Red Sea Reefer S-1000 G3 - Black Cabinet

Red Sea Reefer S-1000 G3 - Black Cabinet

The Red Sea Reefer S-1000 G3 - Black Cabinet is a flagship 1000 litre / 264.2 gallon reef-ready aquarium and cabinet system for aquarists who want the largest REEFER-S G3 display with a black aluminum super-structure cabinet and high-capacity split sump.

Built for serious large reef installations, the S-1000 G3 includes a 210 cm euro-braced 19 mm ultra-clear glass aquarium, reinforced black aluminum cabinet, replaceable panels, slide-out control panel, split REEF-SPEC sump with main and extension sections, ReefMat-ready mechanical stage, ReefGate precision drain valve, central overflow with removable surface skimmer, curved dual returns, pre-assembled plumbing, and integrated ReefATO+ smart top-off control. This is a base REEFER-S system, so the operating equipment package is selected separately.

Red Sea REEFER S-1000 G3 Black Flagship Reef System

• Largest REEFER-S G3 platform: The S-1000 G3 gives reef keepers a 210 cm display for a true flagship reef installation.
• 1000 litre total system volume: The 264.2 gallon volume provides exceptional stability and long-term planning capacity for a mature reef.
• Black aluminum cabinet: The black super-structure gives the large system a bold professional look while supporting the long span.
• Split sump capacity: The main plus extension sump design provides major filtration flexibility for large-system equipment planning.
• Custom equipment freedom: Return pumps, lighting, skimmer, heater, wavemakers, dosing, and automation are selected separately for the intended reef.
• Showpiece reef foundation: The S-1000 is suited to advanced mixed reefs, SPS-capable systems, large LPS displays, and high-end room-divider-style reef planning against a wall.

210 cm Ultra-Clear Euro-Braced Display

• 795 litre display volume: The main aquarium provides 209.9 gallons of display space for large aquascapes, coral colonies, open swimming lanes, and showpiece fish planning.
• 210 x 68 x 65 cm dimensions: The 82.7 inch length gives unmatched space in the REEFER-S G3 lineup for multiple coral zones and long reef structures.
• 19 mm glass construction: The front, sides, bottom, and back are listed with 19 mm ultra-clear glass.
• Euro-braced design: Bracing reinforces the large aquarium while preserving a premium professional profile.
• Ultra-clear viewing: Low-iron glass helps maintain clarity across the long display and reduces colour distortion through thick panels.
• Major room presence: The S-1000 is intended for large homes, offices, showrooms, and dedicated reef spaces where the aquarium is a centerpiece.

Black Aluminum Cabinet and Slide-Out Panel

• Heavy-duty aluminum structure: The cabinet uses Red Sea’s premium aluminum super-structure for a long-span large aquarium installation.
• Replaceable black panels: Exterior panels give the system a finished black furniture look while retaining modular serviceability.
• Hidden adjustable feet: Leveling feet support careful installation on suitable flooring.
• Slide-out control panel: The panel helps organize controllers, power supplies, dosing equipment, and smart devices for a cleaner build.
• Large equipment cabinet: The cabinet provides room for split sump equipment, dual return planning, control hardware, cable routing, and long-term upgrades.
• Professional black finish: The black cabinet visually anchors the long display and keeps the reef itself as the focal point.

G3 Large-System Flow and ReefGate Control

• Optimized circulation design: REEFER-S G3 plumbing is designed for stronger, more efficient water movement through the display and sump.
• Quiet rectangular downflow: The enlarged inlet reduces turbulence and helps lower drain noise when tuned correctly.
• ReefGate precision valve: The high-precision drain valve allows fine adjustment for stable, near-silent operation.
• Surface-skimming overflow: The central overflow includes a removable surface skimmer for easier water-surface maintenance.
• Curved dual returns: Dual outlets distribute return flow across the long 210 cm aquarium and support a dual-pump strategy.
• Pre-assembled plumbing: Factory-designed plumbing gives the large system a clean and predictable installation path.

Split REEF-SPEC Sump and ReefATO+

• 205 litre sump volume: The high-capacity split sump gives extensive space for skimming, return pumps, media, reactors, dosing, probes, and future upgrades.
• Main plus extension sump: The extension section can be used for a larger refugium, frag area, extra filtration, or flexible equipment planning.
• ReefMat 1200 ready: The mechanical filtration stage includes micron socks and media cups and is designed for optional ReefMat 1200 installation.
• Integrated ReefATO+: ReefATO+ helps stabilize salinity and water level while adding temperature monitoring and leak detection.
• Advanced filtration potential: The sump layout can support automatic filtration, oversized skimming, reactors, dosing containers, and control equipment.
• Designed for serious reef systems: The S-1000 gives advanced aquarists the space and infrastructure needed for a fully featured large reef.
