RED SEA - Reefer 750 G3 Deluxe - Black - 750L - 4 ReefLED 115 and 4 stems

RED SEA Reefer 750 G3 Deluxe: a premium reef aquarium for an ambitious marine project

The RED SEA Reefer 750 G3 Deluxe is designed for those who want to build a large-scale marine reef with a reliable, elegant, and well-thought-out foundation. Measuring 180 cm long , 65 cm wide , and 60 cm high , it offers a generous volume that allows for a structured and expansive aquascape, better distribution of corals, and significantly more comfortable swimming space for fish. This format clearly transforms the tank's appearance in a room. The aquascape feels more spacious, the perspectives are more natural, and the overall visual presence is enhanced. With an aquarium of this size, the system's overall stability is also much more reassuring, making it an excellent foundation for a long-term reef project.

Deluxe version with 4 ReefLED 115s and 4 brackets: well-distributed lighting along the entire length of the tank

This Deluxe version comes with four ReefLED 115 lights and four mounting brackets , a particularly attractive configuration for a 180cm aquarium. Distributing the light across four points provides wider coverage across the entire front panel, resulting in a visually balanced and clean installation. The overall look is modern, refined, and consistent with the tank's prestige. For reef aquarists who want a pre-structured system, this version allows for a more relaxed approach to lighting setup without the need to find additional solutions for suspending the lights. The result is clean, harmonious, and enhances both the tank and the surrounding aquascape.

RED SEA G3 range: a generation designed for greater comfort, quietness and control

The REEFER G3 series marks a true evolution in the approach to premium reef aquariums. Red Sea hasn't simply tweaked the design; the entire system has been redesigned to be more user-friendly, more stable, and easier to upgrade over time. This generation features advanced hydrodynamic piping , a high-precision ReefGate valve , improved water circulation, and a more modern approach to sump management. All of this is noticeable in everyday use. The tank is easier to set up, more comfortable to operate, and far more suitable for a serious reef setup.

Ultra-clear 19mm glass tank: a clear view of the reef and a reassuring structure

The Reefer 750 G3 Deluxe features a 19mm ultra-clear glass tank on the front, sides, bottom, and back. This thickness immediately inspires confidence, especially in an aquarium of this size. It also contributes to the tank's high-quality appearance, with sharper definition of colors, textures, and the depth of the aquascape. The beveled edges further enhance the feeling of a refined finish. On models larger than 400 liters, Red Sea adds an internal band that improves the overall rigidity of the structure. The result is a visually clean and elegant aquarium, designed to offer safety, durability, and enhanced reef visibility.

Cabinet made of marine plywood and reinforced structure: a reliable base for a 750-litre aquarium

The cabinet of the RED SEA Reefer 750 G3 Deluxe isn't just for show. It's an integral part of the system's sturdiness. Made of marine plywood , it's designed to better withstand ambient humidity and the specific demands of a marine aquarium. Adjustable feet make leveling easy, a crucial point for a setup of this size. On models in this category, the structure also benefits from front aluminum reinforcements , further enhancing its robust feel. The final result is very clean, with true visual coherence between the tank, the cabinet, and the entire setup.

Large overflow and optimized water drainage: a more discreet and pleasant aquarium to live in

On a reef aquarium set up in a living room, operating noise can quickly become a real issue. Red Sea has therefore addressed this point with care. The Reefer 750 G3 features a large overflow that integrates the overflow and surface suction, with wide, removable combs that are easy to detach for maintenance. The downpipes have been redesigned to reduce turbulence and improve water flow. Their rectangular inlet profile also contributes to a smoother flow. In practice, this translates into cleaner, quieter, and more convenient daily operation.

ReefGate and advanced hydrodynamic piping: precise flow control and efficient circulation

The Reefer 750 G3 is equipped with the new ReefGate valve , a high-precision valve installed on the downpipe for fine-tuning the flow rate with significantly improved ease of use. This is a real advantage for achieving stable and virtually silent operation. In addition, the advanced hydrodynamic piping has been designed to maintain smooth and efficient circulation throughout the entire system. The 32 mm return pump outlets allow for excellent water mixing capacity, with the option of installing one or two return pumps depending on the desired configuration. The total circulation system and main pump are not included, giving users the freedom to choose a configuration perfectly suited to their project.

150-liter Reef-Spec sump: a modern, modular, and ReefMat-compatible technical space

The cabinet incorporates a 150-liter sump designed for optimal operating comfort. This Reef-Spec sump is both Refugium-ready and ReefMat-ready , with a removable baffle that simplifies the installation of a ReefMat 250, 500, or 1200. The technical area also includes a height-adjustable skimmer compartment , micron bags , a removable media cup , and a bubble trap to prevent microbubbles from returning to the main tank. The skimmer, ReefMat, and main pump are not included, allowing you to freely choose the equipment best suited to your reef setup. This flexibility is particularly appealing to those who like to create a custom system.

ReefATO+ included and ReefBeat control: more serene stability for everyday use

The ReefATO+ is included with this model, and it's a truly essential piece of equipment for a marine aquarium of this size. It helps maintain a stable water level and consistent salinity , two crucial elements for a healthy reef ecosystem. The system is controlled via the ReefBeat app, adding a highly convenient feature for monitoring important parameters. It also integrates a precise temperature probe and a high-sensitivity leak detector , further enhancing the system's safety. For a large reef aquarium project, this type of equipment provides real peace of mind on a daily basis.

A RED SEA upgradeable aquarium for building a premium reef without compromise

The RED SEA Reefer 750 G3 Deluxe Black was designed as a premium base, capable of supporting a demanding reef project over the long term. This version, with four ReefLED 115 lights and four mounting brackets, already offers a coherent lighting solution, while allowing considerable freedom in the choice of other technical components. Circulation, the main pump, the skimmer, the ReefMat, and the sliding control panel are not included, allowing for customization of the setup to suit individual preferences. With its ultra-clear tank, robust structure, modern sump, and the improvements specific to the G3 generation, this model provides a particularly solid foundation for creating an elegant, high-performing, and long-lasting reef aquarium.
