Red Sea MAX NANO G2 XL – 33 Gallon Complete Reef System

Bring the performance of a full reef system into a compact footprint with the Red Sea MAX NANO G2 XL.

With 33 gallons of total system volume, the MAX NANO G2 XL combines an ultra-clear rimless aquarium, integrated rear filtration, protein skimmer, circulation pump, automatic top-off reservoir, and ReefLED lighting into a coordinated plug-and-play reef system.

This package includes the matching Black marine-spec cabinet for a clean, modern installation.

Complete Plug & Play Reef Aquarium

The MAX NANO G2 XL is designed to take the guesswork out of selecting compatible reef equipment.

Major filtration, circulation, and lighting components are integrated into the system, giving both new and experienced reef keepers a complete foundation for building a coral aquarium without the complexity of designing a traditional sump-based system.

ReefLED 50 Lighting

Included with the system is Red Sea's 50W ReefLED 50, designed specifically around the lighting requirements of reef-building corals.

The fixture combines Red Sea's REEF-SPEC Blue channel, a 9,000K white channel, and a dedicated 3W moonlight channel.

Control is available through the ReefBeat app, including lighting schedules, acclimation, random cloud effects, and lunar-cycle moonlight programming.

Integrated Rear Filtration

All major filtration equipment is hidden within the rear sump, keeping the display clean while maintaining easy access for maintenance.

The filtration system includes a removable surface skimmer, 225-micron filter sock, NANO XL protein skimmer, media chamber with 100g of REEF-SPEC carbon, bubble trap, and return circulation system.

410 GPH Circulation

A Sicce 410 GPH / 1,550 LPH circulation pump moves water through the rear filtration system and returns it to the aquarium through an adjustable multidirectional nozzle.

A built-in pump power center provides conveniently located controls for the circulation pump and skimmer during feeding and maintenance.

NanoMat & ReefATO+ Ready

The MAX NANO G2 XL can grow with your reef.

Its rear filtration system is NanoMat ready, allowing the standard mechanical filtration to be upgraded to Red Sea's compact automatic fleece roller.

The system is also ReefATO+ ready, allowing you to upgrade to Red Sea's smart automatic top-off, temperature monitoring, and leak detection platform.

NanoMat and ReefATO+ are optional and sold separately.

Integrated Automatic Top-Off

An automatic top-off system with an integrated RO reservoir is already included with the aquarium, helping maintain a stable water level as freshwater evaporates.

Customers who want additional smart functionality can upgrade to the optional ReefATO+ system.

Deep, Wide Reef Display

The XL uses a deep footprint that provides substantial front-to-back aquascaping room for a 33-gallon system.

Total System Volume: 33 gallons / 125 L
Display Volume: 29 gallons / 110 L
Aquarium: 19.7" L × 23.6" W × 19.7" H
Total System Height: 54" excluding light

That 23.6-inch depth gives reef keepers plenty of room to build layered rock structures, coral islands, and open swimming areas without moving to a large aquarium.

Black Marine-Spec Cabinet

This package includes the matching Black cabinet, featuring marine-spec construction, weather-resistant epoxy-painted doors, push-open hardware, and soft-close stainless-steel hinges.
