Red Sea Reefer G3+ 950 Max Peninsula Aquarium and Cabinet

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.

Make a large reef the centrepiece of your room with a 200 cm Peninsula display, two long viewing sides and a flexible split sump. The Red Sea REEFER MAX Peninsula S-950 G3+ combines a 757 litre display with an in-cabinet sump, providing a manufacturer-rated total system water volume of 947 litres. Its 200 x 68 x 65 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 with a matched package of lighting, filtration and circulation equipment.

Ultra-clear glass provides a clear view of your aquascape, with 19 mm front glass and 19 mm side glass. Jet-black glass eurobracing reinforces the upper perimeter of the aquarium for extra structural strength. High-quality euro-silicone bonds the glass for long-lasting structural integrity. Additional bottom bracing further reinforces the tank base. The cabinet uses a marine-spec anodised aluminium frame with replaceable exterior panels and concealed adjustable feet. A slide-out control panel provides an accessible mounting area for controllers and other equipment, helping you organise the hardware beneath the display.

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 two filter socks and two media cups. The removable mechanical filtration compartment makes the sump ReefMat-ready, and the MAX package includes a ReefMat 1200 automatic roller filter. A refugium-ready layout also gives you the option to incorporate a refugium into your filtration plan. The split-sump extension offers further flexibility: use it for a refugium, frag tank or extra filtration, or disconnect it for use as an RO reservoir or for water changes.

ReefControl Pro, the ATO Module and a ReefSense pH/temperature probe are included. Automatic freshwater top-up replaces evaporation losses, helping maintain water level and salinity. The probe monitors pH and temperature, while the Pro controller supports up to seven ReefSense probes or sensors and two 12 V DC devices. Optional compatible sensors and ReefControl Power can expand the system.

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.

The MAX version combines the aquarium, cabinet, sump and plumbing with ReefLED G2 lighting and mounts, a ReefRun G2 return pump, ReefWave circulation, a REEFER DC skimmer, a ReefMat roller filter and ReefControl Pro monitoring with automatic top-up. The equipment specifications below identify the models and quantities supplied with this aquarium.

he matched MAX package adds smart equipment to the G3+ aquarium foundation. Lighting, mechanical filtration, protein skimming and water movement work together, with ReefBeat providing control of compatible connected devices.

ReefLED G2 lighting provides adjustable reef lighting with acclimation settings, scheduled operation and a dedicated moonlight channel. A customised hanging system supports the lights over the Peninsula display. The variable-speed ReefRun G2 pump returns water from the sump, while ReefWave pumps provide broad circulation within the display. ReefBeat settings let you tailor compatible devices to the needs of your reef.

The ReefMat roller filter automatically advances its fleece as it collects suspended waste, reducing routine sock-cleaning work. The REEFER DC skimmer removes dissolved organic waste and uses self-levelling technology to help prevent over-skimming and collection-cup overflow. ReefControl Pro combines automatic top-up with the included pH/temperature probe, bringing everyday monitoring into the equipment package.
