Automatic Fleece Roll Filter Replacement, 50 Micro, 100mm*25yard | for ROLFIL-5000

Replacement fleece rolls for the Wavereef 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 4 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 filter while your system adjusts to the new level of mechanical filtration.
