REEFER Concept
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.

REEFER Water Management System
The comprehensive water management system provides the base for excellent water quality.

Surface water from all sides of the aquarium is actively fed to the sump through the regulated silent-flow downpipe.

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.

Integrated Automatic Top-up
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.

About Red Sea
Since its inception over 25 years ago, Red Sea's vision has been to create a world in which marine and reef aquariums are the aquariums of choice for all hobbyists. This passion has guided the company throughout its product development and design.

Red Sea is committed to providing complete reef solutions, allowing hobbyists like you, to focus on the beauty of your reef inhabitants rather than worry about water chemistry or the suitability and compatibility of aquarium equipment.

Several significant advances in reef keeping have been made possible due to Red Sea's commitment to research. This ongoing, original research carried out by Red Sea's dedicated team of biologists, chemists and engineers, brings great benefits to hobbyists worldwide.

Red Sea's unique research into the biochemistry of corals and their relationship with the surrounding seawater resulted in the development of the Reef and Marine Care Programs. Highly advanced yet easy to implement, the programs empower hobbyists with the knowledge and materials to understand and control the fascinating environment within their aquarium.

In keeping with the company's objective to make successful reef keeping accessible to a wider audience, from novices to experienced hobbyists, Red Sea developed its ground breaking range of MAX aquarium systems. Fully equipped to support even the most delicate stony (SPS) corals, the MAX systems are designed to blend into any contemporary home environment.

Red Sea's wide range of unique solutions enable you to spend more time enjoying your piece of coral reef, achieving long-term success and stunning results.
