Red Sea REEFER G2+ XL 300 Black Deluxe Aquarium System

If we do not have one in stock, we are happy to order one in specially for you.

Designed as the perfect reefscaping canvas, REEFER G2+ tanks combine REEF-SPEC infrastructure with the freedom to install all your preferred hardware.

REEFER G2+ systems come with new & improved water management, extra-fortified cabinets & aquariums, REEF-SPEC ReefMat-ready sumps, include the ReefATO+ system as standard and a 5-year extended warranty.

REEFER G2+ SYSTEMS come in a huge variety of sizes (from 170 L / 45 gal to 1000 L / 264 gal), and are the ideal platform for the full “Red Sea Experience”, combining our LED lighting, wave pumps, dosers, and filtration devices into one smart, synchronized eco-system operated via the ReefBeat App.


 Rimless ultra-clear glass

    REEFER G2+ aquariums are rimless, and constructed from ultra-clear, beveled-edge glass with increased thickness of up to 19 mm or 0.75”.

    Extra fortified plywood cabinet

      The marine-spec laminated cabinets follow the contour of the glass, and are now all fortified and made of plywood. The “floating tank” feature is now reinforced with front aluminum supports on all REEFER 625 G2+ models and bigger.

      Dual return pump outlets

      All REEFER 350 G2+ models and bigger now have dual side-facing return pump outlets, creating an even better water distribution.

      Surface skimmer

        The piping is hidden inside a large central overflow box, which has a large surface skimmer with removable comb parts, for easy cleaning.

        Silent downflow system

          The enlarged rectangular inlet to the downflow pipe (on models up to REEFER 625) reduces turbulence, making it easier to regulate.

          Assembly-ready piping

          All pipes are preformed with quick connectors at all joints (no gluing required). Bulkhead connectors suitable for both Metric and USA standard pipes can be purchased separately, allowing you to customize your sump piping.

          High precision valve

            All models now have a new and improved high precision valve on the downflow pipe, allowing for easy regulation of the flow and a near silent operation.

            Professional REEF-SPEC sump

              The professional sump includes a removable mechanical filtration media compartment (with micron filters & filter cups), an optional refugium compartment, an adjustable height skimmer chamber for optimal skimmer performance, and a bubble trap to prevent air bubbles from returning to the aquarium.


                The easily removable mechanical filtration compartment allows for a quick Plug & Play installation of the ReefMat 500/1200.


                  All REEFER G2+ models come with the state-of-the-art ReefATO+, which keeps your water volume and salinity stable, and includes an accurate temperature monitor as well as a highly sensitive leak detector. *Reservoir not included.

                  Chiller & hardware chamber

                    Most models come with an additional chamber that can be used for a chiller, controllers and other equipment.


                    To ensure a constant water level in the pump compartment, all REEFER sumps include an integrated automatic freshwater top-up unit, guaranteeing a constant, stable water flow throughout the complete system.
                    Supplied as a complete self-assembly kit, all pipe work is ready without the need for any gluing.
