Red Sea REEFER Peninsula S-700 G3 – Ultra-Premium Large Room-Divider Reef System

The Red Sea REEFER Peninsula S-700 G3 is a flagship dual-view reef aquarium engineered for serious reef keepers and high-end display environments. Designed as a true room divider, this model offers unobstructed viewing from both sides, featuring a massive 185-gallon (700 L) ultra-clear rimless display and a total system volume of approximately 215 gallons (800+ L), including the sump and filtration infrastructure.

The S-Series G3 line features some of Red Sea’s most advanced engineering, including low-iron, ultra-clear glass panels up to 19 mm thick, reinforced marine-spec cabinetry with an aluminum frame, and oversized Euro-bracing for maximum structural integrity. Designed for long-term installations, the S-700 G3 combines museum-level clarity with industrial-grade durability.

The hydrodynamic plumbing system features dual return outlets, a high-capacity overflow box, and a precision downflow valve, ensuring whisper-quiet operation. The oversized REEF-SPEC sump accommodates large skimmers, refugiums, reactors, roller mats, UV sterilizers, and high-flow return pumps—making it ideal for advanced or heavily stocked reef ecosystems.

With its commanding length, panoramic visibility, and advanced mechanical infrastructure, the REEFER Peninsula S-700 G3 is the perfect foundation for SPS-dominant systems, mixed reef showpieces, large coral colonies, or luxury architectural installations.
