## Overview

The Ultum Nature Systems Ultra Clear Rimless Aquarium is a premium 3-gallon tank crafted from 91% clarity low iron glass with precision 45° mitered edges bonded by durable German silicone. Designed using the golden ratio for optimal aesthetics and depth, it includes a black anti-slip leveling mat for stability. Perfect for aquascaping enthusiasts seeking a minimalist, high-clarity display that blends seamlessly into modern interiors.

## 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: 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 😍

## Questions & Answers

**Q: I want to use this to raise Monarchs inside. Has anyone found a mesh lid that fits this aquarium - not a fine mesh lid, something mid-aerated.**
A: I looked for lids for this size and they don't seem to exist.  You could easily make one though.

**Q: 45L.... 2 gallons?
Hello! I'm quite confused in here, according to the manufacturer website the 45L model is 3.8 gal... who's right?**
A: 3.8 gallons. 45L is model number.

**Q: The product information says the tank is 45 L and 3.4 gallons, but these are not equivalent volumes. What is the actual volume of the tank?**
A: It’s 3.4 gallons.  45 L is the model number.

**Q: Is the tank shipped in a cardboard box or wooden crate?**
A: It was well packed in cardboard box not wooden crate.
