Red Sea ReefMat 250 Fleece Roll

The ReefMat 250 Replacement Fleece Roll is a genuine Red Sea non-woven polyester fleece mat designed for use with the ReefMat 250 automatic roller filter. It provides a fresh roll for continuous mechanical filtration, trapping detritus, uneaten food, and fine particulate waste to keep aquarium water clear and clean.

Key Features & Benefits:

• Continuous, automated filtration: As part of the ReefMat system, the fleece roll advances automatically (via the ReefMat’s smart drive unit) when water level rises — meaning clean filter media is always in use.

• Improves water quality: By removing fine waste from the water before it breaks down, the fleece reduces the buildup of nutrients, which supports a healthier tank overall.

• Easy to install: Rolls can be replaced quickly without removing the filter or shutting off pumps — no tools needed.

Ideal For:
Saltwater reef and FOWLR systems that use the ReefMat 250 roller filter — especially moderate-stocked aquariums (up to 65 gallons) where keeping water clarity and low nutrients is critical. 

Why Reefers Like It:
Because it automates one of the messiest aspects of sump maintenance (dirty filter socks), the ReefMat 250 Replacement Fleece Roll delivers significant convenience and helps maintain cleaner, more stable water. That translates into healthier corals, reduced algae issues, and less frequent sump cleaning — a big win for reef hobbyists.
