Many fish swimming and playing with bubbles in an aquarium
The best aquarium air pumps are seen and not heard. There’s nothing worse than trying to enjoy your aquarium, and all you can hear is EERRRRRRRRR…
If you’ve ever owned a crappy air pump, you’ll know what I mean.
Now, air pumps aren’t 100% necessary for a successful aquarium, but they can add some nice benefits for you, your fish, and your plant life.
We’ve done quite a bit of research – looking into the benefits you can get from an air pump. Then, at the end, we’ll share with you some of the best aquarium air pumps currently available.

Benefits of Using an Air Pump

We know that air pumps aren’t 100% necessary. There are many aquarists who never use them and have great success.


But, there are still some benefits your tank will receive if you use a quality air pump. Let’s take a look at them…

Increased Oxygen Levels

The main purpose of an air pump is to help oxygenate the water in your aquarium. Some people believe this is due to the bubbles passing through the water, however, this has little effect.


It’s actually down to the extra surface movement which the bubbles create.


The more surface movement you have, the more contact your water has with the air. This results in more oxygen getting into your tank.


Having increased oxygen levels will benefit all aspects of your aquarium. Live plants, fish, and beneficial bacteria will thrive with higher oxygen levels.


This can be especially beneficial in the hot summer months.


As when your water heats up, it’s ability to hold oxygen decreases. Air pumps are good to add that extra that’s needed.

Improved Water Circulation

Water movement is vital to keeping a healthy aquarium. There’s many unseen processes that occur as the water in your tank circulates.


We know increased movement will help oxygenate your water, but, it will also help to:

  • Maintain an even temperature
  • Promote gas exchange
  • Supplement filtration
  • Help to create currents for your fish

Decoration and Play

You might just want to have bubbles in your tank, they can add extra aesthetic qualities. And they can be cool to look at!
What’s best to remember, is that they can’t do any harm and fish tend to enjoy bubbles.
They love to play with them: riding the bubbles up, and then heading back down and do it again – it’s almost like a rollercoaster for them.
Some even use them to massage themselves.

Having an air pump can only benefit your fish and aquarium.

How to Correctly Setup Your Air Pump

Before you go check out some air pumps, I wanted to share with you some tips on how to setup your air pump. So you can avoid unwanted incidents.
Once you have purchased your air pump, you will want to ensure that you install it right.
If it’s located below your aquarium and the power goes out, it’s possible it will create a back siphon of water.
You definitely don’t want that! It will result in breaking your air pump and siphoning all the water in your aquarium onto the floor.
There are two simple ways you can avoid this. Either install your air pump so it’s above your water line, or, use an inexpensive check value.
This will work to stop your water siphoning through the line and into your air pump.
