The following is a question that was submitted by one of our TFCG community members.
“Hello, I just purchased a 5 gallon tank, what’s the best air pump for a 5 gallon tank?”
Selecting an air pump is pretty simple.
When picking out an air pump try to select a pump that is rated slightly higher than the size of your tank.
For a 5 gallon tank an air pump rated for 10 gallons would be perfect. The Tetra Whisper is a great filter you could use.
Getting a larger air pump gives you some options:
- You can use two-way valves if you want to split the tubes and have multiple air stones.
- You can use larger stones, sponge filters or pneumatic decor.

Keep in mind the depth of your tank is the most important factor when selecting an air pump.
As an example: the deeper it is to the bottom of the tank, the harder the pump will need to work to push the air down to the stone.
If you plan on having a taller tank you may need a pump with a higher rating due to the increase in depth.
Also, the more you split your tubing, the less air will reach each stone.
If you’re like most, you likely have a typical 5-gallon tank and plan on running only one air stone and/or Sponge Filter.
If that is the case, my personal favorite is the Tetra Whisper Air Pump series.
They are quiet and in my opinion one of the best air pumps for a 5-gallon tank.
However, they are not as silent as the name would suggest, but they are quieter than most other air pumps.
Tip: If you find that you still hear vibrations or noises from your pump, try placing a hand cloth underneath the pump, this will help dampen the noise/vibrations.
