Stunning Three-Sided Peninsula Design

The REEFER MAX Peninsula S-700 G3+ is designed to transform an aquarium into a stunning architectural feature.

Unlike traditional aquariums positioned against a wall, the peninsula design allows clear viewing from both long sides and one short end, making it ideal for separating living spaces while maintaining an open, inviting environment.

The overflow system is positioned at one end of the aquarium, allowing the remaining three sides to provide uninterrupted views of your aquascape, corals, and fish.

This unique layout creates exciting aquascaping opportunities, including dramatic reef islands, open swimming channels, and beautiful coral displays that can be appreciated from multiple angles.

Advanced ReefControl Pro Technology

The G3+ generation introduces Red Sea's ReefControl Pro, bringing aquarium monitoring, automation, and equipment management together in one connected system.

Through the ReefBeat app, compatible Red Sea devices can be monitored and controlled from your smartphone, making everyday aquarium management more convenient.

The included ReefControl Pro system features:

• ReefSense pH and temperature probe

• Digital automatic top-off module with integrated temperature sensor

• Support for up to five additional optional ReefSense probes and sensors

• Connections for two 12V DC devices

• ReefBeat app integration for connected monitoring and control

ReefControl Pro provides a flexible foundation for expanding your aquarium's monitoring and automation capabilities as your reef develops.

Premium Ultra-Clear Glass & Reinforced Construction

The REEFER MAX Peninsula S-700 G3+ features a stunning ultra-clear glass display designed to showcase vibrant fish, corals, and aquascaping with excellent clarity from multiple viewing angles.

Reinforced eurobracing and additional bottom bracing provide structural support for this large-format aquarium.

The aquarium rests on an aluminum-supported cabinet structure with a modern floating appearance, offering both strength and contemporary styling.
