Ultum Nature Systems 20C

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, our dimensions keep 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.  Each Ultra Clear Tank comes with a black leveling mat which is crucial so you don’t have to cut up your yoga mat.
