Product Overview

The Red Sea REEFER G3+ 700 Peninsula Aquarium and Cabinet is designed for marine aquarists who want the freedom to create their own premium reef system.

Unlike conventional aquariums viewed primarily from the front, the peninsula design allows the reef to be enjoyed from both long sides and the end viewing panel. This makes it an excellent choice for positioning between living spaces, in open-plan rooms or as a spectacular standalone aquarium display.

The REEFER G3+ platform combines reinforced construction, modern filtration technology and integrated monitoring while allowing aquarists to select their preferred lighting, water circulation, skimming and return pump equipment.

Premium Peninsula Aquarium Design

The REEFER G3+ 700 Peninsula offers an impressive 151cm-long viewing area, creating excellent opportunities for natural reef aquascaping.

Its wider 68cm footprint gives aquarists the space to create open swimming areas, branching coral structures, live rock islands and dramatic reef formations.

The three-sided viewing arrangement allows the aquarium to act as a visual centrepiece, with the overflow and plumbing positioned at one end of the system.

The ultra-clear glass helps showcase marine livestock, coral fluorescence and natural reef colours with excellent clarity.

Aquarium and Cabinet Construction

The REEFER Peninsula S-700 G3+ features 19mm glass construction with reinforced Euro-bracing for additional structural support.

The premium cabinet incorporates a marine-specification aluminium superstructure and durable cabinetry designed to support the substantial weight of a fully stocked marine aquarium.

The cabinet provides access to the filtration sump, aquarium plumbing and technical equipment, while the included slide-out control panel allows controllers and electrical equipment to be organised neatly.

Adjustable cabinet feet help achieve accurate levelling during installation.

Advanced REEF-SPEC Filtration Sump

The Red Sea REEFER G3+ 700 Peninsula includes a professional filtration sump designed for flexibility, accessibility and efficient water management.

The sump includes a mechanical filtration section with filter socks and media cups, together with a removable chamber that allows installation of a compatible Red Sea ReefMat automatic roller filter.

A refugium-ready configuration allows aquarists to incorporate macroalgae filtration or additional biological filtration where required.

The adjustable-height skimmer chamber helps accommodate different protein skimmers and allows the operating water level to be tailored to the equipment being used.

Integrated ReefControl Monitoring

The REEFER G3+ 700 Peninsula includes Red Sea's ReefControl Pro system with an automatic top-up module and integrated temperature monitoring.

The automatic top-up function helps maintain the aquarium's water level by replacing evaporated freshwater, supporting stable salinity in the marine aquarium.

ReefControl provides a foundation for monitoring and expanding aquarium automation using compatible Red Sea equipment and sensors.

Additional ReefSense probes, monitoring accessories and control equipment can be added separately where supported.

Precision Water Management

Red Sea's advanced water-management system is designed to deliver efficient circulation between the display aquarium and filtration sump.

The precision overflow valve allows the water flow to be adjusted for smooth, quiet operation.

Dual 25mm return outlets provide flexibility when selecting a single or dual return pump configuration.

The system is designed to support reliable aquarium operation while giving aquarists flexibility when choosing their preferred return pump and filtration equipment.
