Red Sea Reefer Peninsula S-700 G3 - White Cabinet

The Red Sea Reefer Peninsula S-700 G3 - White Cabinet is a premium 705 litre / 186.2 gallon reef-ready peninsula aquarium system that pairs a large three-sided REEFER-S G3 display with a bright white aluminum super-structure cabinet.

This base REEFER Peninsula S-Series system is designed for aquarists building a serious room-divider reef with their own selected equipment package. It includes a 151 cm euro-braced 19 mm ultra-clear glass aquarium, white aluminum super-structure cabinet, replaceable panels, hidden adjustable feet, slide-out control panel, REEF-SPEC sump, ReefMat-ready mechanical filtration chamber, micron socks, media cups, ReefGate precision valve, central overflow with removable surface skimmer, dual curved side returns, pre-assembled plumbing, and integrated ReefATO+ smart top-off control. Lighting, return pump, skimmer, heater, wavemakers, optional ReefMat, rock, sand, salt, livestock, and test kits are sold separately.

Red Sea REEFER Peninsula S-700 G3 White Room-Divider System

• Premium 151 cm peninsula format: The S-700 G3 provides a large room-divider reef display that can be viewed from both long sides and the end panel.
• 705 litre total system volume: The added volume supports more stable reef conditions and gives aquarists room for a larger coral and fish plan.
• White aluminum cabinet finish: The white cabinet creates a bright, modern, architectural look while retaining the stronger REEFER-S aluminum support platform.
• Three-sided reef presentation: This model is ideal for open-concept spaces where the aquarium is meant to define the room rather than sit against a wall.
• Custom equipment selection: Return pump, lights, skimmer, heater, wavemakers, dosing, control, and filtration upgrades can be chosen to match the reef plan.
• G3 Peninsula infrastructure: ReefGate, ReefATO+, optimized plumbing, dual side returns, low-turbulence downflow, and ReefMat readiness are built in.

Ultra-Clear Euro-Braced Peninsula Display

• 568 litre display volume: The display offers 150.0 gallons of aquarium space for a more mature aquascape, coral colonies, open sand, and selected reef fish.
• 151 x 68 x 65 cm dimensions: The 68 cm depth gives the reef a strong three-dimensional appearance from both long sides.
• 19 mm glass construction: Front, side, bottom, and back panels are listed at 19 mm for a strong premium display build.
• Euro-braced format: The reinforced top helps support the large display while maintaining a professional aquarium profile.
• Ultra-clear glass: Low-iron panels improve visual clarity and help reef lighting and coral colour show cleanly.
• Balanced aquascape potential: The peninsula layout encourages central structures, open channels, islands, and coral placement that looks finished from multiple angles.

White Aluminum Cabinet and Control Access

• Rigid aluminum super-structure: The cabinet uses Red Sea’s premium aluminum support system for added fortification across the long span.
• Replaceable white panels: The exterior panels give the system a clean furniture-style finish while remaining part of the modular cabinet design.
• Hidden adjustable feet: The leveling system helps the aquarium sit correctly on suitable flooring without disrupting the cabinet appearance.
• Slide-out control panel: The control panel gives a cleaner mounting point for controllers, power supplies, dosing hardware, and other reef devices.
• Service-friendly layout: The cabinet provides practical access for sump maintenance, power management, ReefATO+ components, and future equipment upgrades.
• Bright display style: The white finish visually lightens the large system and suits modern homes, offices, lobbies, and display spaces.

ReefGate Plumbing and Dual Side Returns

• Hydrodynamic G3 plumbing: The water-management system is designed for efficient movement from display to sump and back again.
• Quiet downflow inlet: The enlarged rectangular inlet reduces turbulence and helps the drain run more quietly when tuned.
• ReefGate precision valve: The downflow can be adjusted in small increments for stable, near-silent operation.
• Central overflow: The removable surface skimmer helps manage surface film and directs water into the filtration path.
• Curved dual side outlets: Side returns help move water across the long peninsula run and toward the far end of the display.
• Factory plumbing package: Pre-assembled plumbing makes installation cleaner and more predictable than designing a custom sump connection from scratch.

REEF-SPEC Sump and Smart ReefATO+

• 136.7 litre sump: The sump provides space for skimmer selection, return equipment, mechanical filtration, media, probes, dosing lines, and service access.
• ReefMat-ready mechanical stage: Micron socks and media cups are included, and the layout accepts an optional Red Sea ReefMat 1200.
• Integrated ReefATO+: ReefATO+ helps maintain stable water level and salinity while adding temperature monitoring and leak detection.
• Flexible filtration planning: The sump can support carbon, reactors, refugium-style nutrient export, dosing, and monitoring accessories.
• Clean three-sided display: Equipment stays below the tank so the visible aquarium remains focused on rockwork, coral, and livestock.
• Expandable reef foundation: The S-700 can be built as a simple large reef or expanded into a more automated Red Sea ecosystem.

Setup and Installation Notes

• Confirm placement first: Peninsula aquariums need access for viewing, cleaning, cabinet service, and freight positioning.
• Assemble and level the cabinet: Build the white aluminum cabinet according to Red Sea’s instructions and confirm it is level before placing the tank.
• Use the slide-out control panel: Plan controller, power-supply, and dosing-hardware placement before the system is fully stocked with equipment.
• Select equipment before filling: Choose return pump, skimmer, lighting, heater, wavemakers, optional ReefMat, and test kits before adding water.
• Install plumbing carefully: Confirm overflow, downflow, ReefGate valve, returns, sump, and ReefATO+ setup before filling.
• Leak test with freshwater: Run the aquarium and sump with freshwater before final saltwater setup.
• Tune the ReefGate gradually: Adjust the valve slowly until the overflow and sump run quietly.
• Use RO/DI water: RO/DI water is recommended for saltwater mixing and evaporation top-off.
• Cycle before livestock: Establish biological filtration before adding fish or corals.
