RED SEA - Reefer 525 G3 Deluxe - White - 3 ReefLED 115 and 3 stems

RED SEA Reefer 525 G3 Deluxe reef aquarium: a premium format for a balanced marine project

The RED SEA Reefer 525 G3 Deluxe White was designed for aquarists who want a generously sized reef aquarium without sacrificing practicality. Measuring 150 cm long , 60 cm wide , and 55 cm high , it offers particularly appealing proportions for creating a spacious, well-defined, and elegant aquascape. Its total volume of 540 liters allows for better structuring of the reef landscape, provides more space for fish, and ensures more stable water parameters. This type of tank immediately adds another dimension to the project. The visual effect gains depth, the composition appears more natural, and the overall effect becomes a much more impressive addition to a living space.

Deluxe version with 3 ReefLED 115s and 3 brackets: homogeneous lighting across the entire facade

This Deluxe version comes with three ReefLED 115s and three mounting brackets , a particularly well-balanced configuration for effectively covering the entire length of the tank. In a 150cm reef aquarium, light distribution plays a crucial role in the overall look, the clarity of the aquascape, and the highlighting of different reef zones. With three well-distributed light sources, the lighting is more even, and the setup maintains a clean, modern, and seamless look. There's no need to search for a separate suspension solution, which significantly simplifies setup. The result is crisp, balanced, and visually stunning, with a presentation that immediately reinforces the system's premium character.

Red Sea G3 range: a technical evolution designed for greater comfort and reliability

The Red Sea G3 series represents a true evolution compared to previous generations. This isn't just a visual update. The entire design has been revamped to make the aquarium more user-friendly, easier to adjust, and more reassuring in the long run. 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 translates to a smoother, quieter, and frankly more enjoyable system to operate.

Ultra-clear 15mm glass tank and internal rim: a robust structure that enhances the reef

The Reefer 525 G3 Deluxe features an ultra-clear glass tank that immediately showcases the marine life, the rock formations, and the vibrant colors of the inhabitants. The front, sides, bottom, and back are all made of 15 mm glass , a particularly reassuring level of finish for an aquarium in this category. The beveled edges further enhance the impression of quality and underscore the premium positioning of the entire system. Like other REEFER G3 models over 400 liters, it benefits from internal bracing that improves the overall rigidity of the structure. The result is clean, crisp, and visually appealing, with a depth of field that instantly gives the reef a more commanding presence.

Marine-Spec cabinet made of marine plywood with aluminum front reinforcements: a reliable base built to last

The cabinet of the RED SEA Reefer 525 G3 Deluxe White aquarium does more than just complement the tank. It plays a vital role in the overall quality of the system. Made of marine plywood , it was designed to better withstand humidity and the specific stresses of a reef environment. The adjustable feet facilitate leveling, an essential feature for an aquarium of this size. Like the REEFER 525 and larger models, this tank also benefits from aluminum front reinforcements , a real plus for the overall rigidity of the structure. The white finish maintains a bright, clean, and elegant look, easily integrated into a modern interior. The entire setup inspires confidence and gives the impression of equipment built to last.

Optimized overflow and quieter water flow: cleaner everyday operation

For a marine aquarium installed in a living room, acoustic comfort is paramount. Red Sea has clearly addressed 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 smoothness. In practice, this results in quieter operation, efficient surface suction, and an overall impression of a cleaner, better-designed, and more pleasant system to live with.

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

The Reefer 525 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 system is properly balanced, the result is noticeably quieter operation. Simultaneously, the advanced hydrodynamic piping improves water circulation throughout the entire system. The dual-outlet configuration allows for the connection of one or two return pumps as needed. The total circulation pump and main pump are not included, providing significant customization options for creating a clean, cohesive setup perfectly suited to your reef aquarium project.

116-litre Reef-Spec ReefMat Ready settling tank: a modern and modular technical space

The Reef-Spec sump of the Reefer 525 G3 was designed to meet the current needs of reef aquarists. With its 116 liters , it offers ample technical space for organizing filtration without feeling cramped. It is Refugium-ready and ReefMat compatible , with a removable baffle that facilitates 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 tank. The skimmer, ReefMat, and main pump are not included, allowing you to build a system perfectly suited to your desired reef setup.

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 stability 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 marine project, it's a real plus on a daily basis.
