UNS 90SS - 33.3 Gallon Ultra Clear Rimless Aquarium
Product Overview
The UNS 90SS 33.3 Gallon Ultra Clear Rimless Aquarium provides an expansive, mid-sized shallow canvas for aquascaping. Sharing the wide footprint of the popular 90S model but featuring a significantly lower 9.84" height, the 90SS offers an ultra-modern "super shallow" silhouette that prioritizes horizontal space and generous front-to-back depth (22.04"). 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 35.43" length paired with a low 9.84" height delivers exceptional PAR light efficiency to grow demanding carpeting plants easily while providing a dramatic "pond-style" top-down perspective.
- Expansive Front-to-Back Depth: Features a generous 22.04" width, giving aquascapers essential room to build complex hardscape depth of field, 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 (90SS) aquarium over a standard 90cm tank?
Super shallow aquariums prioritize horizontal footprint over vertical 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. Why is a leveling mat mandatory for rimless aquariums?
A filled 33.3-gallon aquarium weighs over 300 lbs when accounting for water, rockwork, and substrate. Because rimless glass tanks rest directly on their base panel without a raised plastic 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.
