RED SEA - Reefer 525 G3 Deluxe - White - 540 liters - 2 ReefLED 170 and 2 jibs

The RED SEA Reefer 525 G3 Deluxe White was designed for aquarists who want a truly impressive reef tank without it becoming too overwhelming for everyday use. Measuring 150 cm long , 60 cm wide , and 55 cm high , it offers a particularly appealing balance between visual impact, ease of maintenance, and flexibility in arranging the tank. Its total volume of 540 liters allows for a much larger display than a standard tank, with real perspective, better distribution of colonies, and more swimming space for the fish. This type of capacity clearly transforms the tank's appearance: the whole setup looks more stable, more mature, and far more spectacular in a living space.

Deluxe version with 2 ReefLED 170s and 2 brackets: a coherent and ready-to-use reef lighting system

This Deluxe version comes with two ReefLED 170s and two mounting brackets , providing a cohesive lighting setup that spans the entire length of the tank. In a 150cm reef aquarium, the quality of light distribution plays a crucial role in the overall appearance, the clarity of the aquascape, and the highlighting of different reef areas. Having a pre-designed system from Red Sea makes installation much easier. The setup remains clean, modern, and well-integrated, eliminating the need for separate suspension solutions. The result is crisp, balanced, and visually stunning, with a presentation that immediately reinforces the premium character of the aquarium.

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 refresh. 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.

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

The Reefer 525 G3 Deluxe features an ultra-clear glass tank that immediately enhances the depth of the aquascape and the vibrant colors of the aquatic life. The front, sides, bottom, and back are all made of 15mm glass , a high level of finish for an aquarium in this category. The beveled edges contribute to the impression of quality and reinforce the tank's premium look. Like other REEFER G3 models over 400 liters, it benefits from internal bracing that improves the overall rigidity of the structure. The result is reassuring, clean, and visually very appealing. The reefscape gains clarity, the details stand out more, and the whole setup exudes a real sense of solidity.

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 is more than just an accessory; it's an integral part of the system's overall quality. Made of marine plywood , it's designed to withstand humidity and the specific demands of a reef environment. Adjustable feet make leveling easy, which is essential for an aquarium of this size. Like the REEFER 525 and larger models, this cabinet also features aluminum front reinforcements , a real plus for the overall rigidity of the structure. The visual appeal is very clean, with an elegant white finish that blends seamlessly into a modern interior. The whole setup inspires confidence and immediately gives the impression of high-quality equipment, built to last.

Optimized overflow and quieter water flow: a more pleasant aquarium for everyday use

For a marine aquarium installed in a living room, acoustic comfort quickly becomes an important factor. 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 that are easy to clean. 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 feeling of a cleaner, better-designed, and more comfortable system for everyday use.

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.

A RED SEA aquarium designed for enthusiasts who want a high-end, upgradeable base.
