Red Sea Reefer Peninsula S-950 G3+ - White Cabinet

Red Sea Reefer Peninsula S-950 G3+ - White Cabinet

The Red Sea Reefer Peninsula S-950 G3+ - White Cabinet combines a 757 litre (200 US gallon) eurobraced ultra-clear glass aquarium with a 189.6 litre (50.1 gallon) combined split-sump filtration system and a premium white cabinet built around a marine-spec anodized aluminum superstructure. With a total published system volume of 947 litres (250.2 US gallons), this large peninsula aquarium provides an impressive three-sided reef display for open-concept homes, offices, lobbies, and other spaces where the aquarium can become a central feature.

The Peninsula S-950 G3+ measures 200 cm (78.7 inches) long, 68 cm (26.8 inches) wide, and 65 cm (25.6 inches) high, providing substantial room for extended rockwork, multiple coral zones, and open swimming areas. Its 19 mm ultra-clear glass, jet-black eurobracing, dual curved 25 mm side-facing returns, and precision ReefGate valve provide the structural and water-management foundation. The white aluminum-superstructure cabinet includes replaceable exterior panels and a slide-out control panel, while the multipurpose extension sump offers additional filtration or independent reservoir options. ReefControl Pro and the ReefControl ATO Module are included for connected freshwater top-off and temperature monitoring.

Red Sea Reefer Peninsula S-950 G3+ White Three-Sided Display

• 200 cm (78.7 inch) aquarium length: The extended display provides room for substantial reef formations, separate coral colonies, open sand areas, and swimming channels across a large marine aquarium.
• Three-sided room-divider viewing: The aquarium can be enjoyed through both long glass panels and the exposed end, making it suitable for prominent installations where a conventional aquarium back panel would interrupt the view.
• 68 cm (26.8 inch) aquascaping width: The generous footprint supports central rock islands, layered reef structures, caves, and open channels that remain visible from multiple directions.
• 65 cm (25.6 inch) display height: The vertical dimension provides room for multi-level aquascapes and coral placement at different depths.
• 757 litre (200 gallon) main display: The substantial aquarium provides space for carefully planned mature coral colonies and appropriately selected marine livestock, with filtration equipment housed below.
• 19 mm (0.75 inch) ultra-clear front glass: Low-iron viewing panels reduce unwanted glass tint across the extensive display.
• Jet-black eurobracing: Perimeter reinforcement and high-quality euro-silicone provide structural strength while creating a distinctive upper frame around the aquarium.
• Premium white cabinet: The light exterior finish provides a contrasting furniture-style base beneath the glass display while retaining Red Sea's robust aluminum supporting structure.

Marine-Spec Aluminum Cabinet and Equipment Organization

The Peninsula S-950 G3+ cabinet uses Red Sea's premium anodized aluminum superstructure with replaceable white exterior panels. The extended cabinet accommodates the main and extension sump sections, while the slide-out control panel provides a dedicated location for compatible monitoring equipment and other reef electronics.

• Rigid anodized aluminum support frame: The superstructure provides structural reinforcement across the large peninsula installation.
• Replaceable white exterior panels: The modular cabinet offers a bright finished appearance while allowing exterior components to be serviced separately from the aluminum frame.
• Hidden heavy-duty leveling feet: Concealed adjustments allow the cabinet to be accurately leveled before positioning and filling the aquarium.
• Slide-out control panel: The accessible mounting surface helps organize compatible ReefControl equipment, dosing pumps, power supplies, and associated wiring.
• Split-sump accommodation: The cabinet houses the professional main filtration sump and its multipurpose extension, providing flexibility for equipment and reservoir planning.
• Three-sided viewing clearance: The aquarium should be positioned with space to clean both long panels and the exposed end, rather than placing a viewing face directly against a wall.
• Maintenance-oriented equipment layout: Position pumps, controllers, filtration equipment, and tubing so that servicing can be completed without unnecessarily dismantling the installation.

Flexible Split-Sump Filtration and Multipurpose Extension

The S-950 G3+ is the only Peninsula G3+ model with Red Sea's multipurpose split-sump arrangement. Its professional main REEF-SPEC sump contains the core filtration and return equipment, while a separate glass extension can be connected for additional filtration or operated independently for another aquarium-support application.

• 189.6 litre (50.1 gallon) published combined sump capacity: The main and extension sumps provide substantial filtration volume when both are connected to the circulating aquarium system.
• Professional main filtration sump: The main sump houses mechanical filtration, the adjustable protein skimmer chamber, and return circulation equipment.
• Additional connected filtration: The glass extension can provide extra filtration volume, a larger refugium, or room for other compatible water-treatment equipment.
• Independent freshwater reservoir: When disconnected from the main filtration system, the extension can hold RO/DI freshwater for automatic top-off.
• Prepared saltwater storage: The extension can alternatively operate as an independent reservoir for saltwater used during aquarium maintenance and water changes.
• Dedicated coral frag tank: With suitable independent lighting, circulation, and temperature management, the extension can be configured for coral propagation.
• Circulating volume clarification: The manufacturer's 947 litre system rating incorporates the combined sump capacity. Water in an independently operated extension reservoir or frag tank does not contribute to the display's circulating system volume.
• Optional main-sump refugium divider: A compatible partition provides an additional option for establishing a refugium within the primary filtration sump.
• Configuration before installation: Determine how the extension will be used before choosing return plumbing, filtration accessories, automatic water-change equipment, and reservoir connections.

ReefMat-Ready Mechanical Filtration and Protein Skimmer Options

The professional REEF-SPEC main sump includes removable mechanical filtration and an adjustable-height skimmer chamber. The included filter bags and media cups provide conventional particle collection, while the mechanical section can accommodate compatible automatic roller filtration when the aquarist prefers an alternative to manually cleaning filters.

• Two 225-micron mechanical filter bags: The included fine-mesh filters collect suspended particles and debris entering the sump and can be removed for routine cleaning.
• Two filter media cups: The mechanical filtration section also includes two cups for alternative filtration arrangements.
• Removable ReefMat-ready compartment: The mechanical filtration assembly can be replaced with compatible automatic fleece filtration without rebuilding the standard downflow plumbing.
• Optional ReefMat 1200: Red Sea specifies the ReefMat 1200 for the equivalent REEFER MAX Peninsula S-950 G3+ package, providing an identified automated filtration upgrade.
• Adjustable skimmer chamber: Red Sea lists an adjustable operating water depth of 17-27 cm (6.7-10.6 inches) for the Peninsula G3+ filtration system, allowing compatible protein skimmers to operate at their required depth.
• Refugium-ready main sump: An optional divider can establish a separate area for additional biological filtration and nutrient-management equipment.
• Expanded refugium option: The glass extension can be used for additional connected refugium space when that arrangement is preferred over independent freshwater or saltwater storage.
• Equipment fitment: Confirm skimmer dimensions, return pump placement, mechanical filtration clearance, and available access before installing the complete system.

ReefGate Precision Drainage and Dual Side-Facing Returns

The Peninsula S-950 G3+ uses hydrodynamically optimized piping designed to move filtered water along its large room-divider display. Two curved side-facing return outlets direct water toward the far end of the aquarium, while the enlarged downflow and high-precision ReefGate valve regulate drainage to the sump.

• Two curved 25 mm (approximately 1 inch) return outlets: The side-mounted connections distribute filtered water along the aquarium and support compatible single- or dual-pump configurations.
• ReefGate precision valve: Small downflow adjustments help balance the overflow water level against the selected return pump arrangement for quiet, consistent operation.
• Enlarged rectangular drain inlet: The redesigned downflow entrance helps reduce turbulence as water travels into the filtration plumbing.
• Removable surface-skimming combs: Accessible overflow sections can be removed for cleaning to maintain unrestricted collection of water from the aquarium surface.
• Hydrodynamically optimized water path: Red Sea's peninsula return plumbing is designed to distribute water along the extended display while reducing unnecessary flow restrictions.
• Flexible pump arrangement: The dual outlets allow different compatible return-pump configurations depending on the selected equipment and plumbing design.
• Correct model-specific fittings: Red Sea's G3+ technical specifications list dual 25 mm return connections for the Peninsula S-950. Custom fittings should be matched to this model rather than to other large REEFER-S systems.
• Additional circulation equipment: Dedicated wavemakers should be positioned to move water around central rock formations and coral colonies without unnecessarily obstructing the three-sided view.

Integrated ReefControl Pro and Smart Automatic Top-Off

The S-950 G3+ includes ReefControl Pro and the ReefControl ATO Module as standard hardware. This provides digital automatic freshwater replenishment and temperature monitoring, with additional connections available for compatible ReefSense probes and controlled equipment.

• ReefControl Pro Controller: Supports up to seven compatible ReefSense digital probes or sensors and two 12V DC devices for additional monitoring and control.
• Automatic freshwater replacement: The ATO Module monitors sump water level and operates its dedicated DC pump to replace freshwater lost through evaporation.
• Integrated temperature monitoring: The digital ATO level sensor also measures aquarium temperature, allowing supported readings and notifications through ReefControl.
• ReefBeat connected platform: Compatible monitoring devices and aquarium equipment can be configured and monitored through Red Sea's ReefBeat ecosystem.
• Included ATO installation hardware: The module includes its digital sensor, mounting components, DC top-off pump, silicone tubing, tube holder, and siphon breaker.
• Optional ReefSense probes: Compatible pH, salinity, ORP, and other digital monitoring probes can be selected separately as required.
• Additional equipment management: Optional ReefControl Power hardware can provide supported AC device control alongside the Pro controller's existing connections.
• Standard versus MAX package: ReefControl Pro and the ATO Module are included, but additional water-parameter probes and the complete MAX lighting, skimming, return pump, wavemaker, and roller-filter equipment are not.

Equipment Selection for a Flagship Peninsula Reef

The Peninsula S-950 G3+ provides a substantial foundation for marine fish displays, LPS and soft coral reefs, and appropriately equipped mixed reef systems. Its large display and three-sided viewing format require careful planning of lighting coverage, water circulation, aquascaping, equipment access, and the chosen split-sump configuration.

• Return pump reference: Red Sea specifies two ReefRun G2 12000 pumps in the corresponding MAX Peninsula S-950 G3+ equipment package. Return pumps are sold separately with the standard reef-ready system.
• Lighting reference: The equivalent MAX package uses four ReefLED G2 170 fixtures. Alternative lighting should provide suitable coverage and intensity over the 200 x 68 cm (78.7 x 26.8 inch) display.
• Protein skimmer reference: Red Sea specifies an RSK DC 900 for the MAX configuration. Alternative skimmers should be checked for the sump chamber dimensions and appropriate operating water depth.
• Supplementary circulation: The MAX package uses two ReefWave 45 pumps. Independently selected wavemakers should provide suitable circulation around the central aquascape and along the large aquarium.
• Freshwater storage planning: The included ATO Module requires a freshwater source. The extension sump can serve as an independent reservoir when configured for this purpose.
• Additional filtration: Optional ReefMat equipment, refugium expansion, dosing systems, and additional ReefSense probes can be planned around the aquarium's requirements.
• Installation support: Confirm that the chosen floor location can support the operating aquarium and that suitable freight access, lifting assistance, and maintenance space are available.
• Compared with the Peninsula S-700: The S-950 adds 49 cm (19.3 inches) of display length, substantially greater total system volume, and a configurable glass extension sump while retaining the premium aluminum cabinet and ReefControl Pro platform.
