Let us Begin with the Aquarium

Built from the footprint of the Award-Winning Fusion Aquarium series, the NUVO EXT is an Innovative Marine first. The first to incorporate an all-glass overflow. The first with a "Bean Animal" Safety drain system. And the first that allows 100% room for unobstructive aquascaping.

The NUVO EXT (External Overflow) design unites beauty with purpose, taking a page from the proven and tested Bean Animal style safety drain system. The drain works in tandem, reducing noise and preventing accidental spillage and blockage. Creating silence, safety, and redundancy.

Out of the box, the NUVO EXT is today's modern reef ready system that is made to be customized just the way you like it as well as the freedom for aquascaping creativity.
