You will definitely need a bag to put it in a canister. Purigen is really small beads, and will filter thru most filter bags. If your using it in a canister, you can either buy the 100 mL, that comes in a bag already or buy "the bag" that seachem sells.
Purigen needs to be in a bag, regardless of what type of filter you are using. Yes you can use a nylon stocking; cut it down close to your final desired size and just fold it over. I have been doing it that way for years with no problems.
Good luck - that stuff is great.
