So I went to WallyWorld to get some Poly-Fill to pack into my canisters and I heard it comes in sheets which I like. So I picked up some of this high-loft batting after examining it to make sure it was free of adulterants. Now, looking at the batting, then looking back at my aquarium, I do not feel confident enough as to the 100% polyester content stated on the label. I am worried that it contains flame-retardants or some other chemicals that are not listed on the package. Given that this is the batting available at WM, there are either a number of people using it or its toxic and nobody uses it.
It looks like this:

I managed to find the answer to my question in case anyone else had the same concern. The Fairfield company does not chemically treat any of its products:

Should've gone straight to the horses mouth in the first place.

I've been using Walmart batting for years without any problems.
