I got a big 20 sq ft bag of this filter floss a few weeks ago http://www.bigalspets.com/fish/filte...-20-sq-ft.html
It's working out great in my Aquaclear HOB filters and should last me a loooog time. It's a great value and something I plan to keep buying in the future.
Glad you like it! We use a ton of it in our stores, and any staff that have aquariums use it in their filters as well. Great product at a great price point!
