Description

The REEFER 350 G3 is a next-generation, all-in-one reef platform designed to provide a stable, quiet, and durable foundation for discerning aquarists. Building upon improvements to the G3 series, this system combines thicker, ultra-clear glass, a reinforced rimless design, and a marine-spec cabinet for long-term use. The plumbing is ready to assemble without glue, incorporating a quiet overflow and optimized water management. The system is eligible for an extended warranty and designed to accommodate modern accessories, including advanced filtration and automation.

The system's architecture emphasizes aesthetics and quiet operation. The water-resistant cabinet is designed for humid environments and features adjustable feet for precise leveling. Pre-assembled plumbing ensures a clean and quick installation, while fine-tuning the flow rate guarantees a consistent flow. A safe emergency overflow protects the system in case of flow fluctuations, reducing risks and noise while simplifying daily maintenance.

The integrated REEF-SPEC sump is designed as a true technical hub. It includes mechanical filtration with a dedicated compartment for micron filters and media, a skimmer chamber with adjustable water level, an efficient bubble trap to minimize microbubbles, and an integrated auto-top-off reservoir for reverse osmosis water. The design is plug-and-play and ready to accommodate a ReefMat system without modification, ensuring a simple upgrade to automated filtration.

The modular design of the REEFER 350 G3 allows for gradual automation and tangible long-term benefits. Reduced manual maintenance, increased water parameter stability, and extended clarity enhance the user experience. The system supports a higher organic load, is suitable for demanding SPS reefs as well as LPS or mixed tanks, and integrates seamlessly into high-end residential settings, showrooms, or specialty shops.

Designed for serious reef projects, this model is aimed at experienced aquarists seeking robustness, meticulous craftsmanship, controlled flow management, and advanced compatibility with modern equipment. It offers true peace of mind thanks to its proven design, quiet operation, and upgradeability.

In summary, the REEFER 350 G3 is a complete technological and aesthetic platform, designed for high-end reefs with few compromises, and capable of evolving according to the real needs and experience of the user.
