by KaMos Yes its loud but that can be fixed
Great filter, but yes it can be loud in terms of the LOUD waterfall sound that comes from the inside of the filter. It can be fixed with some filter foam/floss.
It does have a humming but not any louder than any other filter I have had. An air pump is much louder than this. My only issue was the loud waterfall sound which I fixed..see picture for fix

Rated 1 out of 5 by jstarch Don't waste your money
Was noisy from the beginning and it not only did it not keep the water clean, it became just plain filthy. I did several water changes, rinsed and used new filters, finally resorting to using chemicals and I could never get the water clean. After 2 months it just stopped. Replaced it with a Fluval and in less than 24 hours, the water is clear and my fish are happy.

Rated 1 out of 5 by Dimples311 Quiet Flow my foot!!!!!
This filter is too loud. I have a tank in my office and every time I walk in here I want to scream. Not only is it too loud, it doesn't keep the water crystal clear. Whenever I have a conference call I have to unplug the filter so I can hear my co-workers. I guess you get what you pay for. I wonder if I can take it back?

Rated 1 out of 5 by Sinc Very noisy - get the QuietFlow 30 instead
Quite disappointed in this "QuietFlow" unit. It's extremely noisy, whereas the QuietFlow 30 by the same company is virtually silent.
I suspect this is because the shell of the QuietFlow 30 and 50 are the same, and Aqueon just put a more powerful motor in the QuietFlow 50 without adjusting any other part of the unit, leading to a lot of noise and vibration.
Get the QuietFlow 30 instead. If you have a large tank, get two QuietFlow 30s. (This also helps your tank stay stable in case one unit fails).
