    The REEFER-S models come with the unique split-sump system.
    The main sump is refugium-ready, and has an adjustable-height skimmer chamber, micron filter bags and media cups.

    The extension sump can be used for a dedicated frag tank, a larger refugium, or simply for extra filtration.

    Alternatively, the extension sump can be disconnected from the main sump, and used as a R/O reservoir or for saltwater changes.


    REEFER-S G2+ systems have a removable, ReefMat-ready mechanical filtration compartment, complete with micron filter socks and media cups.

          The REEFER-S G2+ Deluxe incorporates the ReefLED 160S lighting units with Red Sea’s custom mounting system into these reef-ready systems in a convenient single package.
          At the heart of the ReefLED is a compact Led array that provides a reef-safe range of REEF-SPEC light through a single REEF-SPEC Blue (23,000 Kelvin) channel that consists of an optimum combination of ultraviolet, violet and blue LEDs and an 9,000 Kelvin white channel.
          In addition, it has a separate dedicated 3W Moonlight channel to provide the low levels of light for reef-safe nighttime viewing.
          The ReefLED 160S combines 160W of REEF-SPEC & Reef-Safe LED light with a patent-pending stadium-shaped lens, creating a beautiful, homogeneous spread throughout an aquarium of 80cm / 32’’ in all three directions.

          ReefLED is 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, and a lunar cycle for the moonlights.
          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™ Peninsula Deluxe comes with a customized hanging system for the ReefLED lights.
