Red Sea ReefMat 500 Fleece Roller Filter

• Plug & Play installation with multiple sump setup options
• Easy fleece-mat replacement system
• Efficient, high-flow, skimmer friendly, 50 g/m2, non-woven polyester fleece-mat rolls
• Smart drive unit – connected to the ReefBeat ecosystem
• Solid-State internal and external water level sensors (no moving parts)
• Integrated media basket for additional chemical filtration
• Kink-resistant, corrugated inlet hose with a USA/Metric PVC connector

The ReefMat comes fully assembled, straight out of the box. Designed to hang on a sump wall to conserve space, but also including mounting legs, you can place the ReefMat anywhere you want in your sump that has the space available. Both the drive unit and inlet hose can be positioned on either side of the ReefMat making installation work for any sump set up.
The ReefMat 500 comes with one 28m fleece roll (Replacement rolls can be found HERE). Each roll should last roughly 5-8 weeks on a moderately stocked 80 gallon reef system; however, bare-bottom tanks will typically exhaust rolls at a faster rate. Additionally, usage rate may be significantly higher for the first few weeks after installing a ReefMat while your system adjusts to the new level of mechanical filtration.

ReefBeat App

• One interface for all of Red Sea’s smart devices.
• Easy set-up and operation.
• On-line monitoring and notifications.

ReefBeat gives you timely notifications when the fleece not only needs maintenance, but also if it should get stuck or torn. If any error occurs, the motor will simply not attempt to feed any more fleece until the issue is resolved. The end of Roll Monitor function lets you know the daily average use, and how many days you have left before the filter roll runs out so you can plan ahead.

Safety & Precautions

• Indoor use only. Use only the power supply that came with the unit — a supply rated for fewer watts than the appliance can overheat.
• Do not run the unit if the cord or plug is damaged, if it is malfunctioning, or if it has been dropped. Do not attempt a cord repair yourself; return it for service or discard it.
• Leave a drip loop in every cord — the low point of the cable must sit below the socket so water running down the cable drips off rather than reaching the outlet. If a plug or socket does get wet, do not unplug it: kill the circuit at the breaker first.
• Unplug before fitting or removing parts and before cleaning. Pull the plug, never the cord.
• Keep children away from the equipment, and do not touch moving parts while it is running.
• Do not install or store it where it will be exposed to weather or to temperatures below freezing.
• Seawater aquariums only. That is Red Sea’s own restriction on the ReefMat, not a preference.
• Rating: 5 to 45 °C, 15–85 % RH, 100–240 V 50/60 Hz, 1 A at 10 W maximum, 12 Vdc, wireless 2402–2480 MHz at 32.43 mW.
• The hose connector has a left-hand thread. Turning it the way instinct says will loosen it. Spread the liquid sealant on the first 2 cm / 0.8″ of the hose’s inner surface with the finger-cover provided, screw the connector in until tight, and wipe out the excess. The pipe can be used before the sealant dries.
• Onboard the unit to ReefBeat before installing the fleece mat, not after.
• There are two solid-state level sensors and both matter: one inside the chamber drives the mat, one outside catches a high sump level when the return pump is off. Do not leave the external one disconnected.
• The drive unit stops the motor on a blocked or torn mat and notifies ReefBeat rather than feeding more fleece into the fault. If it has stopped, find the tear before you restart it.
• Leave 15 cm / 6″ of side clearance for the media basket on an RM500, or you will not get it out to service it.
• Do not touch the take-up shaft or the roller while the motor is running.
