My return pump is making the glass tank resonate. If I pick it up a quarter of an inch from the bottom it is just as quiet as it can be. I was thinking about trying to make a silicon pad for the pump to sit on by taking some saran wrap or a Ziploc bag, and filling it with enough silicon to make a little cushion for the pump to sit on. I am afraid of what chemicals a mouse pad may leak into the tank.

Do you have a better idea?
I would love to hear what has worked for you!!!
