• 750 L total system volume — 600 L display over a 150 L sump, so bioload and dosing capacity scale with the display rather than being squeezed by an undersized sump.
• Triple ReefLED G2 170 lighting — full-tank coral-growth spectrum with mounting arms included, run and dimmed from the Red Sea ReefBeat app rather than a separate driver.
• Twin ReefWave 45 gyre pumps — wide, low-turbulence flow for coral placement across a 180 cm display, controlled independently of the return pump.
• ReefRun G2 DC return pump — variable-speed, app-controlled, feeding the plumbed overflow and drainpipe with a silencing valve.
• REEFER DC Skimmer 900 and ReefMat 1200 — mechanical and protein export handled from day one, with the filter roller cutting weekly filter-sock changes to occasional roll changes.
• ReefATO+ auto top-off — holds salinity steady between water changes without a separate reservoir pump.
• Pre-glued sump plumbing — assembly-ready piping, no solvent welding on setup day.

• REEFER 750 G2+ display aquarium and matching cabinet
• Sump with pre-glued plumbing and slide-out control panel
• 3 x ReefLED G2 170 lighting with mounting arms
• 2 x ReefWave 45 gyre circulation pumps
• ReefRun G2 DC return pump and controller
• REEFER DC Skimmer 900
• ReefMat 1200 automatic filter roller
• ReefATO+ auto top-off unit
• Utility basket

• Heater and any temperature controller — sized separately to your room's ambient temperature
• Chiller, for climates or rooms where ambient heat pushes the tank above a safe reef temperature
• Dosing pump system, for two-part or trace element dosing beyond what water changes provide
• RO/DI unit and saltwater mix — the tank ships dry
• Live rock, sand or aquascape, and livestock
• Test kits and a phone or Wi-Fi network for the ReefBeat app

This is a MAX package, not a bare Reefer: the lighting, return pump, gyre flow and skimmer are already fitted. A standard (non-MAX) Reefer 750 G2+ ships as the aquarium, cabinet and plumbed sump only, with none of the above equipment — the two are different purchases at different price points, and it's worth checking which listing you're looking at before comparing prices elsewhere.

Allow the full 148 cm system height plus ceiling clearance for lid removal and light servicing, and at least 10 cm behind the cabinet for return plumbing, the ATO reservoir line and cabling. At 750 L total volume this is a floor-loading item: water alone weighs roughly 750 kg before the glass, cabinet, rock and substrate are added, so the true filled weight is meaningfully higher again. Red Sea does not publish a filled weight figure for this model, so if it's going anywhere other than a slab or a reinforced ground floor, get the floor checked by a builder or engineer before it goes in — this is exactly the kind of large-system weight that goes unstated and shouldn't be guessed at.

The ReefWave 45 pumps are rated at up to 3,960 GPH (roughly 15,000 L/h) combined at the pump face, in gyre mode across the display width — actual in-tank flow depends on rock placement and pump aim, as with any powerhead. Red Sea has not published a head-loss curve for the ReefRun G2 DC return pump used in this package, so the flow figure printed on Red Sea's own marketing is a best-case, zero-head number; expect noticeably less once it's pushing water up through the drain plumbing and skimmer. Ask us for the manufacturer's curve sheet if you want to plan dosing or turnover around the delivered figure rather than the headline one.

Suited to established reefers running SPS-dominant or mixed reef displays who want lighting, flow, skimming and mechanical filtration matched and pre-plumbed rather than assembled component by component. Not the right starting point for a first marine tank — there's no dosing, heating or RO/DI provision, and a 750 L system carries a proportionally larger cycling, dosing and top-up workload than a nano or standard-size reef.

The 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.

All included electrical equipment is mains-powered — run it through an RCD-protected circuit, and keep drip loops on every cable entering the cabinet. The sump's drain plumbing includes a valve for silent operation; check it after any plumbing disturbance, as an incorrectly set valve can cause overflow noise or, in a worst case, a sump overflow.

Covered by Red Sea's manufacturer warranty, which applies in addition to your consumer guarantee rights under Australian Consumer Law. This is an oversized, heavy item 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.

What's the difference between the standard Reefer 750 G2+ and the MAX?

The standard Reefer 750 G2+ is the aquarium, cabinet and plumbed sump only. The MAX adds the lighting, return pump, gyre circulation, skimmer, filter roller and auto top-off already fitted — it's a complete running system rather than a tank you still need to equip.

Do I still need a heater?

Yes. Heating isn't included in any Reefer package tier — size a heater or heater pair to 750 L and your room's typical low ambient temperature.

Can the lighting and pumps run without Wi-Fi?

They'll run on their last set programme without a network connection, but scheduling, ramping and remote monitoring through ReefBeat need a Wi-Fi connection.

Is the floor under this tank a concern?

At 750 L total volume, yes — it's worth checking with a builder or engineer, particularly on an upper floor or bearer-and-joist construction. Red Sea doesn't publish a filled weight for this model; the water alone is around 750 kg before cabinet, glass, rock and sand are added.

Does this include a dosing system?

No. A dosing pump system for two-part or trace elements is sold separately and isn't part of any Reefer 750 package tier.
