Red Sea’s REEFER™ series of Reef Systems, provide advanced hobbyists with a solid foundation for building a fully featured reef or marine aquarium.


The REEFER™ series combines a contemporary, rimless, ultra-clear glass aquarium with a stylish cabinet and a comprehensive water management system, including a professional sump with integrated automatic top-up, and Red Sea’s unique silent down-flow system. Incorporating technologies originally developed for Red Sea’s all-in-one MAX® coral reef systems, the REEFER™ series is designed for ease of operation while enabling the advanced hobbyist to install an unlimited choice of lighting, filtration, circulation and controllers to create a uniquely customized system.


Features of the Red Sea REEFER™ include:
  • Rimless, ultra-clear, beveled edge glass aquarium
  • Elegant marine-spec cabinet
  • Professional sump with constant height skimmer chamber and micron filter bags
  • Silent, regulated down-flow system with emergency overflow
  • Integrated automatic top-up system with reservoir
  • Assembly-ready piping – no gluing required

REEFER™ Specification

REEFER™ aquariums are constructed from thick, beveled-edge, ultra-clear glass to support their elegant and modern rimless design. The aquarium sits on a recessed base that “floats” it above the cabinet, which seamlessly follows the contour of the glass.The marine-spec laminated cabinet that houses the sump, (and in the larger models also includes a dedicated, vented space for chillers) is smartly finished with weatherproof, epoxy-painted doors.      


REEFER™ Water Management System

Removable surface-skimming combs surround the top of the centrally located overflow box that houses the downpipe, sump return pipe and the discreet multi-directional “eyeball” return outlet nozzle.   In the event of a blockage in the regulated downpipe, an additional emergency overflow pipe provides an unrestricted free flow of aquarium water directly to the sump.       


On entering the sump the water passes through a 200 micron mechanical filter bag, before entering the filtration compartment that maintains a constant water height, making it suitable for all skimmers and other reactors. In order to remove any air bubbles that may have escaped from the skimmer, the water passes through a bubble-stripping cascade on its way to the return pump chamber.      


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.
