Red Sea Reefer Peninsula S-700 G3 - Black Cabinet

Red Sea Reefer Peninsula S-700 G3 - Black Cabinet

The Red Sea Reefer Peninsula S-700 G3 - Black Cabinet is a premium 705 litre / 186.2 gallon reef-ready peninsula aquarium system built for aquarists who want a large three-sided room-divider reef display with Red Sea’s reinforced REEFER-S G3 aluminum cabinet platform.

Designed for serious custom reef builds, the Peninsula S-700 G3 combines a 151 cm euro-braced 19 mm ultra-clear glass aquarium, black aluminum super-structure cabinet, replaceable panels, hidden adjustable feet, slide-out control panel, REEF-SPEC sump, ReefMat-ready mechanical chamber, micron socks, media cups, ReefGate precision valve, central overflow with removable surface skimmer, dual curved side return nozzles, pre-assembled plumbing, and integrated ReefATO+ smart top-off control. This is a base REEFER Peninsula S-Series system, so lighting, return pump, skimmer, heater, wavemakers, optional ReefMat, rock, sand, salt, livestock, and test kits are selected separately.

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

• Large peninsula display: The 151 cm length and three-sided viewing format make this system ideal for open-concept rooms, offices, lobbies, and feature reef installations.
• 186.2 gallon total system volume: The 705 L system volume provides strong stability for a mature mixed reef, LPS display, soft coral system, or SPS-capable build with proper lighting and flow.
• Black aluminum super-structure cabinet: The rigid aluminum cabinet support and black exterior panels create a high-end room-divider installation with a bold modern finish.
• Premium REEFER-S upgrade: Compared with the standard Peninsula models, the S-700 adds the aluminum cabinet platform, slide-out control panel, deeper display proportions, and 19 mm glass.
• Custom equipment freedom: Customers can choose their preferred return pump, lighting, skimmer, heater, wavemakers, dosing, control, and filtration upgrades.
• G3 water-management foundation: ReefGate tuning, optimized plumbing, low-turbulence downflow, dual side returns, ReefATO+, and ReefMat readiness are built into the system.

151 cm Euro-Braced Ultra-Clear Peninsula Display

• 568 litre display volume: The main aquarium provides 150.0 gallons of display space for coral colonies, open sand areas, rock islands, swim-throughs, and carefully selected reef fish.
• 151 x 68 x 65 cm dimensions: The long and deep footprint gives aquascapers room for a central reef structure that looks finished from both long sides.
• 19 mm glass specification: The S-700 G3 uses 19 mm front, side, bottom, and back glass for a substantial premium display build.
• Euro-braced construction: The reinforced top frame supports the larger peninsula display while maintaining a clean professional appearance.
• Ultra-clear viewing: Low-iron glass improves clarity and helps coral colour, fish movement, and reef lighting show with less tint.
• Room-divider aquascaping: The display should be planned as a three-dimensional reef, not a one-sided rock wall, so both viewing sides look complete.

Black Aluminum Cabinet and Slide-Out Control Panel

• Aluminum super-structure: The cabinet uses a robust aluminum support frame for extra fortification on the long peninsula span.
• Replaceable black panels: The exterior panels create a finished black cabinet look while remaining part of the modular REEFER-S cabinet design.
• Hidden adjustable feet: Leveling feet help the system sit correctly on suitable flooring while keeping the cabinet profile clean.
• Slide-out control panel: The integrated panel provides a dedicated location for mounting controllers, power supplies, dosing hardware, and smart reef accessories.
• Clean equipment organization: The cabinet layout supports a more serviceable installation with sump equipment, ATO hardware, cables, and future upgrades contained below the display.
• High-contrast presentation: The black cabinet visually frames coral colour and reef lighting while keeping attention on the aquarium.

G3 Peninsula Flow and ReefGate Control

• Hydrodynamically optimized plumbing: The G3 water path is designed for stronger and more efficient flow through the overflow, sump, and return system.
• Quiet rectangular downflow: The low-turbulence drain inlet helps reduce operating noise when properly tuned.
• ReefGate precision valve: Fine drain adjustment allows the overflow and sump level to be tuned for quiet, stable performance.
• Central overflow: The removable surface skimmer helps pull surface film and floating debris into the filtration path.
• Dual curved side returns: Side-mounted returns help sweep water along the peninsula layout and improve distribution toward the far end of the display.
• Single or dual return planning: The plumbing layout gives flexibility for the recommended ReefRun G2 12000 return strategy, sold separately.

REEF-SPEC Sump and ReefATO+ Stability

• 136.7 litre sump volume: The sump gives generous space for skimmer selection, return equipment, mechanical filtration, media, probes, dosing lines, and maintenance access.
• ReefMat-ready chamber: The mechanical filtration section 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.
• Flexible filtration planning: The sump can support skimming, carbon, reactors, refugium-style nutrient export, dosing, and monitoring equipment.
• Cleaner display area: Equipment is housed below the aquarium so the three-sided display remains focused on rockwork, coral, and fish.
• Long-term upgrade path: The system can start as a clean mixed reef and grow into a more automated Red Sea ecosystem over time.

Application Notes for the Peninsula S-700 G3

• Best use: Ideal for large room-divider reefs, mixed reef aquariums, LPS systems, soft coral displays, and SPS-capable builds with proper equipment.
