Polystyrene - Reef Safe?

[xxBarneyxx]

Well I have finnally got around to getting the sump running on the tank and just mixing up the salt water in there now. The return pump is really loud though as it is vibrating against the glass.

I was wondering if polystyrene is reef safe? If it is I can get a block to go under the pump to dampen the vibrations.

If its not what also could I use to stop the pump vibrating?

I don't know if this is a daft idea or not but what about filter media, could you stand it on a sponge.
What about something like this [URL="http/cgi.ebay.co.uk/Water-filter-sponge-...%3A3%7C294%3A24"]http/cgi.ebay.co.uk/Water-filter-sponge-...%3A3%7C294%3A24[/URL]
or this http/cgi.ebay.co.uk/Biosponge-filter-med...%3A1%7C294%3A24

Actually thats a really good idea. Never thought of that but some foam filter media would work great.

Thanks

Polystyrene is reef safe. It's want the importers and TMC use to get sponges and hard corals to the LFS in one piece
