Just like how you and I need oxygen, your pond inhabitants need it too. Sometimes there is not enough oxygen present in the pond, so owners have to introduce it manually, that is called aeration. You have plenty of electrical devices that’ll help you with that cause.
Still, there are some situations where you can’t make use of one. Not knowing how to aerate a pond without electricity, many owners get flustered and start making mistakes. Relax! There’s no need to panic.
To aerate a pond without electricity, you can use any solar pump, fountain, or even a windmill. Also, you can achieve that with plants if you strategize correctly.
Does it pique your curiosity? Now, I am going to explain these things in detail down below. So, stay tuned.
Ways to aerate a pond without electricity
“Why should I aerate a pond without electricity?”, is a common question that might pop up in your head. There are quite a few reasons for it actually.
Let’s say you have your pond at a place where you don’t have access to an electrical socket, or you might live in a secluded area where you prefer the beauties of nature over electricity and the internet [I heard that’s a trend nowadays].
Or, you might just want to cut down some electricity bills. You’d be amused to know there are a handful of methods you can adopt to aerate your pond without a pump or other devices that need electricity.
While in some situations, they might not be able to help out in large ponds all by themselves, they are more than ideal for a small pond.
Enough idle chatter, let me show you exactly what you’re looking for:
Fountains
When it comes to aeration, fountains are almost an auto choice. Having one of these helps our goal because there are some solar-powered fountains that you can use.
You should get a solar fountain pump if your pond is exposed to sunlight for a decent amount of time.
It’ll pull the water from the pond and sprinkle it in the air, where the water droplets absorb oxygen and fall back into the pond. A life-saving but straightforward trick for your pond inhabitants.
While you won’t get a powerful output of an electricity-driven aerator, it’ll still give you a decent amount of aeration. Small and medium-sized ponds shouldn’t have any issues using one of these.
If you want, you can also use them for a large pond, but it has to be an extra oxygen rather than being the aerator.
Make sure you choose a pump that has an excellent output and a reliable solar panel. My suggestion would be to go for a pump that has 50-400 GPH. You’ll get better water flow and fountain height from a pump that has a high GPH.
But, like other solar-powered devices, it only works best when there is ample sunlight.
Don’t feel down; there is still a solution. Allow me to let you in on a secret- some solar fountains even come with a battery-operated model.
This way, you won’t be helpless if the sunlight isn’t enough during bad weather, plus you will have the option to run the fountain at night.
A battery pack can give you a 4-6 hour runtime, so you can rely on them on a cloudy day [pun intended].
If you plan to get a solar fountain pump, then I think you should get one of those that come with a battery mode.
Pros
- Next to zero operation cost
- Easy to install
- Adds aesthetic value
- Operates silently
Cons
- Hard to run when the sun isn’t out, unless there is any battery
Aerators
This option is also dependent on solar power to operate, so from a fundamental point of view, it is the same as the one above it. But, what makes it different is the way it delivers oxygen.
It comes with an air pump that can directly supply oxygen in the pond through a tube and a diffuser, so there is virtually no need for water to function. All you have to do is place it above the pond.
The diffuser stones are placed inside the pond so that the air pump has an easier time injecting the oxygen inside the pond.
They are not the best for water movement, but they serve as an excellent independent oxygenator.
You can place it anywhere you like, so it won’t tamper with the aesthetic view you have in mind.
Like the fountain, I’d suggest looking for an aerator with a large solar panel that also has battery packs and tries to get one with big diffuser stones to make your work easier.
There are both standing and floating aerators; from my research I found out that the standing aerators are better at oxygenating a pond.
Pros
- Low operation cost
- Easy to operate
- Directly delivers oxygen
Cons
- Will face problems in low sunlight
- Not a standalone aerator for a large pond
Windmills
Now, it is time for an environment-friendly option to take the stage. They are underrated yet powerful aerators that produce a massive amount of aeration.
Windmills can even aerate large ponds spanning up to 2-3 acres. It aerates the pond via a 1/2″ airline that you will place at the deepest part of the center point in alike.
It comes with a compressor that can produce 4 cfm air of 30 psi. The best ones can do it with minimal airflow.
If you own a large pond you’ll be more likely to install this over other options as it is a little overkill for the small ponds.
The initial cost might be higher than a fountain, but you get long term gains that’ll justify the investment.
You can install it in a remote area and still get good results. As a matter of fact, remote areas might be the best place to use them as there is no obstruction for the flowing wind in remote locations.
There is a little downside to this sadly, installing them alone isn’t easy and it can’t operate without wind.
To bypass this, you need to get a heavy-duty windmill that is capable of providing high output even on low airflow like 3 mph. But these are a bit expensive. This is the initial cost I was talking about.
But it will last for years to come while delivering thorough aeration, so in the end, you’ll be happy you took the leap. Since it can aerate the deepest part of a pond, the beneficial bacteria will thrive, there will be fewer algae growth, and your fish won’t have any oxygen scarcity.
Pros
- Excellent aerator for remote area
- Thorough aeration
- Environment friendly
Cons
- Expensive initial cost
- Minimum three mph of wind flow needed
Plants
Here’s another eco friendly option for you- use plants! I’m not kidding; plants are fantastic at aeration. If you want to go for a 100% natural approach then there is no better alternative to this.
They’re not a match for solar pumps, but you get enough to protect a small pond, plus you get to help the environment a bit.
In my eyes, the best plants for a pond are submerged ones, like hornwort; because directly add the oxygen into the pond water. The ones who have foliage above the pond water will spread the oxygen in the atmosphere.
Not just for providing oxygen, plants also do a big favor by absorbing nutrients like nitrates and phosphates
The beneficial bacteria break down ammonia and nitrites into simpler compounds like nitrates and phosphates. If there were no plants, then these would have been food for algae.
So, by housing plants in your pond, you are making them compete with algae and thus, limiting algae growth.
Fish also love to have plants because they can hide behind them when needed or just play around it. Yeah, they need entertainment too!
Finally, plants also filter out pollutants and keep your pond clean.
But if you’re stocking fish like koi, they might not be enough for a standalone aerator.
Pros
- Natural
- Filters pollutants
- Improves water clarity
- Suppresses algae growth
- Absorbs excess nutrients
Cons
- Not the best for fish stocking ponds
- Cannot aerate a large pond alone
If you don’t have any preference or simply don’t know which ones to use, I got a few suggestions:
Arrowhead
- Grows easily on shallow water
- Not much demanding
Water sprite
- Great water purifier
- Use excess parts as food for goldfish
Hornwort
- Vigorous
- Tolerates temperature and light fluctuations
Homemade Pond Aerator Without Electricity
It is quite simple and inexpensive to make a DIY homemade pond aerator. The tricky part is the electricity as you need to run a pump at least for your aerator. So you can use either solar or wind power (as discussed above) to operate the pump. Check the video to understand how to make a pond aerator at home, all by yourself –
Parting words
It won’t be an understatement if I say- Oxygen is the key to life. A whole ecosystem is engineered around it. As an owner, it is your responsibility to take care of the pond, and aeration is one of the means to it.
If there is no opportunity to use electricity, then you must know how to aerate a pond without electricity. There is no way you can dump that responsibility elsewhere. Thankfully, my article will ease that burden.
