Oxygen should always be in abundance inside an aquarium. Without proper aeration, fish will not get ample supply of oxygen, which will make them use their gills to take in more water. As a result, they damage their gills in the process.

To stop this from happening, simply install an air pump to get the oxygen circulating inside the tank. A good air pump to use is the Tetra Whisper 10 Air Pump from Pet Store, a uniquely-shaped pump that works powerfully yet quietly. Its patented shape -- a perfect dome -- is designed to contain in sound so it can work without noise. Under the dome are chambers that dampen sound and minimize turbulence to produce a smoothly streaming air, instead of loud bursts of wind. You may have gotten used to the sound of your current air pump now, but you will surely appreciate the peace and quiet this dome-shaped air pump can provide. Also, the much quieter mechanism can calm down even the easily stressed fish.

On top of all those benefits, you get an aesthetically appealing device with a bright blue color that will surely fit in nicely in any tank.

The Tetra Whisper 10 Air Pump comes has different sizes, even for tanks as small as 10 gallons or as big as 100 gallons.

The new Whisper air pump was redesigned from the ground up for silence and performance.  It has many patented features that minimize noise yet allows for a  powerful flow of air.
