Red Sea Reefer Peninsula 500 G3 - Black Cabinet

Red Sea Reefer Peninsula 500 G3 - Black Cabinet

The Red Sea Reefer Peninsula 500 G3 - Black Cabinet is a premium 519 litre / 137.0 gallon reef-ready peninsula aquarium system for aquarists who want a larger three-sided room-divider display with euro-braced ultra-clear glass and a black marine-spec cabinet.

With a 125 cm length and broad 63.5 cm width, the Peninsula 500 G3 gives reef keepers more aquascaping room, more swimming space, and a stronger room-divider presence than the smaller Peninsula 350. This base REEFER Peninsula system includes a euro-braced 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 return nozzles, pre-assembled plumbing, and integrated ReefATO+ smart top-off control. Lighting, return pump, skimmer, heater, wavemakers, optional ReefMat, rock, sand, salt, and livestock are selected separately.

Red Sea REEFER Peninsula 500 G3 Black Reef System

• Larger peninsula display: The 500 G3 extends the room-divider concept to a 125 cm display, creating more visual impact and more usable reef space.
• Three-sided viewing: The aquascape can be enjoyed from both long sides and the end panel, making the system ideal for open rooms, feature walls, and divider-style installations.
• 519 litre total system volume: The larger water volume supports improved stability, more livestock planning flexibility, and stronger long-term reef potential.
• Black cabinet finish: The black marine-spec cabinet creates a bold high-contrast look that keeps attention on the reef.
• Custom equipment flexibility: This base package lets customers choose the exact lighting, return pump, skimmer, heater, flow, and control equipment they prefer.
• G3 reef-ready infrastructure: ReefGate control, optimized plumbing, quiet downflow, dual returns, ReefATO+, and a ReefMat-ready sump give the system a premium foundation.

Euro-Braced Ultra-Clear Peninsula Display

• 412 litre display volume: The main aquarium gives 108.8 gallons of reef space for larger aquascapes, coral colonies, open sand, and selected reef fish.
• 125 x 63.5 x 60 cm display: The longer footprint supports broader island layouts, extended rock structures, open channels, and more natural room-divider proportions.
• 15 mm glass build: The Peninsula 500 G3 uses 15 mm front, side, bottom, and back glass.
• Euro-braced format: The larger 500 model is euro-braced for added rigidity while maintaining a clean premium aquarium profile.
• Ultra-clear viewing: Low-iron glass improves clarity and reduces tint so coral colour and reef lighting show more accurately from multiple sides.
• Designed for display symmetry: Since both long sides are visible, rockwork and equipment placement should be planned to look clean from every viewing angle.

G3 Flow Architecture and ReefGate Control

• Hydrodynamically optimized piping: The G3 plumbing layout is designed for stronger, more efficient water movement from display to sump and back.
• Quiet rectangular downflow: The low-turbulence drain inlet helps reduce noise and makes the system easier to tune.
• ReefGate precision valve: Fine drain adjustment allows the overflow and sump water level to be tuned for quiet, stable operation.
• Central overflow with surface skimmer: The overflow pulls surface water into the filtration path and helps reduce film across the display.
• Curved dual side returns: The return outlets help sweep water along the long peninsula run and support better distribution through the display.
• Pre-assembled pipework: Factory-designed plumbing helps simplify setup and keeps the under-cabinet system organized.

REEF-SPEC Sump and ReefATO+ Stability

• 106.6 litre sump volume: The larger sump provides useful space for return equipment, skimmer selection, media, dosing lines, probes, and maintenance access.
• ReefMat-ready mechanical chamber: The mechanical filtration stage includes micron socks and media cups and is designed for optional ReefMat installation.
• Recommended ReefMat 500 path: The optional ReefMat 500 is the natural Red Sea roller-filter upgrade for this system.
• Integrated ReefATO+: ReefATO+ helps maintain stable water level and salinity while also providing temperature monitoring and leak detection.
• Flexible filtration layout: The sump supports protein skimming, carbon, media reactors, dosing, monitoring, and other equipment depending on the reef plan.
• Cleaner display area: Filtration equipment stays inside the cabinet so the visible three-sided aquarium remains clean and reef-focused.
