Allow clearance behind the cabinet for the ReefBeat control panel and cabling, and above the tank for the ReefLED mounting arms to sit clear of the water surface — roughly 20–25 cm above the rim is typical for this arm style, though we'd confirm against the arms in the box before fixing a shelf or hood above it.\u003c\/p\u003e\n\u003ch4\u003eHow much does it weigh filled, and will my floor take it?\u003c\/h4\u003e\n\u003cp\u003eRed Sea states the filled system at 690 kg. Spread evenly over the 120 x 60 cm (0.72 m²) cabinet footprint, that works out to roughly 960 kg\/m² — but real-world loading isn't even, and concentrates at the cabinet's feet or base rails rather than across the whole footprint. For a tank over 200 L on a suspended timber floor (as opposed to a slab), we'd suggest checking span and load rating with a builder before installation, particularly in an older Queenslander. This figure is our own calculation from the manufacturer's filled weight, not a Red Sea floor-loading rating — Red Sea does not publish one for this model.\u003c\/p\u003e\n\u003ch3\u003eRunning costs and noise\u003c\/h3\u003e\n\u003cp\u003eThe return pump, two lights, two ReefWave pumps and the skimmer's air draw are all DC units, which keeps running noise low relative to older AC-driven REEFER generations — Red Sea doesn't publish a dB figure for the assembled system, so we haven't invented one. We don't yet have a verified annual kWh figure for the combined system and won't publish an estimate we can't source; ask in store and we'll work through it with you against your local tariff.\u003c\/p\u003e\n\u003ch3\u003eSuitable for \/ not suitable for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for:\u003c\/strong\u003e mixed reef and FOWLR marine setups, softies-to-SPS lighting range via the ReefLED spectrum control, a first \"everything in one box\" reef build or an upgrade from a smaller REEFER.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e freshwater use as supplied — the included skimmer and DC return pump are marine-specific; species needing still water, since the gyre pumps and return flow together move a substantial volume; anyone expecting a heater or doser in the box.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003cp\u003eThe ReefMat filter roller needs a fresh roll of media on a schedule rather than a daily rinse — check the roll level through the sump viewing panel and keep spares on hand rather than waiting until it runs out. The skimmer cup should be emptied and rinsed regularly during bioload changes or new-tank cycling, when skimmate production is heaviest.\u003c\/p\u003e\n\u003ch3\u003eSafety\u003c\/h3\u003e\n\u003cp\u003eThis is a mains-powered marine system — the return pump, lights, ReefWave pumps, skimmer and ATO all run from GPO power. Use a dedicated RCD-protected circuit for the fish room or cabinet power board, keep power leads looped (\"drip-looped\") below socket height, and fit a divider or shelf between electrical connections and any water top-up point. A heater is not included; if you fit one, match it to a thermostat suited to the water volume and never run a heater without one.\u003c\/p\u003e\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eRed Sea backs this system with the manufacturer's standard warranty, in addition to your rights under the Australian Consumer Law — ask in store for the current term, as we don't want to quote a figure here that a policy update could make wrong.
