The new REEFER™ XL 425 is 3" wider than the regular REEFER™ 350 & 450, enabling you to create substantial aquascaping while still providing plenty of water volume and space for your aquarium inhabitants. Both also feature proportionately larger sumps with an extra 1.2" water height in the skimmer chamber.

Red Sea’s REEFER™ series of Reef Systems provide advanced hobbyists with a solid foundation for building a fully featured reef or marine aquarium. They 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 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. The water management system features 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.

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.

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.
