Is 100% Polyester Pillow Stuffing Safe To Use In A Filter? SOLVED.

  hello.

I was wondering if anyone has use pillow stuffing in their tank before rather than paying lots from a fish shop for a sheet. I've read a few people buy a pillow with 100% polyester or a bag of the stuffing as it's great for removing the fine particles and crystal clear water. I just don't want to buy the wrong one as I've read it's gotta be 100% polyester, not fire retardant and no additives. I've seen some toy stuffing bags has anyone used them or know if there ok?
Thanks maria

You can get a 10 metre by 0.61 metre roll of pond filter wool for £12.95 including post from EBay. That would last for years and so I don't think it's worth messing about with other types and taking the risk.

Pond stuff is basically the same as aquarium stuff, it's just that their filters use a lot more so it's sold in bulk. And as with most things, smaller packs work out more expensive pro rata.
