How to make Tetra Whisper Air Pump quieter

When using the Tetra Whisper Air Pump, you may notice that it is making a loud buzzing noise. To see how you can potentially fix the loud sound issue with this fish tank product, you can take a look at troubleshooting article from Aquarium Blueprints.

1. The first step you can take is to make sure that you put the Whisper Air Pump on a stable surface as it will vibrate and move around a lot. So, if you have something that moves around and make a lot of noise underneath the pump, then the sound may become too loud.

Moreover, you should avoid butting any small objects near the air pump since its vibration could end up moving the objects around.

2. You may also want to consider putting the air pump on a soft surface as doing so should help reduce the noise level cause by the vibration.

In our case, we put the Tetra Whisper Air Pump on top of a dry soft cloth.

3. It is important to note that the Whisper Air Pump that has been rated for up to 60 gallons or up to 100 gallons come with 2 air outlets. If you leave one of these outlets uncovered, then it will end up making a lot of noise.

In order to prevent this from happening, you can try doing the following:

  • Cut off a small airline tubing.
  • Plug the airline tubing into the air outlet that isn’t currently being used.
  • Plug an air control valve into the other end of the airline tubing. For the 60 gallons and 100 gallons versions of the Tetra Whisper Air Pump, you should get two of these valves included in the packaging.
  • With the air control valve attached, turn the knob clockwise to reduce the air flow in order to make the pump quieter.
  • If you don’t have an air control valve available, then you can use an air stone to plug into the other end of the airline tubing in order to reduce the pump’s noise level.

Keep in mind that the 10 gallons, 20 gallons and 40 gallons versions of the Tetra Whisper Air Pump only come with only one air outlet. So, if you only need one air outlet, then you may want to consider returning the 60 gallons or 100 gallons version of the air pump and then getting the 10 gallons, 20 gallons or 40 gallons version.

4. You may also want to consider putting the air pump inside a cabinet, if possible, as doing so will muzzle most of the buzzing noise it produces.

When putting the Tetra Whisper Air Pump is a cabinet, make sure you leave a little opening for the cabinet as the device will generate a lot of heat. If you don’t, then the heat could build up and cause the air pump to overheat and potentially malfunction.
