Description
NanoMat Red Sea
The NanoMat is a compact, plug-and-play automatic fleece roller filter made by Red Sea, aimed at smaller reef or “nano” aquarium setups. It is intended to replace traditional filter socks or pads by continuously advancing fleece to present a fresh filtering surface, thereby maintaining better water clarity over time.
It’s designed to be a drop-in replacement for standard 4-inch filter sock holders and is compatible with Red Sea’s MAX NANO G2 systems (and some REEFER G2 systems) that accept 4" filter socks.
NanoMat is more basic than its “bigger brother” systems (like ReefMat) in that it does not require or support app connectivity; its operation is handled by an internal processor and sensors.
Here are the major features and technical specs of NanoMat:
Compatibility: Fits standard 4-inch filter sock holders, and works in the rear sump of MAX NANO G2 systems.
Maximum Flow Capacity: Up to ~250 gallons per hour (≈ 950 liters/hour)
Recommended System Volume: Up to about 53 gallons (≈ 200 liters)
Fleece Mat Width: ~2.2 inches (≈ 5.5 cm)
Fleece Mat Length per Roll: ~59 feet (≈ 18 meters)
Dimensions: ~3.5 × 3.5 × 16.1 inches (≈ 10 × 9 × 41 cm)
Roll Material: Non-woven polyester fleece, ~50 g/m², engineered for high flow and skimmer-friendly filtration.
Drive & Sensor System:
• Processor-controlled drive unit — the motor advances the fleece when needed, on its own.
• Dual solid-state level sensors — one senses when the fleece is blocked and triggers advancement; the other senses high water level (e.g. during maintenance or pump shutdown) and suspends auto-advance to prevent wastage.
• Auto shutdown / auto suspend functions to avoid unnecessary fleece usage when conditions (like high water) indicate it shouldn’t advance.Indicators / Feedback: LED indicators to show whether auto-advance is suspended (e.g. due to high water) or if the fleece is jammed.

The NanoMat by Red Sea
- Water in the sump or filter chamber flows through the fleece roll as it would with a traditional filter sock or pad. Suspended solids, fine particulates, uneaten food, and other detritus are trapped on the fleece surface.
As the fleece surface becomes clogged, flow is restricted. The primary level sensor detects this increased resistance (or water backing up) and signals the drive unit to advance the roll, moving to a fresh section of fleece.
The secondary (high-water) sensor stops automatic advancement if the water level gets high (such as during feeding when pumps may be off) to avoid over-rolling when not needed.
The fleece roll typically lasts a few weeks (often ~4 weeks under moderate conditions), though actual lifetime depends on bioload, feeding, flow, and particulate loading.
When a roll is used up, it is replaced with a new roll via the “easy fleece-mat replacement” design.

Advantages of using NanoMat
Reduced Maintenance / Consistent Clarity — Because the media advances automatically, you get consistent filtration without having to manually clean or swap socks every few days.
Plug & Play Installation — It is relatively easy to install: just remove the filter sock holder (in supported systems) and drop in NanoMat.
High Flow Handling — Designed to allow higher flow while still filtering particulates, helping avoid bottlenecking the sump return.
Skimmer Compatibility — The fleece is designed to be friendly to protein skimmers (i.e. not releasing lots of particles downstream).
Autonomous Operation — With processor control and sensors, it does not require external control or app connectivity, making it simpler and more reliable for many users.
Limitations
Because it is a “nano” version, its capacity and flow constraints limit it to smaller systems (≈ up to 200 L) — it’s not intended for very large or heavily stocked reef systems.
Since it doesn’t connect to any external controller or app, you won’t get alerts or remote monitoring — you must rely on observing the system and checking the unit manually.
The fleece roll, once exhausted, must be replaced manually; you must keep spare fleece rolls available.
The system depends on correct positioning, sensor calibration, and stable water levels; extreme fluctuations or poor installation can hinder its performance.
It is specified for saltwater (marine / reef) systems only, not for freshwater usage.
