## Overview

The UNS Ultra Clear Rimless Tank is a 7.1-gallon, 30x30x30 cm aquarium crafted from 91% clarity low iron Diamant glass with 5mm thickness and precision 45° mitered edges. Designed using the golden ratio for optimal visual depth, it features German-made silicone bonding for durability and includes a black leveling mat for stability. This minimalist, rimless tank is perfect for aquascaping enthusiasts seeking a premium, modern display.

## Description

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 wife's yoga mat.

Review: looks great - i think a large part about aquarium review is longevity, which i cant review yet. but for the tank itself, it is very nice. the glass is clear. the whole thing looks very clean. its a nice tank and worth the premium imo.
Review: Beautiful tank! - I got the 3 gallon nano tank for my shrimp. This is a beautiful tank and the quality is excellent. It showed up well packaged and on time. I’ve wanted this tank for a long time and it did not disappoint. UNS is worth the extra money. I got the UNS glass lid with clips and it’s perfect 😍
