Aquarium systems ship by scheduled freight, not by parcel carrier. Checkout shows a single flat Scheduled Freight Delivery charge for continental U.S. addresses, and you see the exact amount in the cart before you pay. The $10 livestock Box & Handling Fee and the $349 livestock free-shipping threshold do not apply to an aquarium system. Ask us to confirm availability and the delivery arrangements for your address before you order.

Freight delivery is offered to the continental U.S. at checkout. We do not ship to Alaska or Hawaii. Installation and maintenance is a local service in Key West and the Florida Keys; everywhere else we ship the system and you arrange the install.

Description

The Red Sea MAX NANO G2 XXL Aquarium (53 Gal) is a fully equipped, plug-and-play reef system built around Red Sea’s REEF-SPEC standards for lighting, filtration, and circulation. Everything needed to run a healthy reef ships in the box, so there’s no guesswork over compatible equipment.

MAX NANO G2 XXL specifications

Display volume 45 US gallons
Total system volume 53 US gallons
Tank footprint (L x W) 35.4 x 21.7 inches
Tank height 19.7 inches
Total height on the cabinet 54 inches, measured to the top of the tank and not counting the light
Cabinet finishes Black or white
Warranty Up to 5 years for eligible original U.S. purchasers who register the new system with Red Sea within 90 days. Non-transferable.

Volumes are Red Sea’s figures for the system as built. Actual water volume in your room will be lower once rock and sand go in, and the display figure is the tank itself rather than the whole system. The cabinet is optional on the MAX NANO, so measure your stand as well as your ceiling before you order.

  • Total System Volume: 53 Gallons
  • Dimensions: 35.4″ L x 21.7″ W x 19.7″ H
  • Glass: Rimless, ultra-clear 12mm glass
  • Lighting: 2x ReefLED G2 60 included, Wi-Fi controlled via the ReefBeat app
  • Filtration: Rear all-in-one sump with removable surface skimmer, filter sock, MAX protein skimmer, and media chamber
  • Cabinet: Optional marine-spec cabinet in black or white, sold with or without the tank
  • Warranty: Eligible original U.S. purchasers can receive five-year warranty coverage by registering an eligible new Red Sea system within 90 days. The warranty is non-transferable.

The rear sump is ReefATO+ and NanoMat-ready, so the system can be upgraded later with Red Sea’s auto top-off and fleece-roller filtration (both sold separately) without any modification. The included ReefLED G2 lighting runs the full REEF-SPEC spectrum, from a 10,000K reef-white to a 23,000K REEF-SPEC blue, with sunrise/sunset, lunar cycle, and acclimation programs built into the ReefBeat app.

We are an authorized Red Sea dealer and can order any MAX NANO G2 configuration directly. See the full official spec sheet and augmented-reality size preview on Red Sea’s website.

Shipping & Returns

  • Equipment and dry goods ship at their own rate. Free shipping at $349 or more applies to qualifying livestock only — corals, fish, inverts and live copepods. The $10 box & handling fee is a livestock packing fee and does not apply to dry-goods orders.
  • All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
  • Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
  • Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
