Red Sea Max Nano G2 Complete System - Black

The Red Sea Max Nano G2 Complete System - Black is a premium 75 litre / 19.8 gallon all-in-one nano reef aquarium and stand package designed for hobbyists who want a compact Red Sea reef system with serious equipment, clean cabinet integration, and a polished black display finish.

Built for reef keepers who want a smaller aquarium without settling for a basic starter tank, the MAX NANO G2 Complete System combines a rimless ultra-clear glass display, ReefLED G2 60 lighting, REEF-SPEC filtration, protein skimming, rear-sump equipment concealment, 950 LPH circulation, integrated auto top-off, convenient pump power control, and a matching black marine-spec cabinet. It is an excellent choice for a first reef aquarium, a compact coral-focused display, an office reef, a bedroom reef, or an advanced hobbyist’s clean secondary system.

Red Sea MAX NANO G2 Cube Reef System

• Complete nano reef package: The MAX NANO G2 Complete System is supplied as a coordinated tank and stand system with the core lighting, filtration, circulation, skimming, rear sump, auto top-off, and cabinet components already selected to work together.
• Compact 20 gallon class footprint: The 75 litre / 19.8 gallon total system volume gives new and experienced reef keepers a manageable aquarium size while still providing the stability and equipment capacity needed for a serious nano reef.
• Cube-style reef layout: The 45 cm x 45 cm x 45 cm display gives balanced front-to-back depth, height, and length, making it easier to create island aquascapes, central bommies, cave structures, or negative-space reef layouts in a compact footprint.
• All-in-one simplicity: The hidden rear sump keeps filtration hardware out of the main display, reducing visible clutter and simplifying the build compared with choosing separate equipment from multiple brands.
• Black cabinet presentation: The black cabinet gives the system a modern, high-contrast look that helps cables, equipment shadows, and cabinet space visually recede while making coral colour and reef lighting stand out.
• Great first reef or premium upgrade: The MAX NANO G2 is friendly enough for a first reef aquarium but still equipped with reef-focused hardware that experienced aquarists will appreciate.

Ultra-Clear Cube Display and Modern Black Stand

• Rimless ultra-clear glass: The aquarium uses 8 mm ultra-clear front and side panels with a clean rimless design for a brighter, sharper view of fish, coral, rockwork, and shimmer.
• Compact placement flexibility: The cube format allows the MAX NANO G2 to fit into spaces where a larger reef aquarium would not be practical, including condos, offices, bedrooms, reception areas, and smaller living rooms.
• Strong aquascaping balance: Equal length, width, and height give the aquarium more aquascaping depth than many narrow nano tanks, making it easier to build a reef that looks dimensional instead of flat.
• Open-top access: The rimless open-top layout makes feeding, coral placement, cleaning, rockwork adjustments, and rear-sump access easier during routine maintenance.
• Hidden equipment look: The rear filtration compartment and rotatable sump screen keep the display focused on the reef instead of visible filters, heaters, cords, and mechanical hardware.
• Furniture-style finish: The included black stand creates a finished installation and gives the aquarium the appearance of a complete display piece rather than a tank placed on a generic cabinet.

ReefLED G2 60 Lighting with ReefBeat Control

• Included ReefLED G2 60: The MAX NANO G2 Complete System includes Red Sea’s ReefBeat app-controlled ReefLED G2 60 light, giving the aquarium a reef-specific lighting platform matched to the tank size.
• REEF-SPEC coral lighting: ReefLED G2 60 is designed to deliver coral-focused output with tunable light from 10,000K reef-white to 23,000K REEF-SPEC Blue.
• Enhanced fluorescence: The REEF-SPEC Blue channel is supported by violet, ultraviolet, and boosted 470 nm blue output to help corals and fish show strong colour and fluorescence.
• Dedicated moonlight channel: A separate 3W moonlight channel provides low-level nighttime illumination without relying on the main daytime light channels.
• ReefBeat Wi-Fi control: The ReefBeat app allows lighting schedules, channel adjustments, acclimation programming, staggered sunrise and sunset, random clouds, lunar cycle moonlight, and custom viewing modes from a compatible smart device.
• Rotatable light mount: The custom mounting system attaches to the rear wall of the aquarium and can rotate upward for aquascaping, rear-sump maintenance, and cleaning access.
• Excellent nano reef presentation: The ReefLED G2 60 helps create strong coral colour, attractive shimmer, and a bright polished display effect that makes the compact cube feel like a true reef showcase.

REEF-SPEC Rear Sump Filtration

• Integrated rear sump: The rear filtration chamber hides the core filtration equipment behind the display while keeping it accessible from above for regular service.
• Surface-skimming intake: Water enters the filtration path through a removable surface skimmer, helping remove surface film and improve water clarity, gas exchange, and light penetration.
• 225 micron filter bag: The supplied micron filter bag captures suspended particles before water continues through the skimmer and media areas, helping keep the display cleaner.
• MAX NANO protein skimmer: The integrated skimmer is the core of the filtration system, helping remove dissolved organic waste and oxygenate the water in a compact reef environment.
• REEF-SPEC skimmer design: The skimmer is designed to process the aquarium water volume multiple times per hour with a 3 to 1 water-to-air ratio, supporting nutrient control in a small coral-focused system.
• Quiet skimmer operation: The skimmer includes an adjustable outlet gate, air-intake silencing, and outlet sound reduction to help maintain stable skimming without unnecessary noise.
• Fixed media shelf: The rear sump includes a positive-flow media shelf and supplied REEF-SPEC Carbon for water polishing during the early life of the aquarium.
• Bubble trap and return path: The sump layout helps reduce microbubbles before the water returns to the display, giving the aquarium a cleaner viewing area.

Circulation and Water Movement

• 950 LPH return pump: The included return pump circulates approximately 950 litres / 240 gallons per hour through the filtration system.
• High turnover for a nano reef: The pump moves the full system volume many times per hour, helping maintain filtration performance and steady water movement through the rear sump.
• Adjustable return nozzle: Water returns to the aquarium through a discreet multidirectional nozzle that can be aimed to help reduce dead spots behind rockwork and around corals.
• Supports coral nutrient delivery: Proper water movement helps deliver oxygen, minerals, and suspended nutrients to corals while helping prevent detritus from settling in low-flow areas.
• Clean equipment footprint: The pump is hidden in the rear filtration area, keeping the main display free of bulky return hardware.
• Additional flow planning: Depending on aquascape and coral selection, many reef keepers may still add a small wavemaker to create broader random flow for LPS, soft corals, or higher-flow coral placements.

Auto Top-Off and G2 Upgrade Readiness

• Integrated automatic top-off: The MAX NANO G2 includes an ATO system to help stabilize rear-sump water level as evaporation occurs.
• Hidden freshwater reservoir: The 1.5 litre / 0.4 gallon freshwater reservoir is concealed behind the rear sump screen to keep the system clean and uncluttered.
• About three days of top-off support: The reservoir helps reduce daily top-off demands and supports more consistent skimmer and return-pump operation between refills.
• NanoMat ready rear sump: The rear sump is designed to accept the optional Red Sea NanoMat upgrade, allowing future automatic fleece-roll mechanical filtration without starting over with a different aquarium.
• ReefATO+ ready layout: The system is ready for the optional Red Sea ReefATO+ upgrade for aquarists who want advanced auto top-off, temperature monitoring, and leak detection functionality.
• Run stock or build forward: The aquarium can be run cleanly with the included equipment, then upgraded as the reef matures or as the aquarist wants more automation and convenience.

Black Cabinet and Pump Power Center

• Included black cabinet stand: This complete system includes the matching black Red Sea cabinet, creating a coordinated tank-and-stand package.
• Marine-spec cabinet construction: The stand is designed for marine aquarium use with a laminate exterior, weather-resistant painted doors, push-open hardware, and soft-close stainless steel hinges.
• Convenient pump power center: Built-in on/off switches for the skimmer and circulation pump make feeding and maintenance easier without unplugging equipment from behind the aquarium.
• Cleaner cord management: Centralized pump control helps reduce the loose-cord clutter that often makes small custom reef systems look unfinished.
• Maintenance-friendly access: The rotatable rear screen, accessible skimmer, removable filter bag, media shelf, top-off reservoir, and pump switches are arranged for practical day-to-day service.
• Modern black display look: The black cabinet pairs well with dark furniture, entertainment rooms, offices, and high-contrast reef displays where coral colour is intended to be the focal point.

Application Notes for Nano Reef Keepers

• Best use: The MAX NANO G2 Complete System is designed for saltwater nano reef aquariums where appearance, equipment integration, coral-focused lighting, and compact maintenance matter.
• Coral suitability: The ReefLED G2 60, REEF-SPEC filtration, rear sump, and skimmer make the system suitable for carefully planned soft coral, LPS, and mixed nano reef displays.
• SPS planning: SPS-focused nano reefs require stable alkalinity, calcium, magnesium, nutrients, temperature, salinity, and flow, so coral selection and placement should be planned carefully.
• Stocking discipline: Nano systems are rewarding but sensitive, so fish and invertebrates should be chosen around adult size, compatibility, swimming behaviour, and nutrient load.
• Top-off consistency: The integrated ATO helps with evaporation stability, but the reservoir still needs to be checked and refilled regularly with suitable freshwater.
• Optional upgrades: NanoMat, ReefATO+, heater, wavemaker, test kits, dosing equipment, rock, sand, salt, livestock, and extra filtration media are sold separately unless specifically stated.

Setup and Installation Notes

• Choose the location first: Place the aquarium where the floor is level, the cabinet can be accessed, and water changes can be performed safely without moving the system.
• Assemble the cabinet correctly: Build and level the stand according to Red Sea’s instructions before placing the aquarium on top.
• Confirm level support: Check that the stand and aquarium are level before filling, since rimless glass aquariums need even support.
• Install the rear sump components: Confirm the surface skimmer, filter bag, protein skimmer, media shelf, carbon, bubble trap, return pump, ATO reservoir, and return nozzle are correctly positioned before startup.
• Use proper source water: Use RO/DI water for saltwater mixing and top-off to help reduce nuisance algae, mineral buildup, and avoidable contaminants.
• Cycle before stocking: Establish biological filtration before adding fish or corals, then stock slowly to maintain water quality and stability.
• Use ReefBeat acclimation: Start new corals under appropriate acclimation settings and increase light intensity gradually to reduce sudden light stress.
• Maintain the filtration path: Clean or replace mechanical filtration, service the skimmer, refill the ATO reservoir, and keep the rear sump clear so water flow remains strong.
