Red Sea Max Nano G2 XL and Black Cabinet

The Red Sea Max Nano G2 XL and Black Cabinet is a premium 125 litre / 33 gallon all-in-one reef aquarium and stand package designed for reef keepers who want a larger MAX NANO G2 display with integrated equipment, clean black furniture-style support, and Red Sea’s reef-ready rear-sump layout.

This complete XL package pairs the MAX NANO G2 XL aquarium with a matching black marine-spec cabinet, giving the system a polished high-contrast look while providing the core reef equipment needed to build a compact but serious coral display. The system includes rimless 10 mm ultra-clear glass, ReefLED G2 60 lighting, a hidden rear sump, REEF-SPEC protein skimming, 1550 LPH Sicce return circulation, automatic top-off, pump power control, NanoMat readiness, and optional ReefATO+ compatibility.

Red Sea MAX NANO G2 XL Black Reef System

• Complete aquarium and cabinet package: This version includes both the MAX NANO G2 XL aquarium and the matching black Red Sea cabinet for a finished display installation.
• 33 gallon XL system volume: The 125 litre total volume gives more water stability, coral room, and aquascaping depth than smaller nano reef systems while remaining easier to manage than a large custom reef tank.
• Black cabinet presentation: The black stand gives the system a clean, modern, high-contrast look that helps equipment and shadows visually recede while coral colour stands out.
• Plug-and-play reef engineering: Lighting, skimming, filtration, return flow, surface skimming, top-off, cabinet support, and pump control are designed as a coordinated Red Sea system.
• Excellent upgrade from smaller nanos: The XL is ideal for aquarists who like the simplicity of an all-in-one aquarium but want more aquascaping space and stronger long-term reef potential.

Ultra-Clear XL Display and Black Cabinet Finish

• Rimless 10 mm ultra-clear glass: Red Sea lists the XL with 10 mm ultra-clear glass for a clean, sharp display that shows coral colour, fish movement, and reef lighting with excellent clarity.
• Wider and deeper MAX NANO footprint: The 50 x 60 x 50 cm display gives reef keepers more room to build a dimensional aquascape with negative space, rock islands, caves, shelves, and coral growth zones.
• Open-top design: The rimless top gives the aquarium a modern look and keeps access simple for feeding, coral placement, cleaning, and aquascaping.
• Matching black marine-spec cabinet: The cabinet is built for the system and provides a coordinated furniture-style base rather than a generic support stand.
• Clean equipment concealment: The rear sump and rotatable rear screen keep equipment hidden while still allowing practical access for maintenance.
• Strong display impact: The black cabinet visually frames the reef, making the aquarium a strong focal point in living rooms, offices, showrooms, and dedicated aquarium spaces.

ReefLED G2 60 Lighting and Smart Reef Control

• Included ReefLED G2 60: The XL includes one ReefBeat app-controlled ReefLED G2 60 light matched to the system for reef aquarium use.
• Coral-focused spectrum: ReefLED G2 60 delivers Red Sea’s REEF-SPEC lighting with output adjustable from 10,000K reef-white to 23,000K REEF-SPEC Blue.
• Colour and fluorescence support: Violet, ultraviolet, and boosted 470 nm blue wavelengths help enhance coral fluorescence and fish colour.
• Dedicated moonlight: The 3W moonlight channel allows low-level nighttime viewing without using the main daytime light channels.
• ReefBeat scheduling: App control includes daily schedules, acclimation, random clouds, lunar cycle moonlight, staggered sunrise and sunset, and custom manual modes.
• Rotatable arm: The light mount rotates upward to make rear-sump service, cleaning, and reefscaping more convenient.

Hidden REEF-SPEC Rear Sump

• Integrated filtration chamber: The complete rear sump keeps equipment out of the main display and hidden behind a rotatable screen.
• Surface skimmer intake: Water is pulled from the surface to help remove surface film and maintain better gas exchange, clarity, and light penetration.
• 225 micron filter sock: Mechanical filtration helps trap floating debris before it reaches the skimmer and media sections.
• MAX NANO XL protein skimmer: The skimmer helps remove dissolved organic waste and oxygenate the water, supporting nutrient control in a coral-focused reef system.
• REEF-SPEC skimmer performance: The skimmer is designed to process the aquarium volume approximately three times per hour with a 3 to 1 water-to-air ratio.
• Chemical media chamber: The rear sump includes a dedicated media area for carbon or other chemical filtration media when the aquarium needs water polishing or targeted filtration.
• Bubble trap design: The sump path helps reduce microbubbles before water returns to the display.

Circulation, Top-Off, and G2 Upgrade Features

• 1550 LPH Sicce return pump: The XL uses a 1550 LPH / 409 GPH Sicce pump to move water through the rear filtration system and return it to the display.
• Approximately 10x system turnover: Red Sea lists the MAX NANO G2 circulation system as moving the tank’s full water volume about ten times per hour.
• Adjustable return direction: The multidirectional nozzle can be aimed to improve flow around rockwork and help reduce dead spots.
• Integrated ATO reservoir: The included automatic top-off uses a hidden 2.7 L / 0.7 gal freshwater reservoir designed to support approximately 2-3 days of evaporation.
• NanoMat ready: The removable filter sock compartment can be upgraded with an optional Red Sea NanoMat for automated fleece-roll mechanical filtration.
• ReefATO+ ready: The rear sump is prepared for optional ReefATO+ functionality for advanced top-off, temperature monitoring, and leak detection.
• Pump power center: Built-in pump switches make it easier to turn off the skimmer and return pump for feeding and maintenance.

Application Notes for the XL Black System

• Best use: Ideal for reef keepers who want a premium compact reef system with more aquascaping room than the smaller MAX NANO models.
• Coral suitability: The ReefLED G2 60, rear sump, protein skimmer, and 33 gallon volume support soft coral, LPS, and carefully planned mixed reef aquariums.
• Flow planning: The return pump provides strong turnover, but additional internal flow may be useful for coral-heavy rockwork or higher-flow coral placement.
• Cabinet advantage: The included black cabinet creates a coordinated installation and avoids the uncertainty of matching the aquarium to a generic stand.
• Not included: 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 black cabinet according to Red Sea’s instructions before placing the aquarium on top.
• Confirm level support: Check that the cabinet and aquarium are level before filling.
• Install equipment before startup: Confirm the rear sump, skimmer, filter sock, media chamber, pump, ATO reservoir, and return nozzle are properly installed before adding livestock.
• Use RO/DI water: Use RO/DI water for saltwater mixing and evaporation top-off to maintain cleaner reef chemistry.
• Cycle before stocking: Establish biological filtration before adding fish or corals, then stock the reef gradually.
• Use ReefBeat acclimation: Start corals with appropriate light acclimation and increase output gradually.
• Service regularly: Clean the filter sock, maintain the skimmer, refill the ATO reservoir, and keep the rear sump clear to preserve flow and filtration performance.
