Red Sea Reefer XL 525 Black 139 Gallon Aquarium Tank Setup

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.

Red Sea REEFER XL Concept

The REEFER range now include 2 sizes of larger format systems give you the freedom to create more expansive, intricate and diverse reefscapes without the constraints of smaller tanks.

The REEFER XL 425 and REEFER™ XL 525 models are both 7.5cm/3″ wider than the regular REEFER™ 350 & 450. Both also feature proportionately larger sumps with an extra 3cm / 1.2″ water height in the skimmer chamber.

Features of the Red Sea REEFER include:

• Rimless, ultra-clear, beveled edge glass aquarium
• Elegant marine-spec cabinet
• Professional sump with constant height skimmer chamber and micron filter bags
• Refugium-ready sump with adjustable height skimmer chamber – on selected models
• Silent, regulated down-flow system with emergency overflow
• Integrated automatic top-up system with reservoir
• Assembly-ready piping – no gluing required

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 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.

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.
