Even though fish live in the water, it doesn’t mean that they don’t need oxygen in order to breathe. This is why you may need a pump for your aquarium. But, you also need to make sure that you have the right pump for the tank you are using.
Pumps are made for different sized tanks, and if you have a large aquarium, a pump for a 20-gallon tank isn’t going to do a whole lot of good.
Or, maybe you need something to use while transporting fish.
We are going to take a look at a few of the best aquarium pumps for various sized aquariums and uses, so you can get an idea of what you need to look for.

What Does an Air Pump Do in Your Aquarium?
The pump is used to provide oxygen from the atmosphere into the water by disturbing the surface of the water as well as keeping the water circulating.
This water movement helps with the oxygenation of the water and gas exchange at the surface.
Good oxygen circulation is not only beneficial to the fish; it also helps the aquarium bacteria necessary for water filtration to survive.
An air pump will cause the water to circulate so it won’t become stagnant, as well as provide air bubbles and oxygen that your fish and beneficial bacteria need to breathe in to survive.
It does this in two ways;
- Increase surface area
- Improve circulation
How Does a Fish Tank Air Pump Work?

The air pump works in the two following ways.
Increased surface area:
Air pumps work by agitating the surface water, which increases the surface area of the water allowing oxygen to enter the water by way of gas exchange.
Gas exchange occurs at the surface of your tank when your aquarium releases excess carbon dioxide and other gasses into the air and takes in oxygen.
When the air pump creates bubbles, it increases the surface area of the water, allowing your tank to release more carbon dioxide and take in more oxygen.
An air pump also improves circulation by moving oxygenated water from the surface to the bottom of the tank.
This allows carbon dioxide containing water at the bottom of the tank to move up to the surface where it can release the carbon dioxide and take in oxygen.
Most Common Types of Fish Tank Air pumps
Used mostly for decorative purposes such as ornaments and small sponge filters.
High Output Air Pumps
It would be used for very large aquariums that are odd shapes or deep.
Additionally, you would use a high output air pump if you intend to have multiple outputs to multiple devices or aquariums by way of gang valves or connectors.
As it would sound, it’s just an air pump that is powered by a battery. You would use these if traveling in case of power failure or transporting fish.
What size Air Pump Do I need? How to Select the Right Size of Air Pump for Your Aquarium.

When choosing the right air pump for your tank, you need to keep in mind that all air pumps are rated for different sizes of tanks and should be visible on the packaging.
However, keep in mind that this rating is for standard tank sizes, and if you have a tall, long, or hexagon tank, you may need to dig a little deeper.
That said, here are a few things to consider when selecting the right size of an air pump for your aquarium.
- Do you have a deep tank, something deeper than 18” you may need a stronger pump?
- Do you want to run multiple ornaments of one pump?
- Are you using a filter or protein skimmer that requires an air pump?
- The type of air stone you are using may have too much resistance
- If you split the tubing into multiple lines
Choosing the Right Air Pump
While there is no rule when choosing an air pump, it’s always best to pick a slightly larger pump than you think you need.
By selecting a larger air pump, you allow room to expand if needed, and you’ll be sure you have enough pressure to work any equipment or decorations.
For example, check out this post on selecting an air pump for a 5-gallon tank.
These are just a few of the best aquarium pumps that you can get for smaller tanks, as well as for transporting fish from one location to another.
Our top pick will have to be the Tetra Whisper. The price-value ratio you will get from this pump makes this one of the best. It is quieter than most pumps in a similar price range and doesn’t require much maintenance so you won’t need to keep replacing the pump.
