Stunning Three-Sided Peninsula Design

The REEFER Peninsula 350 G3+ offers the visual impact of a premium peninsula aquarium in a manageable size.

Unlike traditional aquariums placed against a wall, the peninsula design allows viewing from both long sides and one short end.

The overflow system is positioned at the opposite end, creating uninterrupted views of your reef from three sides.

With a 37.8-inch length and generous 25-inch width, the aquarium provides excellent opportunities for creative rockwork, coral islands, and open swimming areas.

Its compact footprint makes it particularly appealing for reefkeepers who want a stunning centerpiece without the space requirements of a larger aquarium.

ReefControl Lite Technology

The Peninsula 350 G3+ includes Red Sea's ReefControl Lite Controller, providing connectivity for compatible ReefSense sensors and 12V DC devices.

Through the ReefBeat ecosystem, compatible equipment and monitoring functions can be managed from your smartphone.

ReefControl Lite offers a smart foundation for aquarium management while retaining a streamlined configuration appropriate for this model.

The included digital ATO module automatically manages freshwater top-off and incorporates an integrated temperature sensor.

Additional compatible monitoring probes and sensors are available separately.

Premium Ultra-Clear Glass & Reinforced Construction

The REEFER Peninsula 350 G3+ features 15mm (0.59") ultra-clear glass bonded using high-quality euro-silicone.

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

The display rests on a reinforced cabinet designed for stability and convenient access to filtration equipment.

Redesigned High-Flow Plumbing

A high-precision gate valve allows fine overflow adjustments, helping maintain quiet operation.
