Red Sea Nano Mat Fleece Roll x2

The Red Sea NanoMat Fleece Roll x2 pack provides two replacement rolls of non-woven polyester fleece designed for use with a fleece-roller filter (such as the Red Sea NanoMat). Each roll delivers fine mechanical filtration by trapping detritus, uneaten food, suspended waste and fine particles before they begin to break down and degrade water quality. When fitted correctly, the fleece roll helps keep aquarium water crystal-clear and reduces nutrient buildup, while the dual-pack gives you two complete replacement rolls so you’re ready for multiple maintenance cycles.
