Red Sea does not publish a total filled weight for this model. A filled 900 comfortably exceeds a tonne on a domestic floor once rock and substrate are included, so have the floor structure checked — ideally by a builder or structural engineer — before installing, particularly upstairs or on a suspended timber floor.\u003c\/p\u003e\n\u003ch3\u003eSetting it up\u003c\/h3\u003e\n\u003cp\u003eThe 900 is plumbed and drilled at the factory, so assembly is largely mechanical: cabinet, aquarium, sump, then plumbing. You'll still need to choose and fit a return pump sized to your plumbing run and head height, a skimmer sized to the system's bioload, and lighting sized to the tank's 65 cm depth and 200 cm span. The sump's dimensions suit Red Sea's own REEFER-specific accessories, but skimmers, pumps and lights from other reef-reputable brands fit the same footprint.\u003c\/p\u003e\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSuitable for: experienced reef keepers building a large-format SPS, mixed or predominantly soft coral display, and anyone who wants to choose their own filtration and lighting rather than take a bundled set\u003c\/li\u003e\n\u003cli\u003eNot suitable for: a first marine tank, a room with limited floor loading, or anyone who wants everything running on day one — for that, the REEFER MAX 900 G2+ is the better starting point\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003cp\u003eThe sump's filtration compartment and skimmer chamber are designed for regular filter sock or media changes. The overflow's weir comb lifts out for cleaning. Check the ReefATO+ probe periodically for algae growth, which can cause false top-off readings.\u003c\/p\u003e\n\u003ch3\u003eSafety\u003c\/h3\u003e\n\u003cp\u003eThe ReefATO+ unit is mains-powered (240 V, AU plug) and includes a leak detector that cuts the top-off pump if it senses water outside the sump. Run it, and any pump or heater you add, through an RCD-protected circuit.
