Tetra Whisper Air Pump

I bought a 5 gallon air pump for more than this, and that air pump failed to pump air through 2 2.5gal tanks. So, I went to the overkill side and purchased this. First, though, I want to address some of the other reviews.

NO air pump, I repeat, NO AIR PUMP IS SILENT. If a manufacturer tries to sell you a silent air pump, you need to step back and assess if their project development team has taken remedial physics. Vibrations create sound, which means no silent vibrating air pump diaphragms. According to classical physics, it is physically impossible for that to happen. However, through sound damping and clever material choice, you can make it so that it's close to silent. You'll never actually get there, but you can make it quiet enough to not be heard over the usual white noise of the home.

This air pump is the quietest I've ever gotten my hands on. I live in a building with a constant low level of background noise, and I have to concentrate to pick the pump's quiet hum out. It's well constructed, the rubber feet do a lot in the way of damping sound, and if you have it in a bedroom, wrapping it with a towel makes it practically inaudible. Otherwise, it's a very well built and well functioning pump for its price. You will never find anything as good quality as this and for as low a price as this; I can guarantee it from weeks of searching online.

Pump is whisper quiet. Comes with an inline check valve to adjust the level of output. Works great. Does not come with any hose, or with any tfitings, so these will need to be purchased seperately.

I have this setup on a 20 gallon tall aquarium. It also goes to a standard 10 gallon via a 2-way gang valve. So in essence it would be like connecting two 'bubble' devices up (think air stone plus bubbling treasure chest decoration as an example). The gang valve allows me to compensate for the 10 gallon not being as deep as the 20 gallon. For those interested, it is running a sponge filter in both tanks.

With this set up, it is barely able to keep headway and only produces a minimal amount of bubbles. This is okay for me, since I run fully planted tanks and only need minimal water flow for temp and nutrient distribution. If I was doing two devices in the 20 gallon alone though, I'm not sure it would be powerful enough.

How big of a pump do you need? It's all about depth and has nothing to do with volume ... which is how they are foolishly marketed. It should be clear that a pump will work much better on a 20 gallon long tank than it will on a 20 gallon tall tank due solely to the depth of the water even though they have the same volume.

My biggest complain with this air pump is it isn't quite. It's about the same level of noise that a cheap HOB filter makes while good HOB filters will be far quieter than this thing. It's a constant hum that you can get use to, but will always be there and add to the `background' noise of your house. The best I could compare it to is the kind of noise a refrigerator makes when it is on.

This pump is better than several cheaper ones we've tried, though it does have a larger footprint. Rubber feet are excellent.

I had my doubts about purchasing an air pump for my 16 gallon bow front aquarium. My filter is very quiet and I didn't want to add the additional noise of an air pump, but I wanted to add some circulation to my tank. I was pleasantly surprised with the Whisper air pump. It basically only added a low hum to my tank set up. Very happy. Works great.
