## Overview

The Ultum Nature Systems 5N Clear Rimless Tank is a 4.6-gallon aquarium crafted from 91% clarity diamante glass with low iron content for unmatched transparency. Featuring 45° mitered edges bonded with high-quality German silicone, it offers a seamless rimless design. Its dimensions follow the golden ratio to enhance aquascaping depth and perspective. The tank includes a black nano foam leveling mat for stability and surface protection, making it a premium choice for indoor aquatic displays.

## 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° 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: Crystal clear, sturdy - Huge fan of UNS tanks. This is my second one. My betta is happy and healthy.
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 😍

## 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.

Very impressed with the quality of this tank. Took two days longer to arrive which resulted in plants I’d purchased to almost perish…still waiting to see if they make it. Would definitely order again!!
