RED SEA - Reefer 350 G3 - White - 342L

RED SEA Reefer 350 G3 White Reef Aquarium: a premium size for a custom marine project

The RED SEA Reefer 350 G3 White was designed for those who want a serious, elegant, and spacious reef aquarium, large enough to create a true marine project without resorting to an overly imposing setup. Measuring 120 cm long , 50 cm wide , and 53 cm high , it offers a particularly well-balanced format for creating a harmonious, clear, and natural aquascape. Its total volume of 342 liters already provides ample room to create a vibrant, well-organized reef that is a pleasure to observe every day. This capacity allows for better structuring of the aquascape, provides comfortable swimming space for the fish, and offers greater stability than a more compact tank. The overall effect is truly premium while remaining perfectly balanced for placement in a living space.

Red Sea G3 range: a technical evolution that improves comfort and reliability

The Red Sea G3 series represents a true evolution in the approach to premium reef aquariums. This isn't just a cosmetic refresh. The entire design has been revamped to make the system more user-friendly, easier to adjust, and more reliable for everyday use. The ReefATO+ is now included, helping to maintain a constant water level and stable salinity—two essential parameters in a marine aquarium. The G3 generation also features a ReefMat Ready sump , a redesigned overflow , a new ReefGate valve , and improved hydrodynamic piping . In practice, this is immediately noticeable: the system feels smoother, quieter, more user-friendly, and overall much more refined.

Ultra-clear 12-15 mm glass tank: a crisp reef view and a premium finish

The Reefer 350 G3 White features an ultra-clear glass tank that immediately highlights the details of the aquascape, the colors of the corals, and the presence of the fish. The front is made of 12 mm glass , while the sides are 15 mm . The bottom and back are also 12 mm glass , giving the tank a solid, cohesive structure perfectly suited to its size. The beveled edges further enhance the perceived quality and give the aquarium a very refined look. This model maintains an elegant and light profile, while also inspiring confidence. The result is visually clean, with a beautiful depth that immediately emphasizes the presence of the reef.

Marine-Spec white furniture made of marine plywood: a durable, clean and reassuring base

The cabinet of the RED SEA Reefer 350 G3 White is an integral part of the system's overall quality. Made of marine plywood , it has been designed to better withstand humidity and the specific stresses of a reef environment. The adjustable feet facilitate leveling, which is particularly useful when setting up an aquarium. The white finish provides a bright, clean, and elegant look that easily integrates into many interiors. The entire setup conveys a sense of quality, with a cabinet that is not only aesthetically pleasing but also contributes to the long-term stability and reliability of the installation.

Optimized overflow and quieter water flow: a more pleasant aquarium to live in

For a marine aquarium installed in a living room, acoustic comfort is paramount. Red Sea has clearly focused on this aspect with the Reefer G3 . The plumbing is concealed within a large overflow with an overflow and surface suction, equipped with wide, removable combs for easy cleaning. The downpipes have been redesigned to reduce turbulence and therefore flow noise. Their rectangular inlet profile further improves the flow's fluidity. In practice, this results in a more discreet, smoother, and much more pleasant system for everyday use. This kind of detail truly transforms the experience when an aquarium is placed in a living room or office.

High-precision ReefGate valve and advanced hydrodynamic piping for better-controlled circulation

The Reefer 350 G3 benefits from modernized hydraulic management for simpler adjustments and a more pleasant user experience. The new ReefGate valve , installed on the overflow, allows for much more precise flow adjustment. Once the correct balance is achieved, operation becomes significantly quieter. Simultaneously, the advanced hydrodynamic piping improves water circulation throughout the entire system. The 25mm return outlets, standard on this size range, ensure consistent and well-designed circulation. The dual-outlet configuration allows for the connection of one or two return pumps, depending on requirements. The total circulation system and main pump are not included, providing complete freedom to create a system perfectly suited to your reef aquarium project.

69-liter Reef-Spec ReefMat Ready sump: a modern and practical technical space

The Reef-Spec sump of the Reefer 350 G3 was designed to offer a clear, logical, and user-friendly technical space. With its 69-liter capacity , it provides ample room for organizing the filtration system while maintaining good visibility. It is Refugium-ready and ReefMat compatible , with a removable side panel allowing for the quick installation of a ReefMat 250, 500, or 1200. It also features a height-adjustable skimmer compartment , micron bags , a removable media cup , and a bubble trap to prevent microbubbles from returning to the main sump. The skimmer, ReefMat, and main pump are not included, allowing for a truly customized setup tailored to the specific needs of your tank.

ReefATO+ included and smart control via ReefBeat: enhanced stability for everyday use

All G3 models now come equipped with ReefATO+ , a real advantage for a marine aquarium of this size. This system helps maintain a constant water level and stable salinity , two essential parameters for the comfort of the tank's inhabitants and the overall balance of the reef. It also integrates a precise temperature probe and a high-sensitivity leak detector , further enhancing the system's safety. Control via the ReefBeat app adds a highly practical dimension for monitoring the system and keeping an eye on important parameters. For an ambitious reef project, it offers true daily convenience.
