REEFER 170 G3 in White

REEFER 170 G3 in White – Compact Brilliance for Modern Reef Spaces

The REEFER 170 G3 in White from Red Sea Aquariums brings precision engineering and clean design into one compact system. Built under the trusted REEFER line and found in our Aquariums collection, this model stands out for its simplicity, performance, and understated elegance. Its white marine-spec cabinet adds a bright, contemporary touch that fits seamlessly into homes, studios, or offices.

A New Standard of Style and Strength

Red Sea took what reef hobbyists loved about previous models and refined it with precision. The REEFER 170 G3 in White uses ultra-clear, beveled glass for a crisp view of every coral and detail. The open-top, rimless layout creates a clean silhouette while the hidden overflow box keeps your focus on the display—where it belongs. This design feels modern and purposeful, built to highlight your aquascape rather than distract from it. The soft white finish reflects light beautifully, making the tank appear even larger than its 33.8-gallon display suggests.

Practical Engineering That Makes Reefing Effortless

Every part of the REEFER 170 G3 in White is engineered for quiet, steady operation. The included ReefGate flow valve lets you fine-tune water movement until the system runs nearly silent. The ReefATO+ Auto Top-Off System automatically handles evaporation, temperature tracking, and leak detection, freeing you to enjoy your tank instead of managing it.

Highlights:

• 33.8-gallon rimless display with ultra-clear glass

• 9.8-gallon sump designed for easy customization

• ReefGate flow valve for precise water control

• ReefATO+ auto top-off system with app monitoring

• Compatible with ReefMat 250 and REEFER DC 300 skimmer

• Available in black or white finishes

Built to Last – The Marine-Spec Cabinet

The stand is more than support—it’s a statement piece. Made from laminated, marine-grade plywood, it’s moisture-resistant and built to endure. The cabinet follows the exact contour of the tank, creating a seamless profile that looks tailored rather than assembled. Leveling feet make setup simple, and stainless hinges resist corrosion even in saltwater conditions.

Designed for Customization and Quiet Confidence

The sump layout offers flexibility for hobbyists who like to grow with their systems. You can integrate a ReefMat fleece roller for automated filtration or upgrade to a REEFER DC protein skimmer as your coral collection expands. Every connection comes pre-glued and ready for installation—no messy adhesives or complicated plumbing sessions.
