Unmatched water circulation & surface skimming
Maintaining the familiar rimless format and clean lines of the REEFER series, the 3XL 900 introduces an enlarged overflow box with dual side-facing return pump outlets and increased surface skimming that provides ideal water circulation in the tanks with flows of up to 10,000 lph / 2600 gph. The new dual return system and the enlarged overflow developed for the 3XL 900 have also been implemented on the XXL 750 V3, giving it a new look and significantly improved flow dynamics and surface skimming. Both systems come complete with fittings to attach either single or dual return pumps.
The new split sump - unsurpassed flexibility
A unique feature of the 3XL 900 is a split sump system that provides unmatched 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 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 RO reservoir or saltwater reservoir for automated water changes.
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.
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.
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.
