It suits saltwater and reef systems up to 250 L, mounts on the sump wall or stands free on its own legs, and reports roll life and dispensing history through the Red Sea ReefBeat app.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-advancing fleece roller\u003c\/strong\u003e — the unit only feeds new fleece forward when the mat has loaded up, so a roll isn't wasted advancing on a timer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated to 3,500 L\/h\u003c\/strong\u003e — sized for systems up to 250 L with headroom for a well-stocked reef's mechanical load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid-state level sensing\u003c\/strong\u003e — no float switch or moving sensor to foul or stick.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated media basket\u003c\/strong\u003e — room for chemical filtration media, such as carbon or GFO, alongside the mechanical fleece stage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKink-resistant inlet hose\u003c\/strong\u003e — 32 mm ID corrugated hose with a universal PVC connector, positionable to either side of the unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReefBeat app monitoring\u003c\/strong\u003e — end-of-roll alerts and dispensing logs over Wi-Fi, so roll changes happen on your schedule rather than as an emergency.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eRecommended system size\u003c\/th\u003e\n\u003ctd\u003eUp to 250 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum flow capacity\u003c\/th\u003e\n\u003ctd\u003e3,500 L\/h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUnit dimensions (L x W x H)\u003c\/th\u003e\n\u003ctd\u003e16 x 20 x 49 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFleece roll size\u003c\/th\u003e\n\u003ctd\u003e8 cm wide x 32 m long\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFleece material\u003c\/th\u003e\n\u003ctd\u003eNon-woven polyester, approx. 50 g\/m²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRoll life (moderately stocked reef)\u003c\/th\u003e\n\u003ctd\u003eRoughly 5–8 weeks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInlet hose\u003c\/th\u003e\n\u003ctd\u003e32 mm ID, kink-resistant, universal PVC connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower supply\u003c\/th\u003e\n\u003ctd\u003e100–240 V AC, 50\/60 Hz input; 12 V DC output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower draw\u003c\/th\u003e\n\u003ctd\u003e1 A, 10 W maximum (intermittent — draws power only while advancing fleece)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnectivity\u003c\/th\u003e\n\u003ctd\u003eWi-Fi, Red Sea ReefBeat app\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater type\u003c\/th\u003e\n\u003ctd\u003eSaltwater \/ reef only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eWhich ReefMat do I need?\u003c\/h3\u003e\u003cp\u003eRed Sea makes the ReefMat in three sizes.

Running a unit near the top of its flow rating shortens roll life, since more water is being polished through the same width of fleece.\u003c\/p\u003e\u003ch3\u003ePerformance\u003c\/h3\u003e\u003cp\u003e3,500 L\/h is Red Sea's maximum flow capacity for the unit, not a flow-with-media-loaded figure — Red Sea has not published a curve showing how flow changes as the fleece loads with waste. That's normal for a passive roller filter, but it means the number on the box is a ceiling rather than a running average. In practice, flow through a loading fleece pad falls gradually until the sensor calls for the next section, at which point it resets. If you want guaranteed turnover for a specific bioload, plumb the ReefMat as a polishing stage after your main return rather than as the sole flow path.\u003c\/p\u003e\u003ch3\u003eWhat's included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eReefMat 250 drive unit, head unit and solid-state level sensor\u003c\/li\u003e\n\u003cli\u003eIntegrated media basket\u003c\/li\u003e\n\u003cli\u003e32 mm kink-resistant inlet hose with universal PVC connector\u003c\/li\u003e\n\u003cli\u003eMounting legs \/ bumper kit\u003c\/li\u003e\n\u003cli\u003eOne 32 m fleece roll\u003c\/li\u003e\n\u003cli\u003ePower supply\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eA \u003ca href=\"\/products\/red-sea-reefmat-fleece-mat-250\"\u003ereplacement fleece roll\u003c\/a\u003e and a \u003ca href=\"\/products\/red-sea-reefmat-nano-250-500-1200-power-supply\"\u003espare power supply\u003c\/a\u003e are both sold separately for ongoing running and as backup.\u003c\/p\u003e\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\u003cp\u003eSuited to marine and reef systems up to 250 L wanting continuous mechanical filtration without sock changes — nano and small-to-mid reef tanks with a compatible sump. Not suitable for freshwater use, and not sized correctly for systems over 250 L, where the fleece will load and need changing more often than the roll length comfortably allows; step up to the ReefMat 500 instead.\u003c\/p\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cp\u003eRoutine care is a fleece roll change every 5–8 weeks on a moderately stocked reef — faster on a bare-bottom, heavily-fed system, slower on a lightly stocked one. Wipe the drive rollers and level sensor free of salt creep at each roll change, and rinse the media basket if it's carrying chemical media. The ReefBeat app's end-of-roll monitor gives advance warning based on your system's actual usage pattern, so you can order the next roll before the current one runs out.\u003c\/p\u003e\u003ch3\u003eSafety\u003c\/h3\u003e\u003cp\u003eRun the included power supply through an RCD-protected outlet and keep a drip loop in the cable before it reaches the socket.

Bare-bottom or heavily-fed tanks will load the fleece faster; the ReefBeat app tracks your actual usage and gives advance notice before a roll runs out.\u003c\/p\u003e\u003ch4\u003eCan I run the ReefMat 250 without the app?\u003c\/h4\u003e\u003cp\u003eYes — it advances the fleece automatically based on its own level sensor regardless of a Wi-Fi connection. The app adds remote monitoring and end-of-roll alerts rather than being required for basic operation.\u003c\/p\u003e\u003ch4\u003eDoes it replace my main filter?\u003c\/h4\u003e\u003cp\u003eIt replaces the mechanical stage — filter socks, sponges or pad media — with continuous fleece filtration. Biological filtration (live rock, sump media) and any chemical filtration you run are separate and still needed.\u003c\/p\u003e\u003ch4\u003eWill this fit a system bigger than 250 L?\u003c\/h4\u003e\u003cp\u003eIt's rated to 250 L total system volume. Running it on a larger system means more flow through a narrower fleece width than it's sized for, shortening roll life — step up to the ReefMat 500 or 1200 for larger volumes.\u003c\/p\u003e\u003ch4\u003eIs this for freshwater or saltwater?\u003c\/h4\u003e\u003cp\u003eSaltwater and reef systems only.\u003c\/p\u003e","brand":"RedSea","offers":[{"title":"Default Title","offer_id":54774162063651,"sku":"RED852","price":645.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/red-sea-reefmat-filter-250-46119442579747.webp?v=1790239295","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/red-sea-reefmat-filter-250","provider":"Nicks AOT","version":"1.0","type":"link"}
