Pump silencing question

[Vagabond]

I have an in sump skimmer, Euroreef ES5-3 running on a dolphin DP560 pump.

I love the skimmer but the vibratory noise from the pump is a liitle loud.

Anybody have some reef safe solotions for padding between the pump and the glass bottom of my sump to reduce noice/vibration.

I was thinking a piece of neoprene but did not know if this would degrade over time and be toxic.

Ideas/suggestions/experience appreciated

TIA

I use foam filter pads man (Aquaclear 300). Seems to work fine.

You can also use a large media bag with some fine aregonite in it as a sand bag under it. Sand is the bomb for deadening viabration and noise. (That's if you have the room for a small flat sandbag.)

Thanks for the ideas guys

I have a couple extra filter socks kicking around so I will try Gary's sandbag idea first. I love to try ideas I haven't heard before and there's lots of room in my the sump.

Cheers

Sorry to bring this really old thread back to life. Would like to know what new & successful, DIY ideas anyone might have. I have the sand, what would be the best thing to keep it contained. I have a Euroreef RS135 that I would like to sound dampen, obviously reef safe. I have filter floss, wouldn't I need to change it out every so often?

You can go to the dollar store and buy some silicone hot mats.

I hear filter pads work very well for this application.

Nice necro, only 10+ years too late

I raise my pumps off the ground with a DIY stand using some pvc plumbing as the feet and attaching it to a piece of light diffuser plastic. Works really well, and allows for flow underneath it, and you can raise it as little or as high as you wish. I have it on both my skimmer pump and return pump, and makes them virtually silent.
