Review on Coralife 05146 SL 65 Super Luft by Elli Navarro

I read the reviews and knew it wasn't going to be 'quiet' but I wasn't prepared for how loud it really is. Maybe it'll do a great job. Maybe it's better than diaphragm pumps. That's all well and good, but if you can't be within 30 feet of the tank because it's so loud, it's a waste of time. We put it in a tank cabinet and turned it on with the air valves closed. The noise coming from the pump was the equivalent of a loud TV. It is not possible to have a normal conversation in the same room with this pump when it is running. As a test, I turned it on, closed the cabinet and called the speakerphone about 10 feet from the tank and the person on the other line asked me what the noise was without my prompting. While this could well be a solid product for what it's supposed to do, in most situations it's too loud to be practical.
