• White cabinet finish — reflects more light back into an open-plan room than the black cabinet, and shows dust less on a light-coloured floor; the tank, sump and equipment inside are identical to the black version.
• 850 L total system volume across a 680 L display and a 170 L sump — enough sump volume to run a refugium section alongside mechanical filtration and skimming.
• 19 mm ultra-clear glass, rimless — beveled edge, no full top rim, for a cleaner sightline into the display.
• Pre-fitted, glue-free plumbing — quick-connect bulkhead fittings with both metric and US-standard adapters.
• ReefATO+ standard — Red Sea's combined auto top-off, temperature monitor and leak detector, added onto this tank as part of the G2+ revision.
• White marine-spec cabinet — plywood construction with an internal aluminium support frame and adjustable levelling feet.

• REEFER-S 850 G2+ display aquarium with central overflow box, removable weir comb and emergency overflow
• Matching white cabinet with internal aluminium support frame and levelling feet
• REEF-SPEC sump with pre-fitted mechanical filtration compartment, skimmer chamber and refugium-capable extension
• Assembly-ready plumbing with quick-connect bulkhead fittings (metric and US adapters)
• ReefATO+ auto top-off unit with temperature monitor and leak detector

• Return pump — choose and buy separately to suit your plumbing run and head height
• Protein skimmer — not fitted on this base tier; step up to Deluxe or MAX if you want one included
• Lighting — no fixture or arms fitted; browse our aquarium lighting range separately
• Heater and any temperature controller
• Chiller
• Dosing pump system
• ReefMat automatic filter roller
• RO/DI unit and saltwater mix — the tank ships dry
• Live rock, sand, aquascape and livestock

"Complete System" in the product title refers to the tank, cabinet, sump and plumbing arriving as one package — not to a complete equipment stack. If you want lighting, flow and skimming already fitted, ask us whether the Deluxe or MAX configuration of this model is available before comparing prices elsewhere.

Red Sea hasn't published an empty or filled weight for this model. As a guide, water alone accounts for around 850 kg at full volume, before cabinet, glass, rock and sand. Have the floor checked before placing it anywhere other than a slab or a reinforced ground floor.

A fit for a reefer with a clear equipment plan already in mind — your own choice of return pump, skimmer and lighting brand — rather than someone who wants a single unbox-and-plumb purchase. If you'd rather everything arrived fitted, ask us about the MAX configuration of this model.

Filtration in the sump runs on micron filter bags and cups rather than an automatic roller, so budget for manual bag changes unless you add a ReefMat separately. Keep the ReefATO+ reservoir topped up with RO/DI water and its sensor clean.

Any mains-powered equipment in the cabinet, including ReefATO+, should run on an RCD-protected circuit with a drip loop on every cable entering the cabinet. Confirm quick-connect plumbing fittings are seated and hand-tightened, never with tools, before you fill the tank.

Covered by Red Sea's manufacturer warranty: 3 years standard, extendable to 5 years at no extra cost by registering the tank with Red Sea online, in addition to your consumer guarantee rights under Australian Consumer Law. This is an oversized, heavy item; expect a two-person delivery and confirm doorway and stair clearance before ordering.

Does this include a return pump, skimmer or lights?

No — this base configuration is the tank, cabinet, sump, plumbing and ReefATO+ auto top-off only.

What's the difference between this and the MAX version?

The MAX configuration adds a factory-matched return pump, skimmer and lighting, fitted and plumbed. This base listing is the platform only, for you to equip as you choose.

Does the cabinet come pre-built?

No — the cabinet ships flat-packed with its own assembly manual. The plumbing itself is pre-fitted with quick-connect fittings, so it doesn't need gluing.

How much does it weigh filled?

Red Sea hasn't published a filled weight for this model. Water alone runs to roughly 850 kg at full volume — have the floor checked before placing it anywhere other than a slab or reinforced ground floor.

Can I upgrade to Red Sea's own equipment later?

Yes — the tank and cabinet are designed around Red Sea's ReefLED, ReefWave and ReefRun range, so you can add them at any point rather than only at initial purchase.
