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

• Largest Peninsula G3 display: The S-950 G3 uses a 200 cm peninsula format for a dramatic three-sided reef installation.
• 947 litre total system volume: The 250.1 gallon system volume supports large coral colonies, mature aquascapes, advanced filtration, and more stable water conditions.
• White aluminum cabinet finish: The white cabinet helps visually lighten the large aquarium while maintaining the strength of the REEFER-S aluminum super-structure.
• Split-sump flexibility: The main plus extension sump design gives extra room for refugium planning, frag grow-out, additional filtration, or equipment organization.
• Custom equipment freedom: Return pumps, reef lighting, skimmer, heaters, wavemakers, dosing, monitoring, and optional filtration hardware can be selected separately.
• Premium room-divider impact: This model is suited to large homes, offices, lobbies, showrooms, and dedicated aquarium spaces where the tank is a centerpiece.

200 cm Ultra-Clear Euro-Braced Peninsula Display

• 757 litre display volume: The main display provides 199.9 gallons of aquarium space for a large reef structure, broad coral zones, open sand, and selected reef fish.
• 200 x 68 x 65 cm dimensions: The long and deep footprint creates a major aquascaping canvas with strong three-sided visibility.
• 19 mm glass specification: The front, side, bottom, and back panels are listed at 19 mm for a substantial large-system build.
• Euro-braced construction: The reinforced top frame adds structural support while keeping the display clean and professional looking.
• Low-iron clarity: Ultra-clear glass reduces tint and improves the visual impact of coral colour and reef lighting.
• Designed for multi-angle aquascaping: Rockwork, coral placement, and equipment placement should be planned so the reef looks finished from both long sides and the end panel.

White Aluminum Cabinet and Control Panel

• Aluminum super-structure: The cabinet uses a rigid aluminum support frame for extra fortification across the 200 cm peninsula span.
• Replaceable white panels: The exterior panels give the system a clean modern appearance while remaining part of Red Sea’s modular cabinet design.
• Hidden adjustable feet: Leveling feet help support correct installation on suitable flooring.
• Slide-out control panel: The control panel gives a dedicated serviceable location for controllers, power supplies, dosing equipment, and smart reef devices.
• Large equipment compartment: The cabinet accommodates the split sump, ReefATO+, power management, dual return planning, and long-term upgrades.
• Bright architectural finish: The white cabinet softens the visual weight of the large aquarium and suits modern interiors and showroom spaces.

G3 Plumbing with ReefGate and Dual Side Returns

• Hydrodynamically optimized piping: The G3 flow path is designed for efficient movement through the long room-divider layout.
• Quiet rectangular downflow: The enlarged drain inlet reduces turbulence and helps the system run quietly when tuned.
• ReefGate precision valve: The drain line can be adjusted finely for stable water height and near-silent operation.
• Central overflow: The removable surface skimmer helps pull surface film and debris into the filtration path.
• Dual curved side returns: Side returns help spread return flow along the peninsula span and across the open reef structure.
• Dual return pump planning: The recommended configuration uses 2 x ReefRun G2 12000 pumps, sold separately, to support the large display.

Split REEF-SPEC Sump and ReefATO+

• 189.6 litre sump volume: The split sump gives major equipment capacity for skimmers, return pumps, media, probes, reactors, dosing lines, and service access.
• Main plus extension sump: The extension section can be used as a larger refugium, frag area, added filtration zone, or flexible equipment space.
• ReefMat-ready mechanical chamber: The system includes micron socks and media cups and 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 potential: The sump layout can support automatic mechanical filtration, skimming, reactors, nutrient export, dosing, and monitoring equipment.
• Built for long-term reef growth: The S-950 gives advanced aquarists enough space and infrastructure to build a highly organized large reef system.

Setup and Installation Notes

• Plan the room-divider footprint: Confirm access for three-sided viewing, glass cleaning, sump maintenance, cabinet service, and freight delivery before ordering.
• Assemble and level the cabinet: Build the white aluminum cabinet according to Red Sea’s instructions and confirm it is level before placing the aquarium.
• Use the slide-out control panel: Plan controller, power supply, dosing, and cable management before the cabinet is filled with equipment.
• Install the split sump carefully: Confirm the main sump, extension sump, overflow, ReefGate valve, return plumbing, 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 final saltwater setup.
• Tune the ReefGate gradually: Adjust the valve in small increments until the overflow and sump run quietly and consistently.
• Use RO/DI water: RO/DI water is recommended for saltwater mixing and evaporation top-off.
• Cycle before stocking: Establish biological filtration fully before adding livestock.
