REEFER G3+ systems come with elegant jet-black eurobracing, ultra-clear glass bonded with high-quality euro-silicone, a high-precision gate valve, hydrodynamically superior piping, and are fully supported by reinforced marine-spec cabinets. They also include the advanced ReefControl ATO module, the base for all your aquarium monitoring needs. REEFER G3+ systems come with an extended warranty of up to 5 years.
Bring a reef into the centre of your room with a 96 cm Peninsula display, designed to be enjoyed from both long sides. The Red Sea REEFER Peninsula 350 G3+ combines a 278 litre display with an in-cabinet sump, providing a manufacturer-rated total system water volume of 352 litres. Its 96 x 63.5 x 60 cm display gives you a defined space to plan rockwork, coral placement and swimming areas. As part of the G3+ range, it brings together the aquarium, cabinet, sump, plumbing and automatic top-up controls in a reef-ready foundation that you can equip to suit your reef.
Ultra-clear glass provides a clear view of your aquascape, with 15 mm front glass and 15 mm side glass. High-quality euro-silicone is used to bond the glass. The marine-spec plywood cabinet has laminated panels, epoxy-painted doors, stainless-steel hinges and adjustable levelling feet. These features combine a finished furniture appearance with access to the sump below.
The G3+ water-management design uses hydrodynamic piping and the ReefGate precision gate valve. Adjusting the downflow through the valve helps you balance the drain against your chosen return pump and reduce operating noise. The enlarged downflow inlet is designed to reduce turbulence, while the removable surface-skimming combs make the overflow easier to clean. This model has two 25 mm return outlets and supports single- or dual-pump plumbing configurations. Side-mounted returns direct water along the Peninsula display, helping distribute the returning flow towards the far end of the aquarium.
The in-cabinet sump places filtration equipment below the display. Its adjustable-height skimmer chamber lets you set the operating water depth to suit the requirements of your chosen protein skimmer. The mechanical filtration section includes one filter sock and one media cup. The removable mechanical filtration compartment makes the sump ReefMat-ready, so you can add a compatible automatic roller filter as an upgrade. A refugium-ready layout also gives you the option to incorporate a refugium into your filtration plan.
ReefControl Lite and the ATO Module are included. Automatic freshwater top-up replaces water lost through evaporation, helping maintain the system water level and salinity, while integrated temperature monitoring supports day-to-day checks. The Lite controller supports up to two ReefSense probes or sensors and one 12 V DC device. You can expand monitoring and control with optional compatible ReefSense devices and ReefControl Power as your setup develops.
The Peninsula layout presents the reef through both long viewing panels, making it suitable as a room divider or freestanding focal point. Cabinet doors can be fitted on the left or right to suit the room layout and provide practical sump access.
