Red Sea REEFER™ Systems
Rimless reef ready systems for advanced hobbyists
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 refugium ready sump with integrated automatic top-up and Red Sea’s unique silent down-flow system.
The REEFER™ 3XL 900 allows you to take reefscaping to another dimension. The 3XL 900 is 65cm (25.6?) high & wide, and 200cm (79?) long with a 900 liter (240 gal) capacity. This unit introduces an enlarged overflow box with dual side-facing return pump outlets that provides ideal water circulation in the tanks with flows of up to 10,000 lph/2600gph.
A unique feature of the 3XL 900 is a split sump system that provides unsurpassed flexibility. The main sump is set for the main filtration functions with an optional refugium chamber and a dedicated adjustable height skimmer chamber. The sump extension (60 liters/16 gal) can be connected to the main sump and used for additional filtration, as a larger refugium, or even as a dedicated frag tank. Alternatively, it can be set up as an independent unit and used as a full-size (83 liters/22 gal) RO reservoir or saltwater reservoir for automated water changes.

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 micron filters and/or filter cups with your choice of media before flowing into the optional refugium and onto the skimmer chamber with an adjustable height outlet, 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.
