Is foam toxic to inverts?

[pirate2876]

Quick question; I needed a place to put my probes and I ended up using a small block of foam from an insulation cooler as a floatie for my probes. Is there any danger of the foam disintegrating or leaching something?

Hard to say with certainty, but I think it is unlikely to be a problem. :)

I've seen some places use pool noodle cut outs to suspend mangrove seeds. Perhaps that's buoyant enough for your equipment. Don't insulation foams have a sliver of metal that peels off on the outsides?

This foam is from a styro shipping box with no liner. The pool noodle idea is great though. I'm going to do that instead, thanks!
