Air handler poly mat for filter material!?!

[Lousybreed]

See my pic. Big roll of untreated poly air filter mat. It’s really cheap. Like $68 for a 90’ by 24” roll. It is not treated by tactifier I am wondering if anyone has ever used this stuff in a reef tank I am also wondering the best way to test to see if it’s reef safe. I am hoping someone has tried this before. Any experiences with it?

I don't see why it would be a problem so long as it's not treated with anything,

You could set up a 5 or 10 gallon tank with some in it and testing if it leaches anything.

Yeah I am starting to think that is a good way to go on this.
