RED SEA - Reefer MAX 300 G3 - White

RED SEA Reefer MAX 300 G3 reef aquarium: a balanced size for a serious and elegant marine reef

The RED SEA Reefer MAX 300 G3 White is designed for those who want a truly high-end reef aquarium in a size that's still reasonable for a living space. At 90 cm long , 57.5 cm wide , and 55 cm high , it strikes a beautiful balance between visual presence, ease of setup, and simple integration. Its total volume of 300 liters allows for the creation of a rich coral aquascape, giving the display a greater sense of scale and providing much greater stability than a smaller tank. Fish gain more swimming space, corals breathe better visually, and the overall effect is immediately striking. This model has clearly been designed as a complete premium solution, conceived to offer enjoyment, stability, and true quality of operation every day.

MAX version with 2 ReefLED G2 115: precise, homogeneous reef lighting designed to enhance corals

This MAX version comes with two ReefLED G2 115s , a configuration perfectly suited to the tank's dimensions. In a 90cm aquarium, the lighting must be able to properly cover the entire aquascape, reveal its depth, and effectively support coral growth. The ReefLED G2s were designed with 100% Reef-Safe and 100% REEF-SPEC principles in mind, with a spectrum specifically formulated for corals. At full intensity, they can transition from a 10,000K reef white to a 23,000K REEF-SPEC blue . The result is clean, crisp, and vibrant, with a beautiful shimmer that immediately adds depth to the aquarium. For a tank of this size, this lighting provides true visual coherence and a solid foundation for the reef to thrive.

Red Sea G3 range: a technical evolution designed for greater stability, silence and comfort

The Red Sea G3 series represents a true step up in the world of complete reef aquariums. This isn't just a cosmetic upgrade. The entire technical architecture has been redesigned to make the system more user-friendly, more precise to adjust, and more reliable over time. The ReefATO+ is now included, making it easier to maintain a constant water level and stable salinity. The range also benefits from a ReefMat Ready sump , an optimized overflow , a new ReefGate valve , and advanced hydrodynamic piping . In a 300-liter reef aquarium, these improvements truly transform the experience. They contribute to quieter operation, better water circulation, more precise adjustments, and that highly satisfying feeling of having a well-designed system from the start.

Ultra-clear glass tank with a sleek, unreinforced design: a clean look and a very light visual line

The Reefer MAX 300 G3 features an ultra-clear glass tank that immediately showcases the reef aquascape. The 12mm front glass , 12mm sides , and 12mm base create a high-quality, robust, and solid impression. Colors stand out more, contrasts are more intense, and the depth of the aquascape becomes more defined. The fact that this model is unreinforced further enhances this impression of visual lightness. The eye moves freely, the surface appears more open, and the overall look is more elegant. For an aquarium in this category, this clean line works particularly well. It allows the reef to take center stage without the structure weighing down the overall design.

Marine-Spec white furniture: a neat, sturdy base, ideal for elegant integration

The cabinet of the RED SEA Reefer MAX 300 G3 White is an integral part of the system's overall quality. It has been designed to offer excellent durability in a marine environment while maintaining a truly elegant appearance. The replaceable exterior panels contribute to the refined finish, while the concealed adjustable feet facilitate leveling without compromising the aesthetic appeal. The white finish provides a bright, modern presence that is particularly easy to integrate into a contemporary interior. The tank thus maintains a premium, clean, and balanced look. With a 300-liter tank, this aspect is crucial, as the aquarium is often placed in a living space where the cabinet's elegance is just as important as the tank's technical performance.

Large overflow and more discreet water drain: a more pleasant aquarium to live in every day.

In a reef aquarium set up in a living room, noise and water flow quality make a real difference. Red Sea has therefore paid particular attention to water management in this model. The central overflow features a large intake surface and a removable comb that simplifies maintenance. The wide downpipes have been designed to minimize turbulence and thus reduce noise. Their rectangular inlet further improves the flow's fluidity. In practice, this translates into a cleaner, more stable, and significantly quieter system. It is precisely these details, sometimes barely noticeable on paper, that truly transform the user experience and make the tank more pleasant to admire day after day.

High-precision ReefGate valve and hydrodynamic piping: controlled circulation and easier adjustment

The Reefer MAX 300 G3 boasts exceptionally refined hydraulic management for an aquarium of this size. The new ReefGate valve , installed on the overflow, allows for precise and fine-tuned flow control. Once the optimal balance is achieved, the system becomes more stable, quieter, and much more pleasant to operate on a daily basis. Simultaneously, the advanced hydrodynamic piping ensures a powerful flow throughout the entire circuit. The piping can be connected to one or two return pumps , providing considerable flexibility to adapt to the reef's growth. The overall impression is one of high technical expertise, with consistent, modern circulation that is far more reassuring than a makeshift setup.

54-liter Reef-Spec sump: a compact, organized, and truly practical technical space

The Reefer MAX 300 G3 is equipped with a 54-liter Reef-Spec sump , designed to keep the equipment clear, easy to read, and simple to maintain. It is ReefMat Ready , refugium-ready , and features a height-adjustable skimmer compartment , micron bags , removable media cups , and a bubble trap . This space allows for the integration of equipment without a cluttered feel, while maintaining convenient access for maintenance. In a 300-liter aquarium, this organization truly makes a difference. It provides a premium, well-structured system that is more pleasant to use, especially when regular maintenance is required.

ReefWave 25 circulation pump: a silent, efficient reef flow perfectly suited to this format.

The two included ReefWave 25 pumps ensure consistent water flow tailored to the tank's dimensions and the biological needs of the corals. Their design delivers a substantial REEF-SPEC water flow , capable of effectively supporting even the most complex reef aquascapes. Their sine wave motors operate quietly, while vibration dampers and double-bearing rotors minimize vibrations. Control via ReefBeat allows you to adjust the flow rate according to the aquascape layout and the type of reef being created. In an aquarium of this size, this integrated flow system is a significant advantage. It provides a stable, reliable, and immediately usable foundation for building a vibrant and well-balanced reef.

RSK DC 300 skimmer and ReefRun G2 4000 pump: a consistent technical foundation for a stable reef

The included RSK DC 300 is designed to provide stable skimming, good oxygenation, and intelligent daily operation. Its self-regulating technology helps prevent over-skimming and reduces the risk of the collection cup overflowing while continuing to effectively oxygenate the water. Meanwhile, the ReefRun G2 4000 ensures powerful, discreet, and efficient pumping. It can be used locally via its integrated controller or connected to ReefBeat via the Dual Controller for more advanced control. This combination brings true coherence to the overall technical package of the MAX 300 G3. It allows you to start with a solid, modern, and reassuring foundation, without having to make complicated choices right from the start.

ReefMat 500 and ReefATO+: valuable automation for keeping an aquarium clean and stable

The included ReefMat 500 keeps the water clear thanks to its user-friendly automated mechanical filtration. Its filter roller replacement system is simple, quick, and clean, greatly simplifying routine maintenance. Meanwhile, the ReefATO+ precisely maintains the water level and salinity. It integrates a temperature probe and a highly sensitive leak detector , all controlled via ReefBeat . In a 300-liter reef aquarium, this automation is more than just a gimmick. It directly contributes to the overall stability of the system, providing true peace of mind every day.

Sliding control panel 60 included: clean technical organization and much simpler access

The 60mm sliding control panel is one of the details that makes the whole system significantly more user-friendly. It allows for a clean and organized mounting of the controllers , while also facilitating access to the equipment during maintenance and adjustments. On such a comprehensive system, having a clear, well-integrated, and easy-to-use control area is a real advantage. The inside of the cabinet remains tidier, the connections are better organized, and maintenance becomes simpler.
