AQQA Aquarium Air Pump, Quiet Powerful Fish Tank Air Pump 3W/6W/10W with Stainless Steel Dual Outlet, Adjustable Oxygen Aerator Pump with Air Stone Bubbler for Fish Tank Up to 200 Gallon 3W (Tubby)

At max on a 150 gallon tank this thing keeps the fix a little to busy. At max the pump dose make the slightest little sound but not enough to ba able to hear it. It is absolutely the most quiet pump I have ever owned. The amount of air it puts out is too much but that is a good thing! She. You turn the air flow down it fills like it is actually restricting power not air. The pump run completely silent once you turn it down a hair and the air flow is still a little to high for my tank. I run it about 1/2 to 3/4 power and love how quiet it is and how much air it is capable of putting off. Out of all the air pumps I have had in 30 years this thing amazed me

This bubbler is very quiet and pushes out a lot of air. It is well built and sturdy. I like the fact that it comes with enough hose for the 2 bubble stones included with it. Definitely worth the money

Really like this air pump. Very quiet and the best part it is adjustable.Looks nice and works well.Would buy again!

What a fantastic pump!! This is by far the best pump and value for money one i have had in over 30 years of fish keeping. before this i had the whisper 150 on this aquarium and it had enough power to just power one 4" disk stone and 1 standard ball stone. I was going to replace this with the whisper 200 but this was $114!!So i thought i would give this ago, really surprised by it. Not only does it look great and modern (shame for me as its inside a cupboard) but super quiet and the power from it is insane! it is powering 2 of the 4" disks and i have not even got it on full power i have had to turn the power down!I will be ordering another one for my other tanks!

Works very well, I enjoy the fact that it comes with an air stone and line. The adjustable dial for power is a great feature. Only complaint here is vibration is loud at night, but I also don’t have it inside the cabinet

I replaced a pump I had purchased from Petco. We had a power outage and needed an air pump that we could run from our backup power. The old pump was super noisy. So once or power came back, I shopped around for something better for the long run. This has great reviews so I tried it. It is great! More powerful, so the bubbles look really good. And yet it is almost silent. It sits under the cabinet, so you don't hear anything other than maybe a feint hum if you really listen hard. That's amazing, considering how powerful this pump is. I also like that it is adjustable. Very easy to just turn it to it down. I found the sweet spot where it drives tons of bubbles without making any loud noise. High recommend.

Very good air pump , works well and is extremely quiet great value and durable.

Currently using this air pump on a 3 gallon fry tank, does pretty well, I'm going to transfer it to my main 45 gallon display tank soon, the knob turns the pump off if you turn it all the way down, haven't had one that has this feature. Its about the size of a large candle jar. The suction cup feet also help isolate the vibrations and make the hum of this pump really low.
