Meet the Next Generation: The All-New Red Sea REEFER G3 Aquarium is Smarter, Stronger, and Quieter
Red Sea’s REEFER G3 series represents the next evolution of premium reef-ready aquariums, bringing quieter operation, stronger construction, and more efficient flow to saltwater hobbyists around the world. Designed for reef keepers who want both beauty and performance, the G3 lineup delivers a professional-grade foundation that’s easy to customize for any level of reefing.
Smarter Flow and Quieter Performance
The REEFER G3 aquariums now feature completely redesigned plumbing that reduces the number of sharp 90-degree bends, improving circulation and lowering noise. With up to 50% more water flow, these upgrades maximize pump efficiency and create a calmer, more natural environment for your corals and fish. The new ReefGate flow valve allows for precise control over the drain rate, helping achieve near-silent operation while maintaining ideal water levels in the overflow.
Upgraded Equipment and Built-In Innovation
Each REEFER G3 system comes with the Red Sea ReefATO+, a smart auto top-off system that monitors and maintains stable water levels automatically. Larger models are compatible with the ReefMat, Red Sea’s innovative automatic filter roller that keeps the water crystal clear with minimal maintenance. Together, these upgrades make the G3 one of the most convenient and self-sustaining reef aquarium systems ever offered by Red Sea.
Sizes for Every Space and Style
The G3 familyincludes a variety of configurations to suit any setup: the standard REEFER G3, the larger REEFER-S G3 systems with enhanced support and sump space, and the Peninsula G3, designed for open-concept viewing from multiple angles. Ranging from 4 to 7 feet (120–210 cm), there’s a model perfectly suited for every level of reef keeper — from ambitious hobbyists to seasoned pros.
Built for Reefers, by Reefers
With stronger Euro-braced glass on models 425 G3 and above, aluminum framing, improved sump design, and refined plumbing, the REEFER G3 is engineered for reliability and long-term stability. Combined with Red Sea’s attention to detail and modern styling, it’s clear that the REEFER G3 isn’t just an upgrade — it’s a complete re-thinking of what a reef aquarium system can be.
