Red Sea REEFER Peninsula S-950 G3 Black Flagship Room-Divider System

• Largest Peninsula G3 platform: The S-950 G3 expands the room-divider concept to a 200 cm display with serious visual presence.
• 250.1 gallon total system volume: The 947 L system volume supports greater stability, larger coral colonies, and more advanced filtration planning.
• Black aluminum cabinet: The black cabinet creates a bold architectural installation while the aluminum super-structure supports the long peninsula span.
• Split-sump design: The S-950 adds a main sump plus extension section for extra filtration capacity, refugium use, frag grow-out, or other equipment planning.
• Custom large-reef equipment freedom: Dual return pump planning, lighting, skimmer selection, flow, heating, dosing, and control equipment can be chosen separately.
• Premium Red Sea ecosystem path: The system is ready for optional ReefRun, ReefLED, ReefMat, ReefWave, ReefDose, REEFER skimmer, and ReefBeat-connected hardware.

200 cm Euro-Braced Ultra-Clear Peninsula Display

• 757 litre display volume: The main aquarium provides 199.9 gallons of display space for a mature reef, larger fish movement, coral zones, and showpiece aquascaping.
• 200 x 68 x 65 cm dimensions: The long 200 cm footprint gives reef keepers substantial room for multiple aquascape zones, open channels, islands, and layered coral placement.
• 19 mm glass construction: The S-950 G3 uses 19 mm front, side, bottom, and back glass for a premium large-format build.
• Euro-braced display: The reinforced top provides added support while preserving a clean professional profile.
• Ultra-clear viewing panels: Low-iron glass improves clarity across the long display and helps coral colours show cleanly through the thick panels.
• Large room-divider proportions: The three-sided viewing format makes this model a centerpiece aquarium for large homes, offices, lobbies, and display areas.

Black Aluminum Super-Structure Cabinet

• Rigid aluminum support: The cabinet uses Red Sea’s robust aluminum super-structure for a high-end long-span installation.
• Replaceable black panels: The black exterior panels create a finished furniture-style look while remaining part of the modular REEFER-S cabinet system.
• Hidden adjustable feet: Leveling feet help properly support the large system on suitable flooring.
• Slide-out control panel: Controllers, power supplies, dosing hardware, and smart reef equipment can be mounted and accessed more cleanly.
• Large equipment bay: The cabinet provides room for the split sump, ReefATO+, dual return planning, cables, controllers, and future upgrades.
• High-impact display finish: The black cabinet visually grounds the large aquarium and keeps attention on coral colour and reef structure.

G3 Water Management and Dual Side Returns

• Optimized long-run plumbing: Hydrodynamic piping supports efficient water movement across the 200 cm peninsula span.
• Quiet rectangular downflow: The low-turbulence drain inlet helps reduce noise when the system is tuned correctly.
• ReefGate precision valve: The drain can be adjusted in fine increments for stable, near-silent sump operation.
• Central overflow: The removable surface skimmer helps pull surface film and floating debris into the filtration path.
• Dual curved side return outlets: Side returns help distribute return water along the peninsula display and support better coverage across the long layout.
• Dual pump planning: The recommended return configuration uses 2 x ReefRun G2 12000 pumps, sold separately, for strong turnover across the large display.

Split Sump and ReefATO+ Stability

• 189.6 litre sump volume: The split sump gives extensive room for skimming, mechanical filtration, media, reactors, probes, dosing lines, and return equipment.
• Main plus extension sump: The extension section can be used for a larger refugium, frag grow-out, extra filtration, or other large-system planning needs.
• ReefMat-ready mechanical stage: Micron socks and media cups are included, and the system is designed for optional Red Sea ReefMat 1200 installation.
• Integrated ReefATO+: ReefATO+ helps stabilize water level and salinity while adding temperature monitoring and leak detection.
• Advanced filtration planning: The sump layout supports skimming, reactors, nutrient export, automatic mechanical filtration, dosing, monitoring, and power management.
• Designed for serious reef systems: The S-950 gives advanced aquarists the infrastructure needed for a large, organized, long-term reef build.

Setup and Installation Notes

• Plan the installation space: Confirm the room has adequate clearance for three-sided viewing, glass cleaning, cabinet service, sump access, and delivery placement.
• Assemble and level the cabinet: Build the black aluminum cabinet according to Red Sea’s instructions and confirm it is level before placing the aquarium.
• Plan the slide-out control panel: Organize controllers, power supplies, dosing hardware, and cables before final equipment installation.
• Install the split sump: Confirm the main sump, extension sump, overflow, ReefGate valve, returns, and ReefATO+ are correctly installed.
• Select equipment before filling: Choose return pumps, lighting, skimmer, heaters, wavemakers, optional ReefMat, and test kits before adding water.
• Freshwater leak test: Run the entire system with freshwater before saltwater setup to verify plumbing, sump level, and return flow.
• Tune the ReefGate slowly: Make small valve adjustments until the overflow and sump run quietly and consistently.
• Use RO/DI water: RO/DI water is recommended for saltwater mixing and top-off.
• Cycle before stocking: Establish biological filtration fully before adding fish or corals.
