## Overview

The Ultum Nature Systems Ultra Clear Rimless Nano Aquarium features 91% clarity low iron glass with 45° mitered edges bonded by high-quality German silicone, designed using the golden ratio for optimal aesthetics and depth. This 5-gallon tank includes a black leveling mat for stability, offering a premium, minimalist aquarium experience favored by aquascaping enthusiasts.

## Description

These rimless aquariums are carefully crafted using 91% clarity diamante 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 degree 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 aqua caper 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 aqua cape. 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: Amazing tank - Amazing tank! Perfect size, so clear it seems like the fish are floating and such a great design. I love this tank!

## Questions & Answers

**Q: How long is the tank?**
A: I have the 7 gallon tank.  It is a perfect square: 12 x 12 x 12 inches.

**Q: how thick is the glass?**
A: It is thin. About 1/16 inch.

**Q: Is there a glass cover available that will fit this and stay in place for fish that like to jump?**
A: The Ultum systems are meant for beautiful aquascapes, unencumbered by lids. For the 4.6 gallon, the best solution might be to have a piece of glass custom cut. An auto glass shop will do this, and smooth the edges, for about $12 - $15 USD.

**Q: does it come with a lid?**
A: No, it does not come with a lid. However, if you go to an auto glass shop, a custom cut piece of regular glass, with smoothed edges, will cost you very little - about $12. Alternatively, you could get a piece of pre-cut acrylic. Amazon sells such a thing.
