What’s new in the Red Sea REEFER G3+ XL 425

ReefControl Pro: an included smart controller

The REEFER G3+ XL 425 comes with ReefControl Pro, a smart solution that centralizes the management of certain aquarium equipment.

This new generation replaces the previous standalone top-off management with a single controller, capable of supporting the new Reef ATO system and accommodating up to 7 ReefSense probes and sensors as well as 2 x 12 V devices.

ReefControl Pro works with the Red Sea ReefBeat app, allowing you to view available information and manage compatible functions from a smartphone.

Reef ATO for ReefControl: integrated automatic top-off

The new Reef ATO for ReefControl replaces the ReefATO+ found on previous generations.

This device automatically compensates for water evaporation in the aquarium by adding purified water when needed.

Thanks to its direct connection to the ReefControl Pro controller, the system provides centralized top-off management without requiring a separate dedicated controller.

A scalable system with ReefSense sensors

The ReefControl Pro is designed to support the evolution of the reef setup.

It allows for the later addition of compatible ReefSense digital probes and sensors to expand the aquarium’s monitoring capabilities.

Depending on the accessories installed, the user can access measurements, view available history, and receive notifications through the connected Red Sea ecosystem.

Jet-Black trim and high-quality European silicone

The REEFER G3+ XL 425 features a new Jet-Black internal trim, giving the aquarium a modern and elegant finish.

This finish is paired with high-quality European silicone, selected to meet Red Sea’s aquarium manufacturing standards.

Technical specifications of the REEFER G3+ XL 425

Aquarium dimensions and water volumes

The REEFER G3+ XL 425 is 120 cm long and 60 cm deep, providing an excellent footprint for creating a balanced, structured, and open reefscape.

Its 55 cm height makes aquascaping and coral viewing easier. The total height of the setup with cabinet reaches 142 cm, excluding lighting.

Optimized and quiet water circulation

Improved hydrodynamic design

The REEFER G3+ XL 425 benefits from the improved hydraulic system developed for Red Sea’s G3 generation.

The plumbing has been redesigned to reduce head loss and improve circulation between the aquarium and its sump. According to Red Sea, this design can provide up to 50% more circulation in comparable setups.

ReefGate valve and optimized overflow

The high-precision ReefGate valve allows fine adjustment of the drain flow to the sump in order to reduce water noise.

The overflow system also features a removable surface intake for easier maintenance, as well as curved return nozzles that help distribute water more effectively.

A scalable ReefMat-ready sump

The 90 L sump of the Red Sea REEFER G3+ XL 425 makes it possible to group together the main technical equipment required for a reef aquarium.

It includes a removable mechanical filtration section, allowing a compatible Red Sea ReefMat automatic filter to be installed later.

The system also allows for the installation of a skimmer and other filtration accessories suited to the aquarium’s volume.

This design makes maintenance easier, improves equipment organization, and allows the setup to evolve gradually.

A sturdy cabinet and ultra-clear glass aquarium

The REEFER G3+ XL 425 features ultra-clear glass panels that offer excellent transparency and especially enhance the natural colors of corals and marine fish.

The cabinet is built on a robust laminated marine plywood structure, with adjustable feet for precise leveling.

Its epoxy-finished doors and stainless-steel hinges are designed to meet the demands of marine aquarium use.

The cabinet is available in black or white to blend harmoniously with different interior styles.

Available options for the REEFER G3+ XL 425

The Red Sea REEFER G3+ XL 425 is offered in six configurations, allowing you to choose the cabinet color and whether or not LED lighting is included.

REEFER XL 425 with black cabinet

The REEFER G3+ XL 425 black cabinet version combines a 433 L reef aquarium with an elegant black cabinet. This configuration is ideal for aquarists who want to freely choose their lighting and additional equipment.

REEFER XL 425 with white cabinet

The REEFER G3+ XL 425 white cabinet version offers the same technical features with a modern, bright white cabinet. It allows the aquarium equipment to be fully customized according to the needs of the setup.

REEFER XL 425 Deluxe with 2 ReefLED 115s

The REEFER G3+ XL 425 Deluxe versions with black or white cabinet include two Red Sea ReefLED 115 light fixtures, along with their suitable mounting system.

This configuration provides LED lighting designed for reef aquariums, with settings accessible through the ReefBeat app.

REEFER XL 425 Deluxe with 2 ReefLED 170s

For more demanding reefs, the Deluxe versions with two ReefLED 170s and black or white cabinet provide higher light output, ideal for SPS corals placed higher up.

Why choose a Deluxe version with ReefLED?

The REEFER G3+ XL 425 Deluxe versions provide a Red Sea lighting system specifically designed for reef aquariums right out of the box.

The ReefLED lights are designed to promote coral growth while enhancing their fluorescent pigments. Two units make it possible to evenly light a 120 cm aquarium.

Compatible with the ReefBeat app, they allow you to customize lighting schedules and program smooth transitions between the different phases of the day.

The standard versions, on the other hand, are an excellent solution for aquarists who want to use their own lighting equipment.

An aquarium suited to marine fish and corals

The REEFER G3+ XL 425 offers generous volume for creating a reef aquarium with soft corals, LPS corals, or SPS corals, provided suitable equipment is used.

Its 60 cm depth and 120 cm length make it possible to create rock structures with multiple levels and varied coral placement zones.

With a 120 cm front panel, it is suitable for a fine selection of small to medium-sized marine fish, taking into account their behavior, needs, and compatibility.

Why choose the Red Sea REEFER G3+ XL 425?

The Red Sea REEFER G3+ XL 425 combines the hydraulic performance of the G3 generation with the new smart management possibilities offered by ReefControl Pro.

Its integrated automatic top-off system, ReefMat-ready sump, ultra-clear glass, and sturdy cabinet make it an ideal base for creating an elegant and scalable marine aquarium.

Available with a black or white cabinet, in standard or Deluxe with 2 ReefLED 115s or 2 ReefLED 170s versions, it suits both custom reef projects and setups looking for a Red Sea lighting solution integrated from the start.
