UNS 180U Ultra Clear Rimless Aquarium (156 GAL) - Ultum Nature Systems

Ultra Clear Tanks by Ultum Nature Systems
Ultra Clear Rimless Aquarium mitered edge- Ultum Nature Systems | Aqua Lab Aquaria
These rimless aquariums are carefully crafted using 91% clarity Diamant glass, a highly transparent extra clear glass with very little residual green color.  The low iron content in the glass provides uninterrupted crystal clear visibility.  The 45° mitered edges are bonded together using high performance German silicone specifically designed for aquarium construction.  Rather than following the conventional sizing of other rimless aquarium brands, Ultum Nature Systems keeps the aquascaper in mind by focusing on the golden ratio.  The additional space makes it easier to achieve that sense of perspective and truly show depth in an aquascape.
