...if you only use one of the two outputs(like I do), put a piece of hose onto the unused outlet it will muffle the noise it makes[I don't know why they don't tell you this in the pump instructions!]. If both outlets have hoses on them, whether they are in the water or not, this will be a quiet air pump. Having two outputs is great, you could easily feed two 30 gal tanks with this, and it seems like this could handle a 100 gal tank.Also!: Make sure to position your bubbles emitting from your stone/bubblewall NOT near(under) your filter intake. The intake will take in the air bubbles and cause significant noise as it spits them out up near the filter[gheez, why don't they tell you this in the pump instructions!]. With a quiet pump and keeping your air bubbles away from the filter intake, you should have a system quiet enough to sleep next to. Therefore I don't recommend using a full length back bubble wall with a top filter, as the filter will take in the bubbles and cause noise.
Whatever you do, don't buy Top Fin pumps,...they're cheap and cheaply made too noisy. Both Tetra Whisper and Rena brands have superior quiet engineering.
After all the numerous mixed reviews, I decided to take a chance and get this air pump anyway, and I'm glad I did.
This pump, as the title says, is surprisingly quiet, the sound of the bubbles and the waves in my tank are actually louder than this pump, and I'm not exaggerating when I say that. I have an old, square shape, Aquaculture pump that was bugging me it was so loud. The Tetra Whisper pump emits a very, almost unnoticed hum. The pump has 2 outakes and comes included with the following:
The pump of course, instructions , 1T-adapter; 2 knobs/valves that help regulate the amount of bubbles you feed into the aquarium by increasing/decreasing air flow. This is actually perfect for those like me with a smaller tank, even though I have a 50 GAL, I don't have to have bubbles at full blast.
I had a problem with my wave maker stirring bubbles all over the place, but now with this new pump, I can have less bubbles in the area near the powerheads hooked to my wave maker. I'm currently using this pump with these: Elite 1-Inch Cylinder Air Stone, 4-Pack and so far, so good. Let the stones soak in your tank for at least 10 minutes before using them.
Some people recomend keeping the pump above water level, but in my 12 years of keeping aquariums I've never done that; just make sure you create a "drip loop" for the power cord with a screw or a push pin, so if water for some reason finds its way down, it will hang and drip at the loop and not reach the AC plug. You may also want to get these: 2 PCS Non-return Check Valves for Aquarium Air Pump to keep water from going into the pump during water changes or power outages.
If you ask me if I have any complaints about this pump, I'd say its size, but that's a minor issue for me, the dome shape of the pump was intentionally designed to reduce the amount of noise it makes, and it works.
The pump measurements are as follow:
7.5 inches long, 4.5 inches wide and 3 inches high.
Overall, I'm very pleased with my purchase, the pump is well built, high quality and made to last. The best feature of course, its almost silent operation, I don't have to crank the volume up on my TV anymore.
One last tip, if you want this pump, or any other pump to make less noise, place it on top of a thick sock or an old fashioned mouse pad. That should absorb some of the vibrations.

My first aquarium pump was a Wal-Mart special. I had it running two decorations, and one side fizzled out. When I went to investigate the problem the air output nozzle had cracked and broken off.Today I got my Tetra Whisper pump. I plugged this baby in and was pleasantly surprised. Air is now gushing out of my decorations and my aquarium feels healthier already. The pump is very quiet, and I cannot hear the pump over the sound of trickling water coming from my filter. The pump came with two airline regulators and a hose T valve.
I want to add more air to my tank like a bubble wand, and I will definitely look into another Tetra Pump.
