REEFER XL 425 Deluxe Aquarium System (88 GAL) - Red Sea


Red Sea REEFER™ Systems

Red Sea’s REEFER™ series of Reef Aquarium Systems provide advanced hobbyists with a solid foundation for building a fully featured reef or marine aquarium.

This series combines a contemporary, rimless, ultra-clear glass aquarium with a stylish cabinet and a comprehensive water management system including a professional refugium-ready 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™ Deluxe Concept

The REEFER™ Deluxe incorporates the all-new ReefLED™ lighting units with Red Sea’s custom mounting system into the Reefer reef ready systems in a convenient single package. The REEFER XL 425 Deluxe Aquarium System comes with 2 ReefLED™ 90 (180W) units.

All REEFER Deluxe systems now feature Red Sea's new ReefLED lighting which has been designed to ensure optimal coral growth, dramatic coloration and a gentle shimmer throughout the aquarium. Guaranteed to be reef­safe and REEFSPEC®, with unique daylight channels they're also very easy to set up. The built­in Wi-FI connects them directly to the internet, enabling you to control them from your smartphone using Red Sea's ReefBeat® smart aquarium app.

ReefLED also includes an optical-glass, hollow lens that ensures a homogenous light spectrum with ideal PAR values throughout the aquarium, without hotspots or areas with insufficient light for coral growth.

ReefLED is controlled by Red Sea’s ReefBeat app which provides a number of preset lighting programs you can choose from as well as additional features including sunrise/sunset effects, lunar cycle moonlight, random clouds and even an acclimation program for new installations. ReefBeat also provides best-practice guidelines during setup as well as useful notifications to your smartphone, for example, in the event of a power outage.

The custom mounting system attaches firmly onto the rear wall of the tank and can be rotated to the upright position during reefscaping or other tank maintenance.

The larger format REEFER™ XL now includes 2 sizes that give you the freedom to create more expansive, intricate and diverse reefscapes without the constraints of smaller aquariums. These aquariums sit on extra durable HPL coated plywood Marine Spec cabinets for greater water resistance, with fully adjustable feet for perfect leveling on any surface.

Features of the Red Sea REEFER™ include:

  • Rimless, ultra-clear, beveled edge glass aquarium
  • Elegant marine-spec cabinet
  • Reef­Spec ReefLED­90 lighting
  • Professional sump with constant height skimmer chamber and micron filter bags
  • 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 also includes a dedicated, vented space for chillers) is smartly finished with weatherproof, epoxy-painted doors.

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. 

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 constant, stable water flow throughout the complete system. Supplied as a complete self-assembly kit, all pipework is ready without the need for any gluing.

New and improved Refugium-Ready Sumps (except REEFER™ 170)

  • An adjustable-height skimmer chamber, enabling you to set the water level for optimal skimmer performance.
  • A “Refugium Ready” sump with two pre-set positions allows you to decide how much of the sump you want for your skimmer and other reactors and how much as a dedicated refugium chamber.
  • Micron filter bags and filter cups
  • Larger RO liter reservoirs that can be slid aside when necessary for pump maintenance.
  • Down-flow valve conveniently located at the front of the cabinet.
