NICREW Nano Silent Aquarium Air Pump Black, Aquarium Aerator with Accessories for Up to 10 Gallon Fish Tank, Super Quiet, 0.3 L/min, 1.5 Watts

Actually quiet. I am very sensitive to the sounds of motors/pumps/etc, and I like for my aquarium to be as quiet as possible. This one is nearly silent, honestly. I tried another, lower cost pump from Amazon and it was so loud. This one is great quality for the money. It pumps out a good amount of air, doesn't use too much power, is quiet. I also love that it comes with a suction cup to attach it to the side of your tank. It's the little things that make a difference, and this pump definitely delivers. I only have mini tanks (5.5 gallons max), so this mini pump is all I need and it's the only brand I will get now

I’m using this nano air pump in a compact 3-liter deep water culture (DWC) hydroponic setup, and it’s been exactly what I needed. It provides just the right amount of aeration to keep the nutrient solution oxygen-rich without creating too much turbulence for the roots.Despite its small size, it performs reliably—and best of all, it’s virtually silent. The piezoelectric ceramic plate design makes it much quieter than traditional air pumps. I have it running continuously, and I barely notice it’s on.Setup was quick and easy. The kit includes the pump, tubing, a check valve, an air stone, and a suction cup—everything you need to get started right out of the box. The suction cup holds well and keeps the pump neatly in place.For small-scale hydroponic systems like mine, this is a solid choice. Quiet, compact, and effective—exactly what I was looking for.

These don't move a lot of air, but they truly are silent. The small amount of air that they do move is more than enough for most nano-aquariums, where the depth isn't so much that it requires more pressure to push that water out of the way. I ended up buying another one of these after realizing how amazingly quiet they are. They've both been running 24x7 for several months now without missing a beat.Highly recommended for small tanks.

Received product and it works amazingly in my 3 gallon set-up. It’s quiet yet powerful and you can adjust the flow of bubbles. It’s quiet yet does NOT come with a wall plug so I’ve got it plugged in however plug is getting warm. There’s no directions that say what wall plugs work best.

Why did you pick this product vs others?:This pump is great, works well, and is very quiet. I combined it with a sponge filter for my fish and it works just like I was hoping! Quietness:Very quiet! Pump quality:Well made and a good size. It comes with a suction cup so you can easily just stick it to the side of the tank for a better aesthetic. Ease of use:Very easy to set up and get going!

Im a new fish mom as of December 2024, this is so silent! The first brand I got, I told my husband there's no way im going to be able to sleep with that.....This one is incredible! I fixed up the tubing to connect to a sponge filter though. My little shrimpies like to hang on it.

BUY IT NOW! This bubbler is SILENT. Not "quiet", but silent. It seriously makes zero noise. We've tried several other bubblers and they all were so noisy. So happy we tried this one. Night and day difference. Buy it.

Worked for about 6 months, then got increasingly louder. I just reordered another one thats louder than the first one. I am sensitive to consistent voices and buzzing. Otherwise, worked great.
