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 designed for hobbyists who want a premium rimless aquarium with the flexibility to choose their own filtration, lighting, and equipment.
Each system provides a strong, reef-ready foundation with smart features and a clean, modern design.
The REEFER 300 G3 Aquarium
Constructed from ultra-clear, beveled-edge glass for distortion-free viewing. A low-profile overflow box and concealed plumbing keep the display clean, while the rimless design enhances the overall aesthetic.
Display Tank Dimensions: 89.9 cm (L) x 57.4 cm (W) x 55.1 cm (H)
REEFER Marine-Spec Cabinet
The laminated marine-spec cabinet is constructed from plywood for strength and moisture resistance. It includes leveling feet and stainless steel hinges for long-term durability. Available in black or white finishes.
Reef-Ready Sump
The included glass sump features a clean and flexible layout compatible with a wide range of filtration equipment, including:
- ReefMat 500 Fleece Roller Filter
- REEFER DC 300 Protein Skimmer
(Sold separately)
Ready-to-Use Plumbing
All plumbing is pre-assembled for quick installation with no gluing required. The updated design reduces flow resistance, and the ReefGate valve allows precise and quiet adjustment of water flow.
ReefATO+ Auto Top Off System
The included ReefATO+ combines multiple critical functions into one system:
- Automatic Top Off: Dual-sensor system with built-in backup protection
- Temperature Monitoring: Pre-calibrated sensor with ±0.1°C accuracy
- Leak Detection: Titanium probes detect both saltwater and RO/DI leaks
Integrated with the ReefBeat app for real-time monitoring and alerts.
