At 549 L, water alone weighs roughly 549 kg before the glass, cabinet, rock and substrate are added — Red Sea does not publish a total filled weight for this model, so on an upper floor or bearer-and-joist construction it's worth having the floor checked before it goes in.\u003c\/p\u003e\u003ch3\u003ePerformance\u003c\/h3\u003e\u003cp\u003eThe ReefRun G2 8000 DC return pump is rated across a 4,100–8,300 L\/h range with up to 5.3 m of head — the top of that range is a best-case, low-head figure, and actual delivered flow drops once it's working against the lift and plumbing resistance of the installed system. Red Sea publishes a PAR-at-depth chart for the ReefLED G2 170 fixture on its own site; we haven't reproduced exact figures here as we couldn't verify them against the live chart at time of writing — ask us if you'd like the current chart before you buy.\u003c\/p\u003e\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\u003cp\u003eSuited to a reefer wanting a wide, shallow display with lighting, flow, skimming and filtration matched and pre-plumbed, in a footprint shorter than a standard Reefer of similar volume. Not the right starting point for a first marine tank — there's no dosing, heating or RO\/DI provision, and set-up, cycling and ongoing dosing workload scale with system size.\u003c\/p\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cp\u003eThe ReefMat roller reduces mechanical filtration to periodic roll changes rather than weekly sock washing; skimmer cup emptying and gyre pump impeller cleaning remain routine tasks. Budget for ReefMat roll refills and skimmer neck cleaning as the main consumables.\u003c\/p\u003e\u003ch3\u003eSafety\u003c\/h3\u003e\u003cp\u003eAll included electrical equipment is mains-powered — run it through an RCD-protected circuit, and keep drip loops on every cable entering the cabinet.\u003c\/p\u003e\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\u003cp\u003eCovered by Red Sea's manufacturer warranty, which applies in addition to your consumer guarantee rights under Australian Consumer Law. This is an oversized item typically shipped assembled or part-assembled on a pallet — expect a two-person kerbside or room-of-choice delivery depending on access, and confirm stair or doorway clearance before ordering.\u003c\/p\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003ch4\u003eWhat's the difference between the standard Reefer-S 550 G2+ and the MAX?\u003c\/h4\u003e\u003cp\u003eThe standard Reefer-S 550 G2+ is the aquarium, cabinet, plumbed sump and ReefATO+ only. The MAX adds the lighting, return pump, gyre circulation, skimmer and filter roller already fitted — it's a running system rather than a tank you still need to equip.\u003c\/p\u003e\u003ch4\u003eDo I still need a heater?\u003c\/h4\u003e\u003cp\u003eYes. Heating isn't included in any Reefer-S package tier — size a heater to 549 L and your room's typical low ambient temperature.\u003c\/p\u003e\u003ch4\u003eWhat makes the Reefer-S different from a standard Reefer?\u003c\/h4\u003e\u003cp\u003eRed Sea builds the Reefer-S wider and deeper than the standard Reefer at a given volume — this 550 is 68 cm wide and 65 cm deep, rather than the narrower, taller footprint of an equivalent-volume standard Reefer.\u003c\/p\u003e\u003ch4\u003eIs the floor under this tank a concern?\u003c\/h4\u003e\u003cp\u003eAt 549 L it's worth checking, particularly on an upper floor — water alone weighs around 549 kg before cabinet, glass, rock and sand are added, and Red Sea doesn't publish a filled weight for this model.\u003c\/p\u003e","brand":"RedSea","offers":[{"title":"Default Title","offer_id":55242245013795,"sku":"AA3504","price":11700.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/Red_Sea_Reefer_G2_Max_S-550_Black.jpg?v=1782108775","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/red-sea-reefer-s-max-550-g2","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
