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 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 525 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 reinforced eurobracing provides additional strength and a refined finish for larger reef systems.
Display Tank Dimensions: 150.1 cm (L) x 59.9 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, stainless steel hinges, and reinforced aluminum supports for added structural integrity. 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 1200 Fleece Roller Filter
- REEFER DC 600 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.
