The Red Sea ReefMat is a game-changing automatic filter roller that provides high-performance mechanical filtration for reef tanks. It removes particulate waste before it can decompose into harmful nitrates and phosphates—making it a crucial tool for keeping nutrient levels low and water clarity high. Whether you’re upgrading your reef system or building a new one, this guide will walk you through everything you need to know to properly install, run, and maintain your Red Sea ReefMat.
What Is the Red Sea ReefMat?
The ReefMat is an automatic fleece filter system that uses a fine roll of filtering fabric to physically trap detritus, uneaten food, and organic waste as water flows through your sump. Unlike traditional filter socks that need to be manually cleaned, the ReefMat advances the fleece roll automatically, ensuring a clean section is always in place.
Key features include:
-
Smart roll advancement via sensors
-
Wi-Fi control through the Red Sea ReefBeat app
-
Drop-in installation for Red Sea REEFER and compatible tanks
-
Minimal maintenance with plug-and-play design
It’s ideal for reef keepers aiming for ultra-low nutrient systems (ULNS) or simply looking to reduce sump maintenance.
How to Set Up the Red Sea ReefMat
1. Unpack and Inspect
Open the box and confirm all parts are present, including:
-
ReefMat body
-
Roll holder and motor
-
Fleece roll
-
Power supply
-
Mounting accessories
Inspect for shipping damage before proceeding.
2. Install the ReefMat in Your Sump
Position the ReefMat in the designated filter section of your sump. Ensure the water flows directly into the intake chamber for optimal waste capture. The unit must be fully submerged up to the water line indicator.
Make sure there’s room for the fleece roll to advance without obstruction.
3. Load the Fleece Roll
Thread the fleece roll into the unit:
-
Place the new roll onto the top holder
-
Feed the fleece down through the inlet guide
-
Wrap it around the roller drum and guide it under the tension bar
-
Pull it through to the waste roll spool
Use the manual advance button to tighten the fleece until snug.
4. Connect the Power and ReefBeat App
Plug in the ReefMat and download the Red Sea ReefBeat app. Follow the app instructions to:
-
Connect the ReefMat to Wi-Fi
-
Calibrate fleece usage sensors
-
Set up roll advancement preferences
-
Enable push notifications
The app lets you monitor roll usage and alerts you when the roll is nearly finished or if there’s a jam.
How to Maintain the ReefMat
Although mostly hands-free, occasional maintenance ensures optimal performance:
-
Replace the fleece roll when depleted. Roll lifespan varies by tank size and bio-load.
-
Clean the sensors and intake screen weekly to avoid misreadings or blockages.
-
Inspect the waste roll to prevent buildup from restricting movement.
-
Wipe down the motor and electronics monthly using a dry cloth.
Pro tip: Keep a spare fleece roll on hand to avoid downtime.
Tips for Optimizing Performance
-
Use in conjunction with a Red Sea REEFER™ skimmer and phosphate media for best nutrient control.
-
Position in high-flow sections to capture maximum debris.
-
Avoid dosing trace elements or food near the ReefMat intake to prevent premature roll usage.
-
Combine with ReefBeat scheduling to monitor roll advancement trends.
Conclusion
The Red Sea ReefMat is more than a time-saving device—it’s a key component in maintaining clear water, low nutrients, and coral health in your reef system. With smart automation and thoughtful engineering, it takes the hassle out of mechanical filtration while improving tank stability and aesthetics.
