Red Sea MAX NANO G2 XXL – 53 Gallon Complete Reef System

Go bigger without giving up the convenience of an all-in-one reef aquarium.

The Red Sea MAX NANO G2 XXL brings the simplicity of Red Sea's MAX NANO platform to a spacious 53-gallon complete reef system, combining premium ultra-clear glass, integrated rear filtration, protein skimming, powerful circulation, and dual ReefLED lighting into one clean, coordinated aquarium.

Paired with the elegant White Red Sea cabinet, the MAX NANO G2 XXL creates a complete reef display measuring just over 35 inches wide while offering substantially more room for aquascaping, fish, and coral than a traditional nano aquarium.

Complete Plug & Play Reef System

The MAX NANO G2 XXL is designed to eliminate the process of individually selecting and matching many of the major components required to build a reef aquarium.

The system incorporates reef lighting, circulation, protein skimming, mechanical filtration, chemical media capacity, and an integrated rear sump into a coordinated platform built around Red Sea's REEF-SPEC principles.

Dual ReefLED Lighting

The MAX NANO G2 XXL includes two Red Sea ReefLED G2 60 fixtures, providing powerful reef-specific lighting across the 35.4-inch display.

The ReefLED G2 60 can be tuned from a 10,000K reef-white appearance to a 23,000K REEF-SPEC blue, giving reef keepers control over the appearance of their aquarium while providing lighting designed for coral growth and coloration.

Integrated Protein Skimmer

Hidden within the rear filtration compartment is the MSK900 protein skimmer, providing integrated removal of dissolved organic waste without requiring a separate external sump.

The rear filtration system keeps the equipment hidden behind a rotatable screen, maintaining the clean appearance of the display while keeping equipment accessible for maintenance.

Powerful Dual Circulation

Two Sicce 410 GPH circulation pumps provide approximately 10x system-volume circulation through the integrated filtration system.

Filtered water returns through two multidirectional adjustable nozzles, allowing flow to be directed throughout the aquarium and helping minimize stagnant areas within the display.

Ultra-Clear Rimless Display

The MAX NANO G2 XXL uses 12 mm / 0.47-inch ultra-clear glass with a rimless design for an unobstructed view of the reef.

At approximately 35.4" × 21.7" × 19.7", the display provides a broad footprint for aquascaping while retaining the compact proportions that make all-in-one systems attractive.

NanoMat & ReefATO+ Ready

Want to automate it further? The rear filtration system is designed to accommodate two major Red Sea upgrades:

Red Sea NanoMat – adds automatic fleece roller mechanical filtration.

Red Sea ReefATO+ – adds automatic top-off functionality along with temperature monitoring and leak detection.

Both are optional and sold separately.

Integrated Rear Filtration

The rear sump includes a removable surface skimmer, 225-micron filter bag, MSK900 protein skimmer, dedicated media chamber, bubble traps, dual circulation pumps, and adjustable return nozzles.

Red Sea also includes 100 grams of REEF-SPEC carbon, enough for approximately the first two months according to the retailer's product specifications.

White Marine-Spec Cabinet

This package includes the White cabinet, designed to complement the clean, rimless appearance of the MAX NANO G2 XXL.

Red Sea describes the cabinet as marine-spec plywood with weather-resistant epoxy-painted doors, push-open hardware, and soft-close stainless-steel hinges.
