generic 67525 Springflo SF01 Bio Filter Media — Over 190 sq. ft. Surface Area

Over 190 sq. ft. of active surface area per box in a redesigned Springflo SF01 media that boosts biological filtration. Simply hold and pull from the center and the roll will uncoil by itself — use the amount you need and keep the remainder stored; it also has a long shelf life. Delivers an excellent environment for breaking down waste in fish ponds and is an easy retrofit for older filters that currently use filtermat, gravel, bio-balls, or floss. Maintenance is quick and straightforward: no soap, scrubbing, hot water or chemicals required.
