Using 266 gph with UV in a 55 gallon aquarium. I don't even listen. He emptied the tank overnight. But I needed a precise directional output flow, so I bought the "Directional Return All Back Jet Volumetric Assembly". This allows the flow to be directed both up/down and side-to-side. It's long/deep enough that there isn't a sound when the water level drops, which several reviewers complained about. In addition, it has a tiny opening to prevent the siphon from flowing back in the event of a power failure. Overall a great system and I will buy another one.
