This filter is way quieter than my other brand Nano-filter! In fact, I had to place my hand under the spray bar just to make sure it was running it was THAT quiet! Very well made, they even include a cleaning bristle so you can clean off any algae that develops on the spray bar. Will definitely recommend and order again!

This little corner filter is really nice and almost completely silent. The nozzle is adjustable, as is the flow. It's a very attractive filter, taking up very little space in my Waterbox 6g. I recommend this for anyone with nano tanks!
