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

red sea reefer marine aquarium system - regulated downflow 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 225 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.
