Red Sea REEFER S-1000 G3 – Flagship 1000-Litre Ultra-Premium Reef System

The Red Sea REEFER S-1000 G3 is the crown jewel of the REEFER lineup—an ultra-premium, large-format reef system built for advanced reef keepers and high-end showpiece installations. With an enormous 264-gallon (1,000 L) ultra-clear rimless display and a total system volume exceeding 330 gallons (1,250+ L) including the sump, the S-1000 G3 offers unmatched space for complex aquascapes, large coral colonies, and long-term SPS-dominant builds.

This flagship model features heavy-duty low-iron glass up to 19 mm thick, providing exceptional clarity, strength, and a truly immersive viewing experience. The reinforced marine-spec plywood cabinet, combined with an internal aluminum support frame, delivers superior rigidity and long-term stability—ideal for large, permanent installations.

The advanced plumbing system features high-capacity dual return outlets, an oversized overflow chamber, and a precision downflow valve, ensuring whisper-quiet operation. The extra-large REEF-SPEC sump is designed to house full-size skimmers, large refugiums, roller filters, reactors, UV sterilizers, and high-output return pumps, making it one of the most capable sump systems on the market.

The system also integrates the ReefATO+ (auto top-off, temperature monitoring, leak detection), ensuring added redundancy and system stability. With its massive display area, premium materials, and professional-level infrastructure, the REEFER S-1000 G3 is built to support the most demanding reef environments.
