Replacement fleece roll for the ReefMat 250 Fleece Roller Filter.

Although specific lifespan will vary according to system parameters such as volume, bio-load, feeding schedule, and initial water quality; each 105' roll of filter fleece should last roughly 5-8 weeks on a moderately stocked reef system. Bare-bottom tanks will typically exhaust rolls at a faster rate. Additionally, usage rate may be significantly higher for the first few weeks after installing a ReefMat while your system adjusts to the new level of mechanical filtration.
