Red Sea Reefer 350 G3 - White Cabinet

Red Sea Reefer 350 G3 - White Cabinet

The Red Sea Reefer 350 G3 - White Cabinet is a premium 342 litre / 90.3 gallon reef-ready aquarium and cabinet system that gives aquarists the largest rimless classic REEFER G3 display with a clean white marine-spec cabinet.

Designed for hobbyists who want a longer reef display while preserving the open rimless look, the REEFER 350 G3 combines a 120 cm ultra-clear glass aquarium, white marine-spec plywood cabinet, REEF-SPEC sump, ReefMat-ready mechanical filtration chamber, pre-assembled plumbing, ReefGate precision valve, surface-skimming overflow, curved dual return nozzles, and integrated ReefATO+ smart top-off control. It is a refined base platform for a custom reef aquarium where the final light, pump, skimmer, heater, flow, and automation choices stay in the customer’s control.

Red Sea REEFER 350 G3 White Reef System

• Largest rimless G3 format: The 350 is the largest rimless model in the classic REEFER G3 lineup before the range moves into euro-braced displays.
• 120 cm display length: The longer display creates better room for natural fish movement, coral spacing, and broader aquascape design.
• White cabinet finish: The white marine-spec cabinet gives the aquarium a bright, modern look that works well in contemporary homes, offices, and display spaces.
• Base-system flexibility: Return pump, skimmer, lighting, heater, wavemakers, dosing, and monitoring equipment are chosen separately for a tailored reef build.
• Sump-based platform: The included REEF-SPEC sump gives more equipment flexibility than compact all-in-one rear chambers.
• Strong long-term size: The 350 offers enough volume and display space for a mature reef while remaining more manageable than larger 5 foot and 6 foot systems.

Long Ultra-Clear Display with White Cabinet Styling

• 273 litre display volume: The main display gives reef keepers more room for coral growth, selected fish, and a more open reefscape.
• 120 x 50 x 53 cm footprint: The longer format supports reef ridges, islands, swimming lanes, and wider coral gardens.
• Reinforced rimless glass specification: The model is listed with 12 mm front glass, 15 mm side glass, and 12 mm bottom glass.
• Ultra-clear glass: Low-iron panels improve viewing clarity and reduce tint so coral and fish colour show more accurately.
• Bright furniture-style appearance: The white cabinet visually lightens the system and helps it blend into modern interiors.
• Clean display focus: Sump equipment sits below the tank, keeping the visible display free of bulky filtration hardware.

G3 Silent Downflow and Improved Water Return

• Improved hydrodynamic system: REEFER G3 plumbing is redesigned for stronger circulation and improved efficiency.
• Quiet rectangular downflow: The enlarged drain inlet helps reduce turbulence and supports quieter operation.
• ReefGate flow valve: The precision valve allows fine-tuning of the drain line to stabilize the overflow and sump water level.
• Surface-skimming overflow: The central overflow includes a removable surface skimmer to help remove surface film.
• Curved dual return nozzles: The improved return outlets help distribute water back into the longer 120 cm display.
• Pre-assembled plumbing: Included downflow and return plumbing makes installation cleaner and more predictable than a fully custom plumbing layout.

REEF-SPEC Sump and ReefATO+ Control

• 69 litre sump: The sump gives room for skimmer selection, return pump installation, mechanical filtration, media, dosing lines, probes, and optional upgrades.
• ReefMat-ready chamber: The mechanical filtration section includes micron socks and media cups and can be upgraded with optional Red Sea ReefMat filtration.
• Integrated ReefATO+: ReefATO+ helps stabilize sump water level and salinity while also offering temperature monitoring and leak detection.
• Flexible filtration planning: The sump supports a variety of reef setups, from simple mixed reefs to more automated coral-focused systems.
• Maintenance access: Cabinet sump access makes skimmer service, filter maintenance, dosing, and equipment changes more practical.
• Expandable Red Sea ecosystem: The system pairs naturally with optional ReefRun, ReefLED, ReefMat, ReefWave, ReefDose, and ReefBeat-connected devices.
