3W Aquarium Air Pump, 300L/H Silent Adjustable Fish Tank Bubbler, Powerful Oxgen Pump for up to 450L Fish and Turtle Tank

Good little air pump with two air stones which can be regulated to suit fish requirements. When high there is a hum but not too noisy. Was quick and easy to set up and fish seems happy. Would definitely recommend.

So impressed with the quality of this dual air pump. Having purchased similar pumps in the past this one is hands down far superior in terms of 1) Noise level - you can hardly hear it at all, 2) Installation was simple with clear instructions given at every stage, 3) don't be fooled by it's relatively compact size as the power it gives out is great! Also, with the dual air pump because all of the valves you need are included you have the ability to individually change and control the amount of air flowing through each airstone. I couldn't recommend this product more highly & is definitely worth a 5 star review 😊

Brilliant pump, was so impressed with it and it's quiet as well. Very easy to install and works perfectly. Used the stones to aireate the water, much better than what I used to have as the stones are heavy enough to sit on bottom of tank.

Impressive for the price and the pump is quiet but the bubbles are noisy lol so I’m unsure if that’s what people mean when they say it’s noisy. I will add a video of bubbles plus sound in cupboard. My only issue is the difference in the two outlets. It has to be on high to get a small ammount out of one outlet? Does the job just annoyed by this as I would rather have it on low all day to make it quieter.

I got this pump to run an air stone and a filter in a half barrel pond. The pump is inside my summer house/ garden office with the air lines running out through the wall. At the pond end the only sound is bubbles and inside the pump can barely be heard, even on full power, but about 1/3rd power is perfectly adequate. Good price, good value and very quiet. I did purchase some heavier duty air lines because what came with the pump was too short for my needs, but I did know that would be the case in advance. If / when this pump fails I shall most likely replace it with the same

It's great, great quality, the big advantage is that it has two Air hoses, very long, can make 4 hoses out of those two, and the bubbles intensity it's easily adjustable,not to mention that it is like half a price from the local pet shop, doesn't heat up, can easily hide it behind the tank or under the TV unit, noise wise it's not that bad if I turn it to a lower intensity. Can't complain haha, thank you!

Bought this as it was stated silent I understand there would be some noise as this isn’t my first pump but this is far from quiet unfortunately as the tank is in the front room and the tv has to be up high to drowned it out. can’t fault the pressure etc but the noise isn’t quiet I won’t be keeping this pump.

I exchanged the first one I got because I thought it was faulty as the two ports were delivering different volumes of air, only noticeable at low settings. The replacement was the same so assumed it must be normal. And thinking about it, the bubbles produced by separate lines would be dependant on the resistance in those individual lines. different length tubes for instance, duh. And that's why they icled in the set adjustable valves to put in the pipelines, I hadn't tried these. But I fitted them now and it works perfectly. I like how you can adjust the output from barely a bubble to steams, the air-rocks supplied are perfect. Good vibration isolation with rubber feet and very quiet in operation, particularly on low volume. Very pleased with my choice
