REEFER™ XL + 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 vented space for chillers, is smartly finished with weatherproof, epoxy-painted doors. Offered with black or white exteriors, all cabinets have a black interior which maintains its clean appearance over time.


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.
