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)

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!

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.

This air pump is OVERPOWERED. Quietest one I’ve used. I will never buy a different brand ever again. I am SOLD on these. I love how adjustable they are and that you don’t need to actually unplug the pump to turn it off

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.

I have the 10W model. It's surprisingly small and looks pretty nice for what it is. Putting it together is not too difficult; I needed to cut the tubes to add the filter since the only space for the pump was below the tank.It's very powerful and very loud. At max power, there's a high pitched hum. But, that's not a huge deal compared to how loud the bubbles were, even at ~50% power. It is convenient that it has a knob so that you can turn it down, but I ultimately moved my whole setup to a different room.

Very quiet and effective. I've been using it for about 5 months and it's running same as when first used. Definitely worth the money.

Really nice air pump adjustable which is great for my solar system. Seems to be good quality. Also very quiet. better then any tetra pumps I’ve found for sure

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
