Efficient, high-flow 50 g/m2 filter roll made from non-woven, polyester fleece. Replacement roll for the ReefMat 1200 Auto Filter Roller.Although specific lifespan will vary according to system paramenters such as volume, bio-load, feeding schedule, and initial water quality; each 35m roll of filter fleece is expected to last 5-8 weeks on a moderately stocked 170 gallon 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.SpecificationsLength – 35m / 115ftWidth – 17cm / 6.7″
