Things You'll Need:
- Sponge or towel
- Solid surface
-
Step 1
Check the air stones to be sure they are all clean and in good repair. Dirty air stones can cause extra pressure on air pumps, making the pump work harder, which causes more noise. In order to check the condition of the stones, remove them from the water and disconnect them from any air tubing.
-
Step 2
Blow through the air stone with your mouth, blowing air in from the side that attaches to the air tube. If you cannot blow air all the way through the stone, then it is blocked up.
-
Step 3
Dispose of any clogged stones and replace them. It is a good idea to replace air stones once a year to keep them working properly. Air stones have a tendency to get clogged easily with algae, waste and other tank debris. If your tank does not feature an air filter, then change the stones even more frequently, as they will clog more quickly.
-
Step 4
Locate your air pump so that it is above the water surface level. Placing your pump at this level reduces pressure on the pump and in turn minimizes the pump's noise output.
-
Step 5
Place the pump on a solid surface. Hollow containers, thin metals, glass and other flexible materials are likely to vibrate along with the pump, magnifying the noise.
-
Step 6
Place a towel or sponge beneath the pump to help absorb vibrations and act as a sound muffler.
