Red Sea Reefer Peninsula 350 G3 - Black Cabinet

Red Sea Reefer Peninsula 350 G3 - Black Cabinet

The Red Sea Reefer Peninsula 350 G3 - Black Cabinet is a premium 352 litre / 93.0 gallon reef-ready peninsula aquarium system designed for aquarists who want a compact room-divider reef display with Red Sea’s G3 water-management platform and a clean black marine-spec cabinet.

Built to be viewed from three sides, this peninsula-style REEFER system is ideal for open-concept spaces, living rooms, offices, and feature displays where the aquarium is meant to divide a room rather than sit flat against a wall. The system includes a rimless 15 mm ultra-clear glass aquarium, black marine-spec plywood cabinet, REEF-SPEC sump, ReefMat-ready mechanical chamber, micron socks, media cups, ReefGate precision valve, central overflow with removable surface skimmer, curved dual side returns, pre-assembled plumbing, and integrated ReefATO+ smart top-off control. Lighting, return pump, skimmer, heater, wavemakers, optional ReefMat, livestock, rock, sand, and salt are selected separately.

Red Sea REEFER Peninsula 350 G3 Black Room-Divider System

• Three-sided peninsula viewing: The Peninsula 350 G3 is designed to be viewed from both long sides and the end panel, creating a more immersive reef display than a standard wall-facing aquarium.
• Compact room-divider footprint: The 96 cm length makes it easier to place than larger peninsula tanks while still giving the reef a strong architectural presence.
• 352 litre total system volume: The 93.0 gallon system volume provides a stable foundation for a carefully planned reef aquarium.
• Black cabinet presentation: The black marine-spec cabinet creates a high-contrast look that helps coral colour, aquascape shape, and reef lighting stand out.
• Base-system flexibility: Return pump, lighting, skimmer, heater, flow pumps, dosing equipment, and automation can be chosen separately around the customer’s reef goals.
• G3 reef infrastructure: Hydrodynamic plumbing, quiet downflow design, ReefGate control, ReefATO+, and a ReefMat-ready sump give the system a strong modern Red Sea foundation.

Rimless Ultra-Clear Peninsula Display

• 278 litre display volume: The main display gives 73.4 gallons of reef space for coral placement, open sand areas, rock islands, swim-throughs, and selected reef fish.
• 96 x 63.5 x 60 cm dimensions: The generous 63.5 cm width gives the aquascape useful depth for a three-sided room-divider layout.
• 15 mm glass construction: The Peninsula 350 G3 uses 15 mm front, side, bottom, and back glass.
• Rimless ultra-clear format: Low-iron glass and the rimless top give the aquarium a clean premium look with excellent viewing clarity.
• Designed for island aquascapes: The layout is well suited to central rock structures, negative space, caves, open channels, and coral placement visible from multiple angles.
• Open-top access: The rimless design makes aquascaping, maintenance, feeding, and coral placement more convenient.

G3 Water Management and Peninsula Flow

• Hydrodynamically optimized piping: Red Sea’s G3 water path is designed for stronger, more efficient circulation through the overflow, sump, and return path.
• Low-turbulence downflow: The enlarged rectangular drain inlet helps reduce turbulence and supports quieter running once the system is tuned.
• ReefGate precision valve: The high-precision downflow valve allows fine control of the drain line for stable, near-silent overflow operation.
• Central overflow with surface skimmer: The overflow pulls surface water into the filtration path and helps reduce surface film.
• Curved dual side returns: The side return outlets help move water along the peninsula viewing pane and reduce dead zones when paired with proper wavemaker flow.
• Pre-assembled plumbing: The included pipework gives the system a clean factory-designed drain and return layout.

REEF-SPEC Sump and ReefATO+ Stability

• 74.6 litre sump volume: The sump gives dedicated space for mechanical filtration, skimmer selection, return equipment, media, probes, and maintenance access.
• ReefMat-ready mechanical chamber: The removable mechanical compartment includes micron socks and media cups and is designed for optional ReefMat installation.
• Integrated ReefATO+: ReefATO+ helps manage evaporation-driven water-level changes and salinity stability while adding temperature monitoring and leak detection.
• Flexible filtration planning: The sump can support skimming, carbon, media, dosing lines, monitoring probes, and future filtration upgrades.
• Cleaner equipment layout: The cabinet sump keeps filtration and support equipment below the display instead of crowding the reef view.
• Room-divider service access: The system should be positioned with enough room for cabinet, sump, plumbing, and glass maintenance from the appropriate sides.
