Red Sea Max Nano G2 XXL and Black Cabinet

The Red Sea Max Nano G2 XXL and Black Cabinet is a premium 200 litre / 53 gallon all-in-one reef aquarium and cabinet package designed for aquarists who want the largest MAX NANO G2 display with hidden rear filtration, dual ReefLED lighting, dual return pumps, and a clean black stand.

This XXL system delivers the scale and presence of a larger reef aquarium while keeping the simplicity of an all-in-one rear-sump design. It includes a rimless 12 mm ultra-clear glass aquarium, two ReefLED G2 60 lights, REEF-SPEC rear sump filtration, MAX NANO protein skimming, two 1550 LPH Sicce return pumps, two pump power centers, NanoMat readiness, ReefATO+ upgrade compatibility, and a matching black marine-spec cabinet for a finished high-contrast reef display.

Red Sea MAX NANO G2 XXL Black Reef System

• Largest MAX NANO G2 package: The XXL is the biggest model in the MAX NANO G2 family, built for reef keepers who want more display length and water volume without moving into a traditional plumbed sump system.
• Complete aquarium and cabinet system: This version includes both the XXL aquarium and the matching black cabinet for a coordinated furniture-style installation.
• 53 gallon total system volume: The 200 litre volume gives more stability, more coral capacity, and more livestock planning room than smaller MAX NANO models.
• Dual ReefLED G2 60 lighting: Two app-controlled lights provide broader coverage across the longer 90 cm display.
• Dual return pump circulation: Two 1550 LPH Sicce pumps support strong system turnover and balanced return flow.
• Black cabinet finish: The black cabinet frames the aquarium cleanly and gives the reef a bold, modern, high-contrast appearance.

XXL Rimless Display with Black Cabinet Integration

• 12 mm ultra-clear glass: Red Sea lists the XXL with 12 mm rimless ultra-clear glass for a strong, premium viewing panel with excellent clarity.
• 90 cm display length: The longer format creates room for a more natural reefscape, better horizontal swimming space, and more coral placement zones.
• Large all-in-one presence: The system has the visual impact of a larger reef aquarium while keeping filtration concealed in the rear sump.
• Modern black stand: The matching black cabinet creates a finished installation and visually grounds the aquarium in living rooms, offices, showrooms, and dedicated reef spaces.
• Open-top access: The rimless design provides easy access for aquascaping, feeding, coral placement, and maintenance.
• Hidden equipment profile: The rotatable rear screen conceals filtration and circulation equipment without making service difficult.

Dual ReefLED G2 60 Lighting and ReefBeat Control

• Two included ReefLED G2 60 fixtures: The XXL uses dual ReefLED G2 60 lights for better spread across the wider system.
• REEF-SPEC spectrum: Each light is tunable from 10,000K reef-white to 23,000K REEF-SPEC Blue for coral-focused lighting and viewing preference.
• Enhanced blue output: Violet, ultraviolet, and boosted 470 nm blue wavelengths help produce strong coral fluorescence and colour pop.
• Dedicated moonlight channels: Separate 3W moonlight channels provide low-level nighttime viewing.
• ReefBeat smart control: The app supports lighting schedules, acclimation, lunar cycle, random clouds, staggered sunrise and sunset, and custom manual modes.
• Rotatable arms: The lights can be rotated upward for access to the rear sump and display during maintenance or reefscaping.
• Better coral layout flexibility: Dual lighting makes the XXL more practical for multiple coral islands, mixed reef zones, and longer aquascapes.

REEF-SPEC Rear Sump and Protein Skimming

• Hidden filtration chamber: The rear sump houses filtration and circulation equipment behind the aquarium so the display remains clean and natural-looking.
• Removable surface skimmer: Surface water enters the rear sump to help remove film and keep oxygen exchange and light penetration strong.
• 225 micron filter sock: Mechanical filtration captures suspended debris before water reaches the skimmer and media chamber.
• MAX NANO protein skimmer: The skimmer helps remove dissolved organics and thoroughly oxygenate the aquarium water.
• REEF-SPEC skimmer criteria: Red Sea describes the skimmer as passing the system volume through approximately three times per hour with a 3 to 1 water-to-air ratio.
• Chemical media chamber: A dedicated media area allows the use of carbon or other chemical filtration media for water polishing and targeted filtration.
• Bubble trap and dual returns: The sump path helps reduce microbubbles before water returns to the display through two adjustable nozzles.

Dual Pumps, Power Centers, and Upgrade Readiness

• 2 x 1550 LPH Sicce return pumps: The XXL uses two Sicce pumps for strong circulation through the rear filtration system.
• Two adjustable return nozzles: Dual return outlets allow the aquarist to direct flow across the longer display more effectively.
• Approximately 10x turnover: Red Sea lists the circulation system as moving the tank’s water volume about ten times per hour.
• Two pump power centers: The XXL includes two power centers with convenient control for feeding, maintenance, and service.
• NanoMat ready: The rear sump is designed for optional Red Sea NanoMat automatic fleece-roll filtration.
• ReefATO+ ready: The system can be upgraded with optional ReefATO+ functionality for advanced top-off, temperature monitoring, and leak detection.
• ATO planning required: The automatic top-off reservoir supplied with smaller MAX NANO G2 systems is not included with the XXL.

Application Notes for the XXL Black System

• Flow planning: The dual return pumps provide strong turnover, but additional wavemakers may be useful for higher-flow corals or dense aquascapes.
• Top-off planning: Because the XXL does not include the smaller models’ ATO reservoir, evaporation management should be planned separately.

Setup and Installation Notes

• Assemble the cabinet first: Build and level the black cabinet according to Red Sea’s instructions before placing the aquarium on top.
• Check level support: Confirm the cabinet and aquarium are level before filling.
• Install both pump systems: Confirm both return pumps, return nozzles, power centers, and rear-sump components are correctly installed before startup.
• Plan top-off separately: The XXL does not include the smaller models’ ATO reservoir, so top-off equipment or routine manual top-off should be planned before stocking.
• Use RO/DI water: Use RO/DI water for salt mixing and top-off to support clean reef chemistry.
• Cycle before livestock: Establish biological filtration before adding fish or corals.
• Use ReefBeat acclimation: Acclimate corals gradually under the dual ReefLED fixtures.
• Maintain the rear sump: Clean the filter sock, service the skimmer, inspect both pumps, and keep the rear sump clear for reliable flow.
