Red Sea REEFER S-1000 G3 White Flagship Reef System

• Largest REEFER-S G3 format: The S-1000 gives reef keepers a 210 cm display for a major long-format reef installation.
• 264.2 gallon total volume: The 1000 L system provides serious stability, room for mature coral colonies, and flexibility for advanced filtration planning.
• White aluminum cabinet: The white cabinet visually lightens the large aquarium while retaining a rigid premium aluminum support structure.
• Split sump design: The main sump and extension section provide extensive room for filtration, refugium planning, frag space, equipment, and future upgrades.
• Base-system flexibility: Return pumps, lighting, skimmer, heater, wavemakers, dosing, and monitoring can be selected separately.
• Premium showpiece potential: The S-1000 White is suited to large homes, offices, showrooms, and dedicated reef spaces where the aquarium is intended to be a centerpiece.

210 cm Euro-Braced Ultra-Clear Display

• 795 litre display volume: The aquarium provides 209.9 gallons of main display space for long reef structures, coral colonies, and carefully selected fish.
• 210 x 68 x 65 cm dimensions: The long display allows multiple aquascape zones, broad swimming lanes, open channels, and large coral layouts.
• 19 mm ultra-clear glass: The front, sides, bottom, and back are listed with 19 mm glass.
• Euro-braced construction: The braced top reinforces the large display while keeping a clean professional aquarium profile.
• Low-iron viewing quality: Ultra-clear glass improves colour presentation and clarity across the large viewing panels.
• Bright furniture presentation: The white cabinet helps the large system feel cleaner and more architectural in modern spaces.

White Aluminum Cabinet and Control Panel

• Aluminum super-structure: The cabinet uses a rigid support frame designed for a long-span flagship reef aquarium.
• Replaceable white panels: The exterior panels provide a clean modern finish and remain part of a modular cabinet design.
• Hidden adjustable feet: Leveling feet support correct installation on suitable flooring.
• Slide-out control panel: The included panel helps organize controllers, power supplies, dosing equipment, and smart reef hardware.
• Large equipment area: The cabinet provides space for split sump equipment, dual return planning, controllers, dosing, and long-term upgrades.
• Modern showpiece look: The white finish softens the visual mass of the 210 cm aquarium and suits contemporary display spaces.

G3 Plumbing, ReefGate, and Dual Returns

• Hydrodynamic G3 plumbing: The flow system is designed for efficient movement through a large display and sump.
• Quiet downflow system: The enlarged rectangular inlet reduces turbulence and supports quieter operation.
• ReefGate precision valve: Fine drain adjustment helps stabilize sump water level and reduce drain noise.
• Surface-skimming overflow: The central overflow includes a removable surface skimmer for easier maintenance and water-surface clarity.
• Curved dual return nozzles: Dual returns distribute water across the long aquarium and support a dual-pump plan.
• Pre-assembled plumbing: Included pipework keeps installation more organized than a custom plumbing build from scratch.

Split Sump and ReefATO+ Automation

• 205 litre sump volume: The split sump provides extensive equipment and filtration space for a flagship reef build.
• Main plus extension sections: The extension sump can support refugium use, frag planning, extra filtration, or flexible equipment organization.
• ReefMat-ready mechanical stage: Micron socks and media cups are included, and the layout is designed for optional ReefMat 1200 installation.
• Integrated ReefATO+: ReefATO+ helps stabilize water level and salinity while adding temperature monitoring and leak detection.
• Advanced filtration planning: The sump can support skimming, reactors, dosing, monitoring probes, automatic filtration, and nutrient export systems.
• Built for long-term automation: The S-1000 provides the space and infrastructure needed for a highly organized Red Sea smart ecosystem build.
