Red Sea has been building aquariums for years, delivering high-quality, thoughtfully engineered systems that make reefing easier and more enjoyable. The REEFER G3 series is a top choice for hobbyists who want a premium aquarium with the flexibility to choose their own filtration, lighting, and equipment. Each system offers a strong, reef-ready foundation with smart features and a clean, modern design.
The REEFER 525 G3 Aquarium
Red Sea’s REEFER 525 G3 aquarium uses ultra-clear, beveled-edge glass for vibrant, distortion-free viewing. Every edge and panel is precisely cut and assembled for a clean, modern appearance that looks just as good empty as it does fully stocked. A low-profile black overflow box and hidden plumbing keep the display clean and uncluttered while the reinforced eurobracing along the top provides both peace of mind and a professional finish worthy of a high-end reef system.
Display Tank Dimensions: 59.1"L x 23.6"W x 21.7"H
REEFER Marine-Spec Cabinet
The marine-spec laminated cabinet is made of plywood and precisely follows the contour of the aquarium for a seamless fit. It’s built for strength and moisture resistance, with leveling feet and stainless steel hinges to ensure long-term durability. Stands are available in black or white finishes to complement any space. Reinforced aluminum supports are included for the REEFER 525 models and larger.
Reef-Ready Sump
The included glass sump features a clean, straightforward layout that makes it easy to set up and maintain. Its flexible design is compatible with a wide range of filtration equipment, including Red Sea’s ReefMat fleece roller filters and REEFER DC protein skimmers, giving you plenty of upgrade options as your system grows (ReefMat and REEFER Protein Skimmer are sold separately).
Ready-to-Use Plumbing
REEFER G3 systems include all the plumbing you need, ready for quick assembly with no gluing required. The redesigned G3 layout reduces the number of 90-degree turns for smoother flow, while the new ReefGate flow valve makes it easy to fine-tune your system's drain plumbing so that it runs quietly.
ReefATO+ Auto Top Off System
Each REEFER G3 system includes the ReefATO+, combining top off control, temperature monitoring, and leak detection all in one device connected to the ReefBeat App.
