Red Sea’s REEFER G3’s benefit from a fully redesigned flow system and new hydrodynamically superior piping, delivering up to 50% more water circulation while significantly reducing energy consumption. Models 425 and above now feature euro-bracing for extra strength and durability.

Reinforced ultra-clear glass
REEFER G3s are constructed from ultra-clear glass with increased thickness. REEFER model 425 and above are braced for extra strength, while the smaller models are rimless with smooth, bevelled edges.

Extra fortified plywood cabinet
REEFER aquariums are mounted on marine-spec plywood cabinets with levelling feet, with REEFER 525 models and above further reinforced with front aluminium supports.

Silent downflow system
The enlarged rectangular inlet to the downflow pipe reduces turbulence, resulting in a quieter operation.

Optimized water circulation
REEFER G3s feature a fully redesigned flow system, delivering up to 50% more water circulation. The larger models also have wider return piping and upgraded nozzles to further maximize flow.

High precision gate flow valve
All REEFER G3s benefit from the new ReefGate, high-precision bespoke gate valve on the downflow pipe, allowing for easy regulation of the flow and a near silent operation.

Improved return outlets & overflow box
The central overflow box is fitted with a removable surface skimmer for easy maintenance, and the return outlets on all models have been curved for improved water distribution.

ReefMat-ready
REEFER G3 systems have a removable, ReefMat-ready mechanical filtration compartment, complete with micron filter socks and media cups.

ReefATO+
All REEFER G3 models come with the ReefATO+ system, which keeps your water volume and salinity stable, and includes an accurate temperature monitor as well as a highly sensitive leak detector.

Deluxe Version
The REEFER G3 Deluxe incorporates either the ReefLED G2 115 or ReefLED G2 170 lights, along with their respective custom mounting systems.

At the heart of each ReefLED G2 unit is a compact LED array that delivers a rich, reef-safe spectrum. It can be tuned from a 10,000K reef-white to a 23,000K REEF-SPEC blue, all running at full intensity. The REEF-SPEC blue is augmented with violet, UV, and boosted to 470nm at the high end of the PUR spectrum, and a separate dedicated 3W Moonlight channel provides low levels of light for reef-safe nighttime viewing.

ReefLED G2s are controlled by Red Sea’s ReefBeat App, which provides a wide range of easy to use functions such as random clouds, acclimation for new installations, a lunar cycle for the moonlights, and customized light settings, such as for coral photography or a UV look.

The custom mounting system attaches firmly onto the rear wall of the tank and can be rotated to the upright position during reef scaping or other tank maintenance. The REEFER G3 Peninsula Deluxe comes with a customized hanging system for the ReefLED G2 lights.
