Myself, I have concerns about using products which are not designed

constant water immersion and living creatures.

Max, where in the US do you find this mysterious "glass wool" where you
never know what could be in it? Out of your sofa pillow, perhaps...

Come on, the glass wool which made your skin really itchy (I call it
glass wool, but I don't know what it really was). It was used inside
corner filters, (around the time they invented airstones ;~). If you
can't remember that, then I'm showing my age ( Jim... help

Gee, that was back before tanks made with silicon.
That glass wool was indeed spun glass or spun fibreglass. It worked well
but it was literally a pain to handle. I am sure I still have shards of the
stuff floating around my body.
FYI, I had a serious problem with polyester 'no additive' fibre purchased at
a sewing store. Yes, it was cheaper, but I found I was having a strange
almost jelly like growth in the tanks with this fibre. I contacted the
manufacturer and they politely refused to divulge the exact make up or
processing procedures. I then switched back to the regular aquarium floss,
the strange growth no longer happened, and the fish deaths dropped right
off.
