Stunning Three-Sided Peninsula Design

The REEFER MAX Peninsula 500 G3+ is designed to transform an aquarium into a stunning architectural centerpiece.

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.

With nearly 50 inches of display length and a generous 25-inch width, this aquarium offers excellent aquascaping possibilities, including beautiful reef islands, open swimming channels, and coral displays that can be appreciated from multiple angles.

The result is a beautiful reef environment that brings movement, color, and natural beauty into your living space.

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 500 G3+ features a stunning ultra-clear glass display designed to showcase vibrant fish, corals, and aquascaping with excellent clarity from multiple viewing angles.

All four vertical glass panels and the bottom are constructed using 15mm (0.59") glass, bonded with high-quality euro-silicone.

Reinforced eurobracing provides additional structural support while maintaining the aquarium's clean, modern appearance.

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

Redesigned Hydrodynamic Plumbing

The G3+ platform features refined plumbing designed to deliver efficient water movement between the aquarium and sump.

The peninsula configuration incorporates dual return outlets positioned at the overflow end of the display, helping distribute water throughout the aquarium.

A high-precision gate valve allows fine adjustments to the overflow, helping achieve quiet, consistent operation.

Two 25mm return outlets distribute water back into the display, and the plumbing supports either single or dual return-pump configurations for additional flexibility.

Complete Reef-Ready Equipment Package

ReefLED G2 170 Lighting – 2 Included

Two Red Sea ReefLED G2 170 fixtures provide powerful, coral-focused lighting across the peninsula display.

These ReefBeat-compatible fixtures offer adjustable lighting schedules and color settings to support a wide range of reef aquarium environments.

The two-fixture configuration provides excellent coverage across the approximately 49-inch-long aquarium, creating a strong foundation for vibrant coral coloration and growth.

ReefWave 45 Circulation Pumps – 2 Included

Two ReefWave 45 pumps provide broad, cross-flow water circulation throughout the aquarium.

Each pump delivers up to 3,960 GPH, with customizable flow patterns that help promote water movement around rockwork and corals while reducing stagnant areas.

The wide, linear flow is especially beneficial in peninsula aquariums, helping distribute water throughout the elongated display.

ReefRun G2 8000 Return Pump – 1 Included

The efficient DC-powered ReefRun G2 8000 provides adjustable return flow from approximately 1,080 to 2,200 GPH.

Integration with ReefBeat allows convenient control of return flow and coordination with compatible aquarium routines.

The adjustable performance allows reefkeepers to fine-tune circulation between the sump and display aquarium.

ReefMat 1200 Automatic Roller Filter

The ReefMat 1200 automatically advances its filter fleece to remove suspended waste and debris from aquarium water.

This reduces the need for frequent manual filter maintenance while helping maintain consistent mechanical filtration and clearer water.

Its large-capacity design is especially beneficial for reducing routine maintenance on established reef aquariums.

REEFER DC 600 Protein Skimmer

The included REEFER DC 600 efficiently removes dissolved organic waste before it can break down in the aquarium.

Featuring approximately 400 GPH water flow and 195 GPH air flow, the skimmer provides efficient organic waste removal and consistent aeration.

Its self-leveling technology helps maintain stable skimming performance and reduces the risk of excessive skimming and collection-cup overflow.

Integrated Digital Automatic Top-Off

The included digital ATO module automatically replaces evaporated water to help maintain a consistent water level and salinity.

An integrated temperature sensor provides additional monitoring through the ReefControl ecosystem.

Convenient Cabinet & Equipment Management

The modern cabinet combines clean styling with practical access to the sump, filtration equipment, and controls.

An included Slide-Out Control Panel 60 provides an organized mounting location for compatible equipment and keeps electronics easily accessible for adjustments and maintenance.

The cabinet's aluminum support structure provides a stable foundation while maintaining the elegant floating appearance of the REEFER Peninsula series.
