thank you for this thread and response.
I also got some blasting sand and noticed alot of those broken wire pieces and was getting a little worried if I should use or thrash the blasting sand. Those wire strands are not magnetic so... . lol
now I have confidence that my blasting sand with those alien pieces are just fine.
Started out, thinking it's a 5gal. tank chore for my grandkid want, now, it's turned into a expensive hobby that I've got only myself to blame fer.
