Description

The REEFER-S 850 G3 is a third-generation, ultra-large reef aquarium system designed for the serious aquarist. The S series is distinguished by its deeper and wider dimensions compared to the standard REEFER range, combined with superior structural and organizational features. The S-850 G3 offers ample space for elaborate aquascapes, while also being engineered for maximum performance, exceptional stability, and ultra-quiet operation.

Key Features of the S Series G3

Deeper and Wider Dimensions
The S-850 offers increased depth and width, allowing for more rock placement options, an open swimming area for fish, and optimal distance for coral growth. This added depth transforms the visual experience and enables spectacular three-dimensional aquascapes.

Aluminum Superstructure Furniture
The cabinet's central structure is a robust, marine-grade aluminum frame that reinforces the plywood exterior, ensuring maximum stability and complete safety for large volumes of water. This professional construction guarantees long-term durability, even in humid environments.

Ultra-Clear Lens with Euro-Brace Reinforcement
The REEFER-S 850 G3 features thick, ultra-clear glass with beveled edges and Euro-brace reinforcement along the top rim. Enjoy a vibrant, distortion-free view of your reef through this glass, designed for a modern and stylish look while offering exceptional strength and durability.

Sliding Control Panel
The S series cabinet incorporates a 60cm sliding control panel. This marine-spec panel offers a dedicated, organized and easily accessible space for mounting and managing electronic equipment and controllers, greatly simplifying installation and maintenance.

Integrated ReefATO+ System
The G3 models come standard with the advanced, app-controlled ReefATO+ system. This highly reliable, intelligent 3-in-1 device ensures stable salinity through a precise auto top-off system (solid-state sensor), accurate digital temperature monitoring, and highly sensitive leak detection (titanium probes).

Next Generation Water Management
The plumbing system has been completely redesigned for superior quietness and efficiency. The high-precision ReefGate™ valve on the main drain allows for fine-tuning and easy adjustments, ensuring stable water levels and near-silent operation. The optimized system with dual side returns and superior hydrodynamic piping provides up to 50% more water circulation and optimal distribution throughout the tank.

Reef-Spec Sump Ready for ReefMat
The REEF-SPEC professional glass sump incorporates a dedicated mechanical filtration compartment, perfectly sized for plug-and-play installation of a Red Sea ReefMat automatic roller filter (sold separately) or standard filters and media.

Ready-to-Assemble Plumbing
Includes all pre-cut piping with quick connections, eliminating the need for messy gluing or cutting during installation. Clean and quick installation guaranteed.
