NICREW Air Pump Aquarium Ultra Quiet <33 dB, Nano Silent Mini Oxygen Pump up to 40 L, Accessories for Fish Tanks, 18 L/H, 1.5 W

The media could not be loaded. Incredibly quiet - can only hear the noise from the bubbles. Despite being small it seems to be very effectively powering a small corner air filter.Really compact and great that it sticks on the side of the tank so you don't need to find any room for it. Perfect for a small aquarium (note it states 40 litres so you'd need something with more power for a bigger tank).

This air pump is absolutely amazing. It is sooo quiet I would say silent for sure! And the amount of bubbles is just as good as larger air pumps that I have brought in the past that sound like I’m plugging in a bus haha. This nano sized air pump is a game changer excellent for quiet rooms like the bedroom. It is well made and excellent value for money. I will buy again for any additional tanks. It looks neat and will fit in small places. The suction cup holds it securely in place. This is the only air pump I ever want to use. Brilliant, again soooo quiet!

Mini device I like it easy to use

After keeping tropicals previously, I decided to install a new aquarium, and one of the biggest problems has always been the noise from the air flow pump. Not only are they usually quite large, they also tend to hum away like a tractor driving you mad and defeating the object of peaceful fish keeping. Not with this one. Super happy with this purchase, it's small and mighty! Easy to set up just plug and go. When I first plugged it in, I thought "uh oh faulty" as there's literally zero sound or vibration from the unit itself. It's only when the air stone is submerged that you see it kick in! Perfect strong air flow, masses of bubbles, fish lively and loving the new addition. I'd say it rivals, if not beats the more expensive on the market. It's supplied with plenty of tubing so you can hide the air stone behind live plants and decor, and the slimline unit itself is tiny and sits perfectly with the suction cup to the outside of the aquarium allowing for cables to be kept tidy and hidden. In use, the only sound is the strong but gentle flow of bubbles which is both relaxing but most importantly not disruptive as the aquarium is in the bedroom. 100% worth the price and would buy again without hesitation!

The media could not be loaded. Firstly, I don’t normally do reviews, but this really deserves a mention! It’s being used in a 125 Ltr tank (way over the recommendation) and I’ve attached a 30mm air curtain. How could it possibly cope? It does!! I have used double sided Velcro to attach to back of my tank. NO additional noise beyond the existing pump! It’s just a feature for me, but no doubt it’s adding some additional oxygen to my setup! Highly recommended.

Excellent little pump. A replacement for my old table top pump. Completely silent and compacted you only can hear the bubbles now.

The media could not be loaded. So small, neat and poweful. Works really well with the Pawfly nano bio sponge filfter. V.quiet (the camera exaggerated the sound volume quite a bit). Much nicer than the old pump that came with the tank. Shrimps and the snail seem happy

Great little air pump, you can attach it to the side of your aquarium with suction cup provided, it is very quiet and strong enough for a 60l sponge filter
