Review on Hydrofarm Active Aqua Pump Outlets by Shannon Brown

I bought this air pump after reading several reviews on websites which gave it high marks for being very quiet, great performance and low power consumption. However, it seems noisy to me, as expected, most air pumps vibrate, and with the cabinet doors closed I can still hear the vibration from this one. I think it's ok for the price, but after reading it I'm still disappointed that it got such a high rating for low noise. I added cotton around the fixed parts to reduce vibration and that has helped some.
