Red Sea REEFER G3 Design — Built for Everyday Reefing Success

This third-generation design upgrades the already proven REEFER platform with smoother plumbing and refined construction. The Red Sea REEFER 250 G3 offers ultra-clear beveled glass panels and a rimless layout for a panoramic reef view. Its low-profile overflow keeps hardware hidden, while the updated ReefGate Flow Valve quietly regulates water movement for balanced circulation and sound-free operation.

The included ReefATO+ Auto Top-Off System combines precision sensors, leak detection, and temperature tracking in one connected package through the ReefBeat App—smart technology that keeps your environment stable without extra effort.

Red Sea REEFER 250 Black Cabinet — Strength with Style

The Red Sea REEFER 250 Black cabinet matches its minimalist display with durable marine-grade plywood and moisture-resistant lamination. Stainless-steel hinges and adjustable leveling feet ensure stability and long-term use, even in high-humidity rooms.

Inside the stand, a clean glass sump layout leaves room for customization. The system is compatible with ReefMat 250 fleece filters and REEFER DC protein skimmers, giving aquarists flexibility to build or expand their filtration setup without modification.

Red Sea REEFER 250 G3 Filtration — Smart, Silent, and Efficient

The Red Sea REEFER 250 G3 Aquarium System in Black features pre-assembled plumbing that snaps together easily—no messy gluing required.

• ReefGate Flow Valve simplifies drain adjustment for smooth, quiet performance.

• ReefATO+ System maintains consistent water level, temperature, and leak protection.

• Adjustable Skimmer Chamber and refugium-ready sump encourage biological stability.

These upgrades make the 250 G3 not only easier to maintain but also more energy-efficient and customizable for future reef expansions.

Red Sea REEFER 250 G3 Viewing Experience — Clarity That Speaks for Itself

Every inch of this aquarium highlights coral texture and fish color with distortion-free glass. The 65-gallon layout strikes the right balance between display presence and manageable maintenance. A hidden overflow and improved flow paths reduce noise, keeping attention where it belongs—on your reef, not your return pump.
