Pump silencing question

[rishu_pepper]

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.

If you install some soft, silicone tubing between the out of the pump and the hard pvc plumbing, the pump will be silent as well. That is if the pump hangs from the pvc. Keeping it off the bottom will help a lot if the sand trick doesn't work. And the silicone tubing keeps vibrations from running up the pvc

I just reread my post,,, it is very misleading. I have a Euroreef RS135 that is sitting on the sump bottom & causing a humming sound. What I would like to know is, what can I use for a "sandbag" if I make one. I have filter floss, if I use that, wouldn't I have to change it out every once in a while? I am hoping for something a bit more permanent,,,,,, I have seen that some people use neoprene mouse pads or silicone oven pads (from the dollar store), are these reef safe?

I don't know about neoprene, but they make wetsuits out of that. You would think that a diver, wearing a suit, would not be exposing his skin, to a carcinogen nor a poison. The suit makers would not be in business long.
Oven mitts: would you wear a mitt and pull an apple pie out of the oven, accidentally touch the pie, and then eat it if it had a poison? The tank is sealed with 100% silicone, and if the mitts say the same, they would be good in the tank.

Woah, decade old thread!!! Nice!

I had a EuroReef that was pretty noisy, so I turned it over and put a little blob of silicone on 4 corners of the bottom of the skimmer body and 4 corners of the bottom of the pump and let it dry before putting it back in the sump. Worked like a charm.
