Red Sea REEFER 250 G3

The Red Sea REEFER 250 G3 is a premium, reef-ready display system designed for hobbyists seeking high-end performance, clarity, and built-in infrastructure in a compact footprint. With a display tank volume of 53.6 gallons (203 L) and a total system volume of approximately 64.7 gallons (245 L), including the sump and plumbing, this model provides ample space for advanced aquascaping, dense rock work, and thriving coral colonies.

Crafted with ultra-clear, low-iron, rimless glass and a marine-spec plywood cabinet, this system is designed to elevate both aesthetics and performance. The G3 series introduces enhanced plumbing flow, featuring hydrodynamically optimized piping for up to 50% more circulation. It also includes a precision gate valve (ReefGate) for quiet tuning and dual curved return outlets, providing wide distribution and reduced dead spots.

The included REEF-SPEC sump features a mechanical sock stage, media chamber, surface skimmer and pre-plumbed return line—giving you a strong foundation for adding skimmers, reactor loops, refugiums and advanced filtration. Whether your focus is mixed-reef, LPS/soft coral gardens, or stepping into SPS territory, this system sets the stage for enduring reef success with clarity, reliability, and modern design.
