NICREW ナノサイレントアクアリウムエアポンプ ブラック コード付き電動アクアリウムエアレーター アクセサリー付き 最大10ガロンの水槽用 超静音 0.3L/分 1.5ワット

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.

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

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
