Red Sea Reefer G2+ 625 Complete System white - 625L

• Rimless, low-iron (ultra-clear) glass display aquarium with bevelled edges
• Matching marine-grade laminated cabinet with aluminium support structure
• Red Sea reef-spec in-cabinet sump, including a mechanical filtration compartment with micron filter/filter cups, an adjustable-height skimmer chamber and a bubble trap
• Central overflow box with surface skimmer weir and a silent emergency downflow with enlarged rectangular inlet
• Integrated auto top-off (ATO) reservoir chamber built into the sump
• Assembly-ready plumbing with bulkhead connectors in both metric and imperial (USA) sizes

• Return pump
• Protein skimmer
• Lighting (LED fixtures and mounting arms)
• Electronic ATO controller/dosing unit (the sump provides a reservoir chamber only; the powered top-up unit is a separate purchase)
• Heater, wavemaker/circulation pumps, media reactors and controllers
• Substrate, aquascaping rock and livestock

• 620 L total system volume across a 497 L display and a 123 L in-cabinet sump, giving real filtration and equipment capacity without eating into display water.
• Low-iron, rimless glass for an unbroken, distortion-free view into the display from any angle.
• 19 mm front and side panels with a 15 mm base built for the long-term load of a large-format reef tank.
• Silent emergency downflow with an enlarged rectangular inlet reduces the risk of a noisy or overwhelmed overflow if the return pump you fit runs hard.
• Central overflow with surface skimmer weir pulls surface film and debris into the sump before it settles in the display.
• Sump-based ATO reservoir gives you a dedicated top-up water chamber, ready for whichever auto top-off unit you choose to add.
• Dual-standard plumbing fittings (metric and imperial) simplify sourcing pumps, chillers and reactors from either market.
• Matching marine-grade cabinet conceals the sump and plumbing while supporting the footprint and weight of a 625 L-class system.

The Reefer G2+ range is the bare tank-cabinet-sump platform: it does not include lighting, a protein skimmer or a return pump, so you choose and fit that equipment yourself. Red Sea's Reefer MAX range, by contrast, is built as a plug-and-play system and comes with lighting, a DC return pump, a protein skimmer and Red Sea's ReefBeat-connected auto top-off in the box. If you want to add your own preferred brands of equipment (or already own them), the G2+ platform, as listed here, is the better fit. If you would rather everything arrive fitted and ready to run, look at the Reefer MAX 625 instead.

• Reefkeepers upgrading from a smaller system who already own (or are buying separately) a return pump, skimmer and lighting
• Buyers who want to specify their own equipment brands rather than a bundled package
• Larger reef or mixed-fish displays where 497 L of display volume and 123 L of sump capacity suit the stocking plan
• Installations where the floor structure has been checked for a large filled aquarium system

• First-time marine keepers wanting a single plug-and-play purchase – consider the Reefer MAX range instead
• Anyone expecting lighting, a skimmer or a return pump to be in the box
• Upper-floor or unconfirmed-floor installations without a builder or engineer sign-off for the load

Red Sea provides a 3-year standard warranty from the date of purchase, extending to 5 years on the glass aquarium and cabinet if you register the product with Red Sea within 90 days – Australia is listed as an eligible region for this extension. These manufacturer terms sit alongside, and do not replace, your rights under Australian Consumer Law. Given its size and weight, this item is an oversize system: expect palletised freight, likely two-person or trade delivery, or warehouse pickup, and confirm access (stairs, doorways, driveway) before delivery is arranged.

Does the Reefer G2+ 625 come with lighting, a skimmer or a return pump?

No. The G2+ 625 is supplied as the aquarium, cabinet, sump and plumbing only. Lighting, a protein skimmer and a return pump are not included and need to be purchased separately.

How much does the system weigh filled?

Red Sea does not publish an empty or filled weight for this model. As a guide, the 620 L of water alone weighs roughly 620 kg, before adding the tank, cabinet, sump, substrate and rock – for an installation this size we recommend confirming floor loading with a builder or engineer.

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

The G2+ is a bare tank, cabinet and sump platform with no lighting, skimmer or pump included. The Reefer MAX range is the equivalent tank and cabinet sold as a complete plug-and-play package with lighting, a DC return pump, a protein skimmer and a connected auto top-off system included.

Is the glass low-iron and rimless?

Yes. The display panels are low-iron (ultra-clear) glass with a rimless, bevelled-edge design – 19 mm on the front and sides and 15 mm on the base.

Does the sump include an auto top-off system?

The sump has a built-in ATO reservoir chamber, but the powered auto top-off controller itself (Red Sea's ReefATO+ or an equivalent) is not included and is purchased separately.

What is the total water volume compared with the display volume?

Total system water volume is 620 L, made up of a 497 L display and a 123 L sump. The "625" in the model name is Red Sea's nominal size designation for this tank.
