Red Sea NanoMat Fleece Roller Filter

The Red Sea NanoMat is an automated fleece roller filter designed for nano and small reef systems up to 53 gallons. It's a drop-in replacement for standard 4" filter socks and fits perfectly in the rear sump of the Red Sea Max Nano G2 all-in-one. The smart drive unit automatically advances the fleece roll when it detects a blockage, so your water stays crystal clear without you ever swapping another dirty sock.

How long does one NanoMat fleece roll last?
Roughly 4 weeks of continuous use, but it varies with bio-load and feeding. The unit automatically advances the roll as the fleece gets dirty.

Does the NanoMat need Wi-Fi or the ReefBeat app?
No. Unlike the larger ReefMat 250/500/1200, the NanoMat is standalone — no app, no connectivity required.

Will it fit my sump?
If your sump chamber accepts a standard 4" filter sock, the NanoMat drops right in. It's also purpose-built for the rear sump of the Red Sea Max Nano G2.
