterial composition is the way that it is supposed to be, you should be making sure that you aren’t throwing too much fish feeding into the pond as it does encourage algae growth. You may just want to actually reconsider whether or not the amount you have been feeding is in fact the right amount or not. Find out how much feeding your fish really need and you will be having a cleaner pond as a consequence, too.

Pond aerators aren’t the only things that we can help you find, we can also help you with things such as plasma cutters, for instance.

How to aerate a pond without electricity

There are times when you may not have access to electricity by the pond that you have, but you still do not want to be experiencing the symptoms that stem from the fact that you aren’t giving your pond the love and attention that it deserves. Simply leaving the pond to do its thing, because you aren’t able to get something like a generator to stand and provide constant power to actually make sure that enough oxygen gets into the water isn’t an option, but luckily there are things that you can do to solve this.

Types of water aerators

Luckily there are different types of water aerators, and there are some, like the solar-powered ones that can be used without electricity, as they are generating the amount of power that they need themselves. There are, however, some of the types that are more common than others, with some of them offering significant advantages such as energy-efficiency.

With the installation of the right type of equipment, you can avoid that your koi or other types of fish end up getting killed, and you avoid too much algae building up as well. By having moving water, even one that operates without electricity, you can also keep a pond from freezing, by installing a device that can rely on a different type of power, like wind.

In the section below, we will go through some of the various devices that you could consider, and why you might consider those individual options. What are those pros and cons? We will go through all of that and ensure that you end up making the choice that is right for your pond!

Sub-surface pond air diffusers

These are pieces of equipment that are lying on the bottom of the pond, where oxygen is diffused. They are commonly referred to as subsurface aerators or diffused aeration systems, allowing oxygen to reach the very bottom of the pond. With the way that they are working, you won’t get any objects visually blocking the view, which you will get with some of the other systems that we will be going through. You will also be getting the advantage that there is no above-surface air being sprayed around, and you’ll be able to sit in a boat in the middle of the pond without having the amount of noise that some of the other systems will be producing. They’re powered by an air compressor standing on the shore, pushing oxygen through the hose, delivering it to somewhere at the bottom of the pond. Avoid a large spray patter and any above-surface disturbances on the water.

For these reasons, it’s no surprise that this type of machinery is popular for golf courses and places where the water aeration needs to be regulated carefully without the need to get to the aeration system in the middle of the lake. The air bubbler is another type of sub-surface option to consider!

Floating fountain aerators

Floating fountain aerators are another solution that you may consider looking into, which does provide a couple of benefits if you are into the look that a typical fountain will provide you with. However, fountains do not pump water up into the air with the use of magic, but do depend on being hooked up to electricity. Being able to take water from further down the pond and pumping it up, at which point it is sprayed up, the fountain provides great options for putting oxygen at the lower parts of the body of water. There are different options for different sizes and requirements for the body of water that is being treated, but there is no doubt that there is something calming stemming from looking at a floating fountain aerator, especially knowing that it is providing a crucial service for your water.

Whether you have a large or a small pond, you can find a floating fountain that provides the level of oxygenation that your pond needs, and they can additionally be installed as an addition to another aeration system if the model you have chosen does not provide the amount of power that you need. Golf courses, lakes, resorts, country clubs and other places where you want to add that additional tranquility that comes with a nice fountain, may just be some of the places where you will be finding them.

Windmill aeration systems

It is vital that the body of water you have gets the necessary amount of oxygen added to it in order to avoid foul odors, but you may not always have the luxury of having easy access to electricity by the water, in which case you might want a system that doesn’t rely on either an air compressor or another electrical device. The windmill system has the benefit of providing a very eoc-friendly option, while arguably not being the prettiest thing that you can put in the body of water. If there is just a bit of wind by your pond or lake, there is a good chance that this is a viable option to consider, needing as little as 3-5 mph winds, and you can easily find systems capable of aerating bodies of water of 2-3 acres in size. If your needs are bigger than that, you may add multiple of these in order to get the job done.Using multiple of these will help get the oxygen properly dispersed across a bigger area of the water, and providing better protection against algae as a consequence.

The windmill aeration system is a popular choice when it comes to keeping a pond from freezing without the need for electricity, given their eco-friendly nature. Have a pond of 1/8 acre, or rather one that is the size of 1 acre? Simply find the one that has enough capacity to avoid having to deal with excess algae in the future!

Solar-powered pond aerators


These are another great eco-friendly option, with some of the options being able to power lakes the size of as much as 5 acres, without providing the visual look of the windmill that some people may not be fond of. However, they do have the big disadvantage that they do rely on the sun’s power, and when you are located in a region of the country that does not get a whole bunch of light, there simply may not be enough power to actually kepe them going. These system are made to run 20 hours per day, but we still encourage you to figure out if you have enough sun light to actually be sure that thi is the right option for you.

Floating devices

There are a range of floating devices that also exist, some prettier than others, that may be operated in a myriad of ways, ranging from solar power to electrical.

Best pond aerators

The same way that there are some options that are better when people are buying a fuel transfer tank, a wide belt sander or an engine driven welder, there are also some options that are better than others when it comes to ensuring that your pond has the necessary amount of oxygen in it.

The best pond aerator comes down to your personal preferences, but we definitely like some of the options, like the diffused AirMax systems that will leave a space visually undisturbed, or a system like the Hiblow.
