What's a NUVO EXT Reef Ready?

"EXT" stands for External and "Reef Ready" means it needs a sump. The name was coined to describe the style of overflow and drain system used on this series of NUVO aquariums. 


The EXT's are built with an external glass overflow, giving hobbyist 100% usable display space. Water cascades through the center weirs, enters a "Bean Animal" drain* and flows into a sump down below.

What's a "Bean Animal" Drain?

A "Bean Animal" is a 3 drain pipe overflow system consisting of: one primary siphon, one primary emergency and a secondary emergency.
