NICREW Nano Silent Aquarium Air Pump Aquarium Air Pump Aquarium Aerator with Accessories for up to 10 Gallons Fish Tank Super Quiet 0.3 L/min 1.5 Watt

very cheap and actually noisy and broke minutes after using it.

Too much requirements to use it. Make product not good for me. First 110v ac, second should be up of air output, need valve to stop water, not powerfull, noise is too much to put the aquarium in bedroom. Not returnable easily

I am incredibly impressed with how silent this NICREW nano aquarium air pump actually is; I can barely hear it even when sitting right next to the tank. The suction cup mounting keeps it securely in place and further dampens any vibration against the glass. Despite its compact size, it provides a steady, strong stream of bubbles that is perfect for my 5-gallon planted tank. It comes with all the necessary accessories, including the air stone and tubing, making setup a breeze. It's an energy-efficient and highly reliable little pump that is a must-have for anyone looking for a truly quiet aeration solution for a small aquarium or fish bowl.

Very surprised with how quiet this pump actually is!! It is absolutely silent, to the point that we don't hear anything but bubbles in the water when the rest of the house is shut down. The air flow is decent enough to give good aeration & be used with a filter, but wouldn't work for anything larger than a 10gal. Wish they made this pump for a 40 gal, because we are adding another tank in another room. It was very easy to use and set up , my 4 year old helped & figured it out. It suctions nicely to back of tank and hasn't fallen yet in weeks. I do press it on once a week, just in case. Update: there is a low buzzing that has begun to happen from time to time from the pump, which is not silent, but not loud either. It’s manageable while remaining quiet (just not silent when that happens anymore). Still a great pump that works very well , strong pump. Still want one for a 40+ gal, holding out hope.

I've had this pump for almost two years. It's still super quiet and works like the day I bought it. The suction cup that is supposed to stick it to the tank doesn't do a great job, so I've just laid the pump behind the tank.

Great value for the price, makes slight noise when you’re a foot away from it but otherwise nice and quiet

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.
