Aquarium Filter Floss and Wadding
Not for your fishes' dental hygiene! Filter floss and wadding are time-honored mechanical filter media. The irregular pores and gaps created by wadded up filter floss will trap most of the particles and debris pumped through your filter, cleaning your water and protecting chemical and biological media from becoming quickly clogged. As a plus, you can cut your floss and wadding to any amount and stuff it into any size or type of space, depending on your aquarium setup.
