Hi Brad, do you have a gap between the frame and the tank or the frame and the ceiling? I looked specifically at your thread and it looked to me like it's resting on the tank straight to the ceiling? I thought maybe you were able to get away with this because you have an acrylic tank ... Or maybe you just don't have a bouncy flexy joist like I do. I'm starting to suspect these engineered joists that I have are supposed to be bouncy and flexy. Which is great for reducing noise but not so great in this scenario.

Oh well, I have high hopes for the sister-joists method .. I've gone and bought the lumber but just due to the nature of the work I'm unable to put it up by myself. My wife is about 7.5 months pregnant and suffering from every pregnancy related ailment so I've been .. kind of not asking her for help. I have to wait until some poor unsuspecting other person comes along. The next person to ring my doorbell to tell me about Jehovah's Witnesses or sell me a Calgary Herald is in for a surprise.
