NUVO Aquariums have a long history of transforming the way you reef and our next generation of Full Size Aquariums will change it again! From the start, Innovative Marine`s vision was to create an aquarium that the overflow flawlessly integrates into the experience and is in tune with your dream set up. Introducing the NUVO Full Size EXT and her sister tank the INT.

By offering two styles you get a choice: The EXT`s external overflow system boasts a robust center glass overflow, dual LOC-LINE returns, and a custom "Bean Animal" style safety drain system.

The INT`s internal overflow system possess an industry first Trapezoid Infinity Overflow, dual return LOC-LINE nozzles and a custom "Bean Animal" style safety drain system.
When crafting a premium aquarium no detail is ever over looked or underachieved. Utilizing only the highest caliber components, both the EXT and INT embrace Innovative Marine`s award-winning craftsmanship, diamond edged ultra-thick high clarity low iron glass, laser cut acrylic weir and distinct black silicone lines forged from a bloodline of distinction.

Completely Silent, efficient and fully customizable the Full Size NUVO Aquariums were born for the next generation of products for the hobbyist.

Yes, I would recommend this.

High quality Aquarium!!

Pros: Quality.

Cons: None really. It’s just heavy.

What an amazing aquarium. The quality is top notch and it’s extremely heavy. I would say it weighs a little over 200lbs. I’m definitely buying another nuvo ext in the future.
