Red Sea MAX NANO G2 XXL Aquarium System

The Red Sea MAX NANO G2 XXL is the largest aquarium in the MAX NANO family, combining the convenience of an all-in-one reef system with substantially more display space than a traditional nano aquarium.

With a 53-gallon total system volume and a 45-gallon display, the MAX NANO G2 XXL provides enough room for a more ambitious reefscape while keeping all major filtration equipment hidden in the integrated rear sump. Its 35.4" x 21.7" footprint offers excellent horizontal swimming room and aquascaping flexibility without requiring a traditional sump beneath the aquarium.
