I actually found someone selling them on *bay.com for like a dollar, and 90 cent shipping
for w.e reason it didnt show up when I first searched (nylon media bags) took a few tries searching different variations of the same sentence but yea,
this was the description
"12" x 4" Nylon Filter Bag with Draw String for any type of filter system, including power, canister, sump or wet-dry filters.
I purchased a hundred, used 25 for myself and have about 75 available. All are new and work great. First bag ships for only $.95, additional bags ship for only $.20. Ships 1st class mail same or next day of payment. "
sounded aqua safe to me, and no zipper just a draw string
