The REEFER XL includes four models that give you the freedom to create more expansive, intricate, and diverse reefscapes without the constraints of the smaller tanks. All four XL models are 57.5cm (22.6‰Û_) wide and 55 cm (22‰Û_) high (excluding XL 200, which is 53 cm/21‰Û_ high). They differ in length and are available in 4 sizes from 60cm (24‰Û_) long/200 liter (53 gal) capacity up to 150cm (59‰Û_) long/525 liter (140 gal). All the REEFER XL models now feature a laminated, plywood marine-spec cabinet for greater water resistance with adjustable feet for perfect leveling on any surface.

Go Behind The ScenesåÊ

Take a peek behind the scenes and see what goes into crafting a Red Sea aquarium.


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 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 ‰ÛÏeyeball‰۝ return outlet nozzle.

In the event of a blockage in the regulated downpipe, an additional emergency overflow pipe providesåÊan 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 andåÊother reactors.

In order to remove any air bubbles that may have escaped from the skimmer, the wateråÊpasses 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‰ã¢ sumps include an integratedåÊautomatic freshwater top-up unit, åÊguaranteeing constant, stable water flow throughout the complete system.

Supplied as a complete self-assembly kit, all pipework is ready without the need for any gluing.
