Red Sea Max Nano G2 XXL and White Cabinet

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

This XXL system gives reef keepers a much larger reef canvas than the smaller MAX NANO models while preserving the clean all-in-one layout that keeps equipment behind the display. 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 white marine-spec cabinet for a polished furniture-style installation.

Red Sea MAX NANO G2 XXL White Reef System

• Largest MAX NANO G2 with white cabinet: The XXL gives reef keepers the biggest MAX NANO footprint with a clean white stand for a bright, contemporary display.
• 200 litre / 53 gallon total volume: The larger system volume supports better stability, more coral placement, and more display presence than smaller nano systems.
• Complete aquarium and stand package: This version includes the XXL aquarium and matching white cabinet, reducing stand-selection uncertainty and giving the installation a coordinated look.
• Dual ReefLED G2 lighting: Two ReefLED G2 60 fixtures provide reef-specific lighting coverage across the longer 90 cm display.
• Dual return pumps: Two 1550 LPH Sicce pumps move water through the rear sump and return it through two adjustable nozzles.
• Large all-in-one simplicity: The system offers a larger reef display while keeping core filtration hidden behind the aquarium rather than in a separate below-tank sump.

XXL Ultra-Clear Glass and White Cabinet Styling

• 12 mm rimless ultra-clear glass: Red Sea lists the XXL with 12 mm ultra-clear glass for a strong premium display with excellent viewing clarity.
• 90 cm long reef canvas: The 90 x 55 x 50 cm aquarium gives room for larger aquascapes, multiple coral islands, open swimming areas, and more natural reef proportions.
• Bright white cabinet finish: The white stand gives the large system a clean, modern, lighter visual profile that suits contemporary interiors and display spaces.
• Open-top design: The rimless layout makes aquascaping, cleaning, feeding, and coral placement easier while maintaining a high-end look.
• Hidden equipment presentation: The rear sump and screen keep filtration hardware out of sight so the reef remains the visual focus.
• Room centerpiece potential: The XXL White system is large enough to become a major display feature while remaining cleaner and simpler than many custom sump-based reef builds.

Dual ReefLED G2 60 Lighting and ReefBeat Control

• Two included ReefLED G2 60 lights: The XXL uses dual app-controlled ReefLED fixtures to cover the longer display more effectively.
• Coral-focused REEF-SPEC output: Each light can be tuned from 10,000K reef-white to 23,000K REEF-SPEC Blue.
• Enhanced fluorescence support: Violet, ultraviolet, and boosted 470 nm blue wavelengths help corals and fish display strong colour.
• Dedicated moonlight channels: The separate 3W moonlight channels provide subtle nighttime viewing.
• ReefBeat smart functions: ReefBeat provides scheduling, acclimation, lunar cycle moonlight, random clouds, staggered sunrise and sunset, and custom manual modes.
• Rotatable light arms: The mounting arms rotate upward for access during cleaning, coral placement, and rear-sump maintenance.
• More even display coverage: Dual fixtures help support broader coral placement and a more balanced look across the 90 cm aquarium.

Hidden Rear Sump and REEF-SPEC Filtration

• Fully concealed rear sump: Filtration equipment sits behind the display and is covered by a rotatable screen for a clean room-facing presentation.
• Surface-skimming intake: Water enters through a removable surface skimmer to help remove surface film and maintain water clarity.
• 225 micron filter sock: Mechanical filtration captures fine suspended particles before water continues to the skimmer and media area.
• MAX NANO protein skimmer: The integrated protein skimmer removes dissolved organics and helps oxygenate the water.
• REEF-SPEC skimmer performance: 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: The built-in media area supports carbon or other chemical media for water polishing or targeted filtration.
• Bubble trap and dual nozzles: Water passes through a bubble trap before returning to the display through two multidirectional adjustable return nozzles.

Dual Sicce Pumps and Upgrade-Ready Control

• 2 x 1550 LPH Sicce return pumps: The XXL includes two return pumps for strong flow through the rear sump system.
• Approximately 10x turnover: Red Sea lists the MAX NANO G2 circulation system as moving the aquarium’s water volume about ten times per hour.
• Two adjustable return outlets: Dual returns improve flow direction options across the longer display.
• Two pump power centers: Convenient pump switches make feeding, cleaning, and service easier on the larger XXL system.
• NanoMat ready: The rear sump is compatible with optional Red Sea NanoMat automatic fleece-roll filtration.
• ReefATO+ ready: The system is ready for optional ReefATO+ upgrade functionality for advanced top-off, temperature monitoring, and leak detection.
• No included ATO reservoir: The automatic top-off reservoir supplied with smaller MAX NANO G2 models is not included with the XXL, so top-off planning is important.

Application Notes for the XXL White System

• Coral planning: Dual ReefLED G2 60 lighting and the 90 cm length provide more flexibility for mixed reef layouts and broader coral placement.
• Flow planning: The dual return pumps provide strong turnover, but additional wavemakers may be useful for SPS-heavy or dense coral systems.
• Evaporation planning: Since the XXL does not include the smaller models’ ATO reservoir, plan top-off equipment or routine freshwater replacement before setup.
• Not included: ATO reservoir, livestock, rock, sand, salt, heater, wavemaker, test kits, dosing equipment, optional NanoMat, optional ReefATO+, and additional filtration media are sold separately unless stated otherwise.

Setup and Installation Notes

• Assemble the cabinet first: Build and level the white cabinet according to Red Sea’s instructions before placing the aquarium on top.
• Confirm level support: Check the cabinet and aquarium before filling.
• Install rear sump equipment: Confirm both return pumps, the skimmer, filter sock, media chamber, bubble trap, surface skimmer, power centers, and return nozzles are installed correctly.
• Plan top-off separately: The XXL does not include the smaller models’ ATO reservoir, so evaporation replacement should be planned before livestock is added.
• Use RO/DI water: Use RO/DI water for saltwater mixing and top-off to maintain stable reef chemistry.
• Cycle before stocking: Establish biological filtration before adding fish or corals, then stock gradually.
• Use lighting acclimation: Use ReefBeat acclimation settings to introduce corals gradually under the dual ReefLED fixtures.
• Service the rear sump: Clean the filter sock, service the skimmer, inspect both return pumps, and keep the rear sump clear for consistent flow.
