Saw this stuff at Hobby Lobby for a reasonable price and was wondering if it's aquarium safe. It says 'non-allergenic' which I assume is the same as hypoallergenic...

It's probably safe, but no way to know for sure.

So I posted in a DIY Facebook group and a guy responded (with photo proof) that he's been using the foam material in his sponge filters for a while with no ill side effects. Guess it's worth a try...
