Red Sea Reefer 200 G3 - Black Cabinet

Red Sea Reefer 200 G3 - Black Cabinet

The Red Sea Reefer 200 G3 - Black Cabinet is a premium reef-ready aquarium and cabinet system for aquarists who want a compact but deeper sump-based reef platform with Red Sea’s third-generation water management and integrated ReefATO+.

With a 200 L / 52.8 gal total system volume and a deeper 57.5 cm display width, the REEFER 200 G3 gives reef keepers more aquascaping depth than the 170 while keeping the same 60 cm length. The system includes a rimless ultra-clear display, black 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 hardware.

Red Sea REEFER 200 G3 Black Reef System

• Deep compact reef platform: The REEFER 200 G3 keeps a space-friendly 60 cm length while increasing display width to 57.5 cm for a more spacious reef layout.
• 52.8 gallon total volume: The extra volume helps improve stability compared with smaller compact systems while staying manageable for maintenance.
• Black cabinet finish: The black marine-spec plywood cabinet creates a bold modern look and visually frames the reef display.
• Base-system freedom: Choose the lighting, return pump, skimmer, heater, wavemakers, controller, and dosing equipment that best match the reef you want to build.
• Sump-based expandability: The in-cabinet sump gives more equipment flexibility than most rear-chamber all-in-one tanks.
• Ideal for premium custom builds: The 200 is a strong size for aquarists who want a high-quality foundation before investing in lighting, flow, filtration, and automation hardware.

Deeper Ultra-Clear Display and Black Cabinet

• 158 L / 41.7 gal display: The display gives hobbyists more room for coral placement, rockwork, and livestock planning than smaller nano-class aquariums.
• 57.5 cm front-to-back width: The added depth allows for island structures, sloped rockwork, swim-throughs, shadow zones, and a more dimensional reefscape.
• Rimless ultra-clear glass: The display uses low-iron glass for a cleaner, brighter view of the reef.
• Modern beveled-edge styling: The rimless G3 design gives the system a clean display-tank appearance.
• Marine-spec cabinet: The black plywood cabinet includes leveling feet and is designed to support the aquarium and sump properly.
• Cleaner room presence: The dark cabinet helps hide shadows and equipment inside the stand while keeping the focus on coral colour and aquascape shape.

G3 Silent Downflow and ReefGate Valve

• Hydrodynamic G3 plumbing: The REEFER G3 water-management system is designed for improved circulation and reduced energy waste compared with earlier flow layouts.
• Quiet downflow inlet: The enlarged downflow design helps reduce turbulence and operating noise.
• ReefGate flow valve: The precision gate valve allows fine adjustment of the drain for stable, near-silent sump operation.
• Removable surface skimmer: The central overflow pulls from the surface to help remove film and support better gas exchange.
• Curved dual returns: Improved return nozzles help distribute return flow more naturally into the display.
• Pre-assembled plumbing: Factory-designed plumbing helps reduce installation guesswork and keeps the under-cabinet system organized.

REEF-SPEC Sump and ReefMat-Ready Filtration

• 42 L / 11.1 gal sump: The sump provides practical space for mechanical filtration, return pump, skimmer, media, and optional upgrades.
• Mechanical chamber included: Micron socks and media cups support simple mechanical and chemical filtration from the start.
• ReefMat-ready design: The mechanical chamber is designed for optional Red Sea ReefMat installation if automatic fleece-roll filtration is desired later.
• Integrated ReefATO+: The included smart ATO system helps maintain stable water level and salinity while adding temperature monitoring and leak detection.
• Flexible equipment bay: The sump-based format gives more room to plan skimming, media use, dosing, and maintenance access than a small rear-sump tank.
• Built for long-term reefkeeping: The system is designed as a foundation that can grow from a simple mixed reef into a more automated Red Sea ecosystem.
