Size:Carbon 5-Pack The bio balls and ceramic rings provide biological filtration, removing toxic ammonia and nitrite. The combination of three different filter media work best for your aquarium filtration. Each media is packed in individual mesh bag. Mesh bag allows the precise placement of media and ensure granular media does not travel through pumps and pipes.

A very good deal
I got these to use in my Pet 360 water bowl. The price was a great deal and there is enough that it should last me a year or more. Works great with the reusable filter that i have.
