Title: Too loud
Review: Way too loud for me. I used mine on a 46 gal tank, ran 2 lines to air stones. Placed it in a closed cabinet below along with a silent Fluval 306. LOUD. Placed it on foam pad to reduce transmitted vibration and harmonics, then wrapped it in several layers of foam, nothing helped. Hung it from the back of the tank wrapped up, no good. Finally took it apart, nothing was broken or loose, nicely made in fact, but I guess the basic design gets stretched when pumping this much air. It did pump a decent amount of air.Of course, doing all this I missed return date by 2 days.
