NICREW UFO Aquarium Air Pump for Fish Tank up to 400 L, Air Aerator Pump Ultra Silent, Oxygen Bubbler with Dual Outlets, Accessories Included, 2.5W

Had this for a few moths now and it's still working well. I wouldn't say it was silent buy it is very quiet and does not vibrate.It's easy to set up and alter the strength of the air flow.Small and discreet, very nice design and great value for money.

Really nice unit . Supplied with hose , air stone , flow back valve & air regulator tap. Very easy set up .. incredibly quiet operation . Unit does not get excessively hot like some others do , great build quality. Great value for money.

Great pump, not loud at all just a small whirring but barely noticeable. Easy to control the airflow to lessen or augment the amount of bubbles.However was looking to place my pump below water level and use the backflow valve but backflow valve arrived faulty only allowing the smallest amount of air through. It’s on top of my tank for now but will need to buy something else to rest it on above water level.

A good little pump, in all fairness.You get everything you'd need: air pump, two stones, two suction holders, two regulators and two back flow valves.I saw that some reviews say it's loud, but some noise is to be expected. That being said it isn't distractingly loud, it's probably as loud as any pump we've owned previously.The air regulators are a bit fiddly - one of the caps fell off when I was setting them up - but they do the job in terms of controlling the output.The air stones seem good. Good bubble streams from them.You also get a lot of air line, quite generous in that respect.I have also bought another one of these air pumps (the single output option) for a family member.(And a side note, the fishes seem to enjoy playing in the bubble streams!)

Small but powerful pump, nice and quiet, really happy with item

I bought this to provide agitation to the surface of my aquarium and to run a sponge filter.Setting up was easy, with the exception of a bit of trial and error with the one way valves, but it’s in no way an issue to the set up process.The 2 air stones it comes with are adequate and provide a pleasing display of bubbles. The pressure it puts out is more than enough to run the air stone and the sponge filter.Noise level is a gentle hum which is hardly noticeable and is not noticeable at all with the tv on.My only slight complaint is the that the power cable could do with being longer.For the price this little air pump is a great looking little powerful little pump that I can recommend

Started ok and was fairly quiet but after a few months it suddenly started to sound REALLY loud. Now looking for a replacement

Novice aquarist but finding this pump very good and quiet. Nice lot of bubbles. Very happy. Not very big but works very well.
