Fluval Aquarium Air Pump

Its an air pump that does exactly what it says. I have a reef tank which doesn't need one but I bought it for when I dose my tank and it goes cloudy. I have mine hanging on the wall.Noise level does seem to be quite. (air pumps are not silent)Build quality looks very good.Adjustable flow control doesn't seem that great as its not much difference between min and max. (Could be my air stone tho)It is also energy efficient another reason why I bought it.Update = this pump has just got very noisy and I don't know why. Even on a sponge it is noisy. If you hold it the sound is fine. Do not buy this if you intend to leave it on all the time.

Good quality, sturdy and produces lots of bubbles. The only downside is it’s incredibly noisy.

Too loud for the money but works fine.
