Red Sea Reefer 170 G3 - Black Cabinet

Red Sea Reefer 170 G3 - Black Cabinet

The Red Sea Reefer 170 G3 - Black Cabinet is a premium compact reef-ready aquarium system for hobbyists who want Red Sea’s proven sump-based REEFER platform in a clean 60 cm footprint with a modern black marine-spec cabinet.

Designed as a serious foundation for a custom saltwater reef build, the REEFER 170 G3 combines a rimless ultra-clear glass display, reinforced cabinet construction, REEF-SPEC sump, ReefMat-ready mechanical filtration section, silent downflow system, ReefGate precision flow control, integrated ReefATO+, and an improved return/overflow layout. It is ideal for aquarists who want the flexibility to choose their own lighting, return pump, skimmer, heater, wavemakers, dosing equipment, and filtration upgrades while starting with a clean professional reef-ready tank and sump system.

Red Sea REEFER 170 G3 Compact Reef Foundation

• Premium compact reef system: The REEFER 170 G3 gives reef keepers a sump-based aquarium platform in a manageable 165 L / 43.6 gal total system size.
• Custom equipment flexibility: This base REEFER system lets you choose your own return pump, skimmer, lighting, heater, wavemakers, controller, and dosing equipment instead of locking you into a preconfigured MAX or Deluxe package.
• Black cabinet finish: The black marine-spec cabinet gives the system a clean, high-contrast look that helps equipment and shadows visually recede while coral colour stands out.
• Rimless display style: The smaller REEFER G3 models use a rimless format with smooth beveled edges for a clean modern presentation.
• Ideal first serious reef: The 170 is a strong choice for aquarists moving beyond basic all-in-one aquariums into a more expandable sump-based reef system.
• Red Sea ecosystem ready: The platform is designed to work naturally with Red Sea ReefRun pumps, REEFER skimmers, ReefLED lighting, ReefMat filtration, ReefATO+, and ReefBeat-connected devices when selected separately.

Ultra-Clear Rimless Display and Black Cabinet

• Compact 60 cm display: The 60 cm length makes the REEFER 170 G3 easy to place in homes, condos, offices, reception areas, and smaller reef spaces.
• 128 L / 33.8 gal display volume: The display size gives enough room for a refined aquascape, small reef fish, soft corals, LPS corals, and carefully planned mixed reef layouts.
• Ultra-clear glass construction: The low-iron viewing panels improve clarity and reduce the greenish tint associated with standard glass.
• Balanced reef proportions: The 60 x 50 x 51 cm display provides useful front-to-back depth for rockwork, coral islands, open sand areas, and natural negative space.
• Marine-spec plywood cabinet: The cabinet is designed for aquarium use with leveling feet to help create stable support on suitable flooring.
• Modern black furniture look: The black finish pairs well with dark furniture, entertainment rooms, office spaces, and high-contrast reef displays.

G3 Water Management and Quiet Operation

• Redesigned flow system: REEFER G3 systems use improved hydrodynamic piping and water management designed for stronger circulation and more efficient operation.
• Silent downflow design: The enlarged rectangular inlet to the downflow pipe helps reduce turbulence for quieter operation.
• ReefGate precision valve: The bespoke gate valve allows fine downflow adjustment so the system can be tuned for stable, near-silent sump operation.
• Central overflow: The overflow includes a removable surface skimmer to help remove film from the water surface and improve gas exchange.
• Curved return outlets: Improved return outlets help distribute water more effectively back into the display.
• Pre-assembled plumbing: The included downflow and return plumbing helps simplify setup compared with sourcing plumbing parts separately.

REEF-SPEC Sump and ReefATO+ Control

• Glass sump included: The REEFER 170 G3 includes a REEF-SPEC sump designed for efficient filtration, equipment placement, and day-to-day maintenance.
• ReefMat-ready mechanical chamber: The sump’s mechanical filtration compartment includes micron socks and media cups and is designed for optional ReefMat installation.
• Optional refugium capability: The sump layout supports flexible filtration planning for nutrient export, media use, and advanced reef equipment.
• Integrated ReefATO+: The included smart ATO system helps stabilize water level and salinity while adding temperature monitoring and leak detection functionality.
• Cleaner cabinet organization: A dedicated sump cabinet keeps filtration equipment, plumbing, ATO components, and future upgrades contained below the display.
• Upgrade-friendly design: The system is ready for a more advanced reef build with optional skimmer, return pump, roller filtration, dosing, and monitoring equipment.
