Red Sea NanoMat Fleece Roll (2 In Pack)
The genuine Red Sea fleece refill for the NanoMat roller filter, two rolls of the same 50gsm polyester media the unit ships with. Keep a spare pack handy so you are never caught mid-roll.
Key features
- Genuine Red Sea media – same 50gsm non-woven polyester fleece fitted from new, so filtration stays consistent.
- High-flow, skimmer-friendly weave – traps fine particulate without choking flow or stripping proteins.
- Two rolls per pack – covers a couple of roll changes before reordering.

Will it fit my NanoMat?
Yes. This roll is sized for the Red Sea NanoMat, the compact roller that fits a standard 4 inch filter sock holder or the rear sump of MAX NANO G2 and REEFER G2 systems. It does not fit the larger ReefMat 250, 500 or 1200, which use wider rolls (8cm, 11.3cm and 17cm). If listed here as the "Nano ReefMat Fleece Roll", that is an earlier name for the same NanoMat roll.
What's included
Two rolls of NanoMat fleece media.
Not included: the NanoMat unit, take-up spool or power supply.
Care and maintenance
Roll life depends on bioload and feeding, from a few weeks to over a month, so keep a spare pack on hand. Store rolls dry and out of direct sunlight.
Common questions
Will this fit a ReefMat 250, 500 or 1200?
No. Those units use wider rolls and need a different refill.
Is this the same as the "Nano ReefMat" roll sold elsewhere on this site?
Yes. "Nano ReefMat" is an earlier name for the NanoMat, and the fleece roll is the same product.
