Red Sea Reefer Peninsula 350 G3 - White Cabinet

The Red Sea Reefer Peninsula 350 G3 - White Cabinet is a premium 352 litre / 93.0 gallon reef-ready peninsula aquarium system that combines Red Sea’s compact three-sided display format with a bright white marine-spec cabinet and G3 reef infrastructure.

Designed as a room-divider reef aquarium, the Peninsula 350 G3 allows the aquascape to be viewed from both long sides and the end panel, making it a strong choice for open-concept rooms, offices, reception areas, and feature aquarium installations. This base REEFER Peninsula package includes a rimless 15 mm ultra-clear glass aquarium, white marine-spec plywood cabinet, REEF-SPEC sump, ReefMat-ready mechanical chamber, micron socks, media cups, ReefGate precision drain 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 sold separately.

Red Sea REEFER Peninsula 350 G3 White Room-Divider System

• Compact peninsula reef platform: The 350 G3 brings the room-divider aquarium concept into a manageable 96 cm length that works in more spaces than larger peninsula systems.
• Three-sided reef viewing: The aquarium is built to show the reef from both long sides and the end panel for a more open and immersive display.
• 93 gallon total system volume: The 352 L system volume gives reef keepers a stable foundation for a carefully selected livestock and coral plan.
• White cabinet finish: The white marine-spec cabinet creates a clean, bright, modern look that visually lightens the aquarium installation.
• Custom equipment freedom: This base system lets customers choose their preferred return pump, lighting, skimmer, heater, flow pumps, and automation hardware.
• G3 water-management platform: The system includes ReefGate control, hydrodynamic plumbing, quiet downflow design, dual returns, ReefATO+, and a ReefMat-ready sump.

Rimless Ultra-Clear 96 cm Display

• 278 litre display volume: The main aquarium provides 73.4 gallons of display space for a reef that can be enjoyed from multiple angles.
• 96 x 63.5 x 60 cm dimensions: The wide 63.5 cm footprint gives enough depth for island rockwork, caves, open channels, and negative-space aquascaping.
• 15 mm glass specification: The Peninsula 350 G3 uses 15 mm front, side, bottom, and back glass.
• Ultra-clear low-iron glass: The viewing panels help reduce colour distortion and improve the appearance of coral colour and reef lighting.
• Rimless display format: The clean open-top style gives the system a premium modern appearance with easy access for maintenance.
• Excellent room-divider proportions: The tank is compact enough to place thoughtfully while still offering the width needed for peninsula aquascaping.

G3 Plumbing and Dual Side Returns

• Hydrodynamic flow path: The G3 plumbing design is built to move water efficiently through the display, overflow, sump, and return system.
• Quiet rectangular downflow: The enlarged drain inlet reduces turbulence and helps the system run more quietly when tuned properly.
• ReefGate drain control: The precision valve allows fine adjustment of the downflow line for stable and near-silent sump operation.
• Surface-skimming overflow: The central overflow includes a removable surface skimmer to help pull film and floating debris into the filtration path.
• Dual side return nozzles: Curved side returns help distribute return flow along the peninsula viewing pane and across the open aquascape.
• Pre-assembled plumbing: Included pipework simplifies installation compared with designing custom plumbing from scratch.

REEF-SPEC Sump and ReefATO+ Control

• 74.6 litre sump volume: The in-cabinet sump provides practical space for mechanical filtration, skimmer selection, return equipment, media, probes, and dosing lines.
• ReefMat-ready chamber: The mechanical filtration compartment includes micron socks and media cups and is designed for optional Red Sea ReefMat installation.
• Integrated ReefATO+: ReefATO+ helps stabilize water level and salinity while adding temperature monitoring and leak detection.
• Flexible filtration planning: The sump supports carbon, media, skimming, monitoring accessories, and future automation upgrades.
• Cleaner display presentation: Support equipment is kept inside the cabinet so the three-sided display remains focused on the reef.
• Serviceable cabinet layout: The sump and plumbing are accessible from the cabinet area for regular maintenance and equipment adjustments.

Setup and Installation Notes

• Plan the room layout: Leave room for three-sided viewing, glass cleaning, cabinet access, and safe movement around the aquarium.
• Assemble and level the cabinet: Build the white cabinet according to Red Sea’s instructions and confirm it is level before placing the aquarium.
• Choose equipment before filling: Select the return pump, skimmer, lighting, heater, wavemakers, optional ReefMat, and controller layout before adding water.
• Install plumbing carefully: Confirm the overflow, downflow, ReefGate valve, return plumbing, sump, and ReefATO+ are correctly installed.
• Freshwater leak test: Run the system with freshwater before final saltwater setup to verify plumbing and sump operation.
• Tune the ReefGate slowly: Adjust the valve in small increments until the overflow and sump operate quietly.
• Use RO/DI water: RO/DI water is recommended for saltwater mixing and top-off.
• Cycle before stocking: Establish biological filtration before adding fish or corals.
