Mag return resonating sump. How to make it quieter...

[Icebox]

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!!!

I also had some concerns about using a submerged mousepad, so I got one of the sponges that are used in an Aqua-Clear power filter, cut a piece 1/2" thick and use it under the pump. Made it a lot quieter. Others have put a few large glops of silicone right on the sides & bottom of the pump body itself to accomplish the same thing. Just remember to let it cure well first.

Try using a wet/dry filter pad, such as this one:

Great thought Boomer, and LI. those both sounds like great ideas..

How long does it take for silicon to "Cure"?

Thanks bunches.

48 hours minimum at 75 degrees or warmer for 100% cure on silicone

Ahh, thanks Cosmic.
