Owning an aquarium is a very enriching and entertaining experience. No matter the kind of animal that lives there, we can bet you spend hours simply staring at your little friends and admiring their beautiful world. While you can save money on buying decorations and other items of that sort, you definitely need the right aquarium air pump. Air pumps play an essential role in all aquariums, and they have an effect on your pets.
Unfortunately, although aquariums are wonderfully mesmerizing, they also tend to cost quite a bit. Many pet owners compare them to a bottomless well — there is always something else to buy. The upside? You don’t need all of it at once, so you can assemble your aquarium at your own pace.
For aquarium owners, both beginners and seasoned veterans, picking an air pump is a bit of chore. We’ve come to the rescue. Keep reading to learn all about the best aquarium air pumps in 2021.
How Do I Choose An Aquarium Air Pump?
While we’ve done the research for you and gathered nine of the best aquarium air pumps, you should still be aware of a few things before you shop. We want you to get the best aquarium air pump for YOU, and only you know your exact needs and wishes. Check out some things to be mindful of when you get a new air pump for aquariums.
This is a big one. Even the best air pumps tend to make quite a bit of noise. If your fish tank is located in the bedroom, you will have to pay a lot of attention to how quiet the pump is. Fortunately, the manufacturers of air pumps are aware of this issue and there are many models with low noise levels.
For smaller tanks, this is a non-issue. However, if your aquarium is sizeable, you need to pay attention to the air flow capacity. For big tanks, you may have to buy more than one pump or simply invest in a big model. Luckily, there are air pumps of all shapes and sizes, so you’re sure to find something that suits you. Air flow in air pumps is also affected by deep water. The deeper the tank, the more airflow is required.
When buying an air pump, you need to either have your tank all planned out, or you need to be prepared for compromise in the future. Some aquarium air pumps only come with a single connection point. This is fine in smaller tanks and/or if you don’t care for many pieces of decor. However, a bigger tank might require a pump with multiple connection points.
This is especially important if you want to use your air pump to decorate the tank. Things such as an air stone, an under gravel filter, or a treasure chest will all require a connection. Keep that in mind when you shop.

Is it Necessary To Have An Air Pump in The Aquarium?
This is a question many fish tank owners ask themselves. Do you really need an air pump? Will your fish survive without one? The short answer is: no, an air pump is not required, and your fish MIGHT be alright without it. Sounds ominous? That’s because an air pump, while not a necessity, is still a very welcome addition to your aquarium.
Air pumps serve a dual purpose. First and foremost, they ensure that your tank’s concentration of oxygen is at an appropriate level. This can be done without an air pump too, as some tanks maintain adequate water movement due to their surface agitation. To make that happen, you’d have to use external filters.
The second purpose of an air pump for aquarium is to force the water in your tank through a filter. An air pump will produce bubbles in your tank, which will then force the water up the uplift tubes. This pulls it through the filter. In a large tank, you may have powerheads that perform a similar function.
However, keep in mind that a lot of fish tanks don’t have the air circulation required in order to skip an air pump. That’s why it’s better to be safe than sorry and get one for your pets.
Some benefits of using an air pump include:
- Surface agitation. Air pumps improve the gas exchange in your fish tank, increasing the amount of oxygen. This results in your fish being happier and healthier. If your fish seem to be swimming near the top of the tank and gasping for air, you definitely need an air pump.
If the gas exchange in your tank is not sufficient, the surface of the aquarium may be very still or even completely still. That is also a tell-tale sign that you urgently need an air pump.
- It can power a sponge filter. This type of filter is powered by the air bubbles that your air pump and/or air stone generates. As the water from the bottom of your tank is sucked into the filter, it comes back out spreading beneficial bacteria. This will contribute to breaking the ammonia in your tank. Such filters also improve surface agitation.
- Decoration. Decorating an aquarium is a hobby in and of itself. We’ve all seen air bubbles used for decoration in a water tank, and with an air pump, you too can get creative and make your tank stand out.
As you can see, while an air pump is not necessary for all aquariums, it’s an improvement in most of them. It’s also a must-have for some fish tanks.
If you’re a beginner, your knowledge of air pumps is quite sufficient by now, but there are still new things to learn. If you’re an expert, you may know a lot more, but questions tend to pop up fully unexpected. We’re here to wash away your doubts before you get your new air pump, so check out our quick FAQ section!
How do I reduce the noise in my aquarium air pump?
If your air pump has gotten noisy & it’s driving you crazy, there are steps you can take before a replacement becomes necessary. With a few small changes, you might be able to improve the situation by miles and miles.
In order to reduce the noise in your aquarium air pump, try the following steps:
- Make sure to keep the air pump on a higher surface, above the water level in the aquarium. This contributes to less pressure, a better airflow, and of course, noise reduction. This method also helps if your air pump fails or suffers from a power outage. If that were to happen, the water might be siphoned back into the airline if you kept the pump lower than the water. However, it’s easy enough to avoid if you stick to this step.
- Clean the air stones frequently. If you use air stones, you need to remember that they require regular cleaning. As they are responsible for spreading the oxygen in the tank, they need to be kept clean. Otherwise, they may become clogged & lower the performance of your pump.
- Remember to place the air pump on a solid surface. If you keep it on a hollow container, such as a box or a shelf with drawers, the noise will get worse. This is because the vibrations caused by the hollow surface below would only increase noise levels.
- Utilize a soft surface, such as a towel or a blanket. Most air pumps have rubber feet that remove the risk of vibrating, but it doesn’t hurt to make that even lower.
How big of an air pump do I need aquarium?
Only you can know this, as only you know your fish tank size. If you’re not quite sure, it’s time to take precise measurements, grab your calculator, and do the math.
As a general rule of thumb, to pick the right size of the air pump for your fish tank, you need to check the output of the device. Your new air pump should provide at least 0.033 liters of air per minute per gallon of water.
Air pumps, while not always an absolute necessity, can bring a lot of quality of life to your little fish friends. Moreover, in some tanks, having the best aquarium air pumps is simply crucial. Observe and take note of the behavior of your fish — they may be starved for some oxygen.
Whether you must have one or simply want to, take your time in picking the best pump for aquarium. Your fish will feel better than ever when taken care of so thoroughly!
