Tetra® Whisper 20 UL Air Pump
Great design. Extremely quiet! We are able to hear the soft sound of the water filter and enjoy our tank without the humming, vibrating air pump sound heard with most brands. No need to block the sound or hide the pump. I cannot stress enough how quiet this pump is! Fabulous!

The pump is incredibly loud
The reason I gave it two stars is because it's relatively inexpensive and works as it should. The downside is that it's so incredibly loud. I can hear the hum over my television or music, even when the volume is cranked. What's worse is that it's called the 'whisper' when it does anything but.

My Tetra whisper 100 worked for less than 2 yrs
It is generally a pump that can not last long. My pump suddenly lost pressure and then by opening it up, I found both of the rubber diaphragms cracked and teared. I thought i,m still cover under warranty for less than 2 years. However, the warranty specifically stated of not covering any rubber parts.

Tetra air pump
This product works great in my 10 gallon aquarium. It makes lots of bubbles and has a very affective airflow. I recommend this to anyone with an aquarium.
