UNS 120SS Ultra Clear Rimless Aquarium (47.6 GAL) - Ultum Nature Systems

Product Overview

The Ultum Nature Systems (UNS) 120SS 47.6 Gallon Ultra Clear Rimless Aquarium provides an expansive canvas for aquascaping. Sharing the wide horizontal footprint of the 120S model but featuring a significantly lower 9.84" vertical height, the 120SS offers an ultra-modern "super shallow" silhouette. This format is ideal for Iwagumi layouts, shallow reef designs, or pond-style scapes with emergent growth.

Key Features & Benefits

• 91% Diamant Ultra-Clear Glass: Premium low-iron glass eliminates the green tint found in standard aquariums for true-to-life color accuracy.
• 45° Mitered Edges & German Silicone: Precision-cut 45-degree mitered joints double the bonding surface area for high-performance German clear silicone, forming stronger seams.
• Super Shallow Panoramic Proportions: The 47.24" length paired with a low 9.84" height offers intense PAR light penetration to effortlessly grow demanding carpeting plants while providing a dramatic "pond-style" top-down perspective.
• Expansive Golden Ratio Depth: Features a generous 23.62" width, giving aquascapers essential breathing room to build complex hardscape perspective, substrate slopes, and multi-layered plant arrangements.
• Signature Laser-Etched Branding: Features a clean, laser-etched UNS logo in the glass corner for an authentic, museum-quality finish that will not peel or fade.
• Acoustic Leveling Mat Included: Includes a pre-cut dense foam leveling mat to absorb micro-vibrations, level minor surface imperfections, and prevent structural stress cracks under heavy load.

Frequently Asked Questions

1. Why select a super shallow (120SS) aquarium over a standard 120cm tank?

Super shallow aquariums prioritize horizontal footprint over height. The 9.84" low height provides exceptional PAR light penetration to effortlessly grow difficult carpeting plants (like Hemianthus callitrichoides or Glossostigma) while enabling wood and hardscape structures to breach the water surface for a dramatic, open-top display.

2. What livestock is best suited for a 47.6-gallon super shallow tank?

The UNS 120SS offers exceptional swimming surface area for schooling nano fish (such as Tetras, Rasboras, or Danios), active dwarf shrimp colonies, Corydoras, and bottom-dwelling species.

3. Why is a leveling mat mandatory for rimless aquariums?

A filled 47.6-gallon aquarium weighs over 450 lbs when accounting for water, rockwork, and substrate. Because rimless glass tanks rest directly on their base panel without a raised plastic perimeter frame, even a microscopic grain of sand on a stand can create concentrated stress points under that weight. The included dense foam mat absorbs micro-imperfections and distributes weight evenly across the entire footprint to prevent glass stress cracks.
