FEDOUR 4W Adjustable Aquarium Air Pump, 6L/Min Powerful Fish Tank Air Pump, Quiet Aquarium Aerator Pump for Fish Tank up to 450L

This is a really useful little air pump and ideal for a small tank. It comes with 2 sets of air line, air stones, valves, literally everything you need to set this pump up, it also comes with a small suction cup to stick the air pump to the outside of the tank if needed.No air pump is silent but this one is fairly quiet but the stronger you have the air output the louder the pump is but is bearable compared to other pumps.The output is really good, even on the lowest setting, there is enough air for the aquarium with one stone so the other stone can be added to the filter to add better function to beneficial bacteria.This air pump is a great addition to the tank and would make a handy useful backup air pump for a larger tank if needed for any reason and it's a great price.I would definitely recommend this air pump.

For a budget air pump this is a high quality product. It has two outputs which has a adjustable pressure and also comes with accessories which includes 2 air stone's, 2 pressure taps and silicone hose with hose clips. And is wisper quiet. Very impressive would recomend.

A little noisy but works well

I use this in my 105l Biorb as I felt it needed a bit more flow. The pump is quieter than the bubbles. I like that you can alter the setting as I turn it back a little at night. The tubing could be a little more robust but it is great value for money and easy to set up.

The media could not be loaded.  Love the easiness to set up. I’m hoping that now I have more oxygen in the water that my catfish eggs may survive as we’ve had 2 lots so far-the first set was eaten by mama fish. The tank is thriving and I have some honeys who keep swimming into the flow to be pushed back as they enjoy this. Thanks.

nice. and quiet

Worked well until it stopped pumping air 1 year after purchase.

Good value item with two airstones. Ability to control the airflow easily is great.

Quello che cercavo.
