Pond Filter Floss Bio-Media - FFM, FFM2B
- Ribbon type material commonly used in pond filters in place of lava rock
- A flat strapping that is embossed on both sides creating additional surface area for bacteria
- Lightweight, will last indefinitely and has no negative effect on water quality (unlike lava rock)
- Pond builders prefer using Pond Filter Floss Bio-Media in AquaFalls filters since each media bag will weigh 4 lbs. instead of 40 lbs. when filled with lava rock
- Each roll fills two to three MB21 mesh bags (sold separately) and contains approximately 6 cu. ft. of media.
