Description
Product Overview
The limited edition UNS 90L Rimless Aquarium pairs sleek proportions with premium details designed to elevate long-format aquascapes. Crafted with 91% clarity Diamant glass and signature 45° mitered edges, this version features a frosted blue background with a soft satin finish that enhances depth and visual contrast. A heat-fused white bottom adds a clean, elevated touch while offering a durable, peel-resistant finish built for long-term display.
At 21.3 gallons, the UNS 90L’s extended footprint makes it ideal for panoramic layouts, flowing hardscape compositions, and planted scenes with strong horizontal movement. Its shallow, long design offers extra room for creative depth, schooling fish, and layered details without overwhelming smaller spaces. The frosted backdrop and white base give the tank a polished, gallery-style presentation that helps every element stand out.
Key Features & Benefits
Frosted Blue Background: A soft, satin-finished frosted blue backdrop adds subtle depth, accentuates green aquatic plants, and creates vibrant visual contrast.
Heat-Fused White Bottom: Features a durable, heat-fused white base panel that creates an elevated foundation for your substrate with a long-lasting, peel-resistant finish.
91% Diamant Ultra-Clear Glass: Premium low-iron glass removes the greenish tint found in standard aquariums for true-to-life color reproduction.
45° Mitered Edges & German Silicone: Precision 45-degree joints double the bonding surface area for maximum structural strength and borderless viewing.
Golden Ratio Dimensions: Designed with the aquascaper in mind, UNS tanks move away from standard dimensions by using the Golden Ratio to provide additional front‑to‑back depth, giving your layouts the essential breathing room needed to create true perspective and a sense of scale.
Signature Laser-Etched Branding: Features a clean, laser-etched UNS logo in the glass corner for an authentic finish that will not peel or fade.
Acoustic Leveling Mat Included: Pre-cut dense foam leveling mat absorbs micro-vibrations, levels surface irregularities, and protects against glass stress points.

Frequently Asked Questions
1. How does the Limited Edition Blue UNS 90L differ from the standard version?
This limited edition version incorporates a pre-applied frosted blue background with a satin finish and a heat-fused white bottom panel, as well as a matching white leveling mat, providing a distinct, gallery-ready contrast compared to the completely clear standard model.
2. What livestock is best suited for a 21.3-gallon long aquarium?
The 3-foot horizontal length provides excellent “runway” space for active nano schooling fish (such as Tetras, Rasboras, Danios, or Rainbowfish), Corydoras, hillstream loaches, or large colonies of dwarf shrimp.
3. Why is a leveling mat necessary for rimless aquariums?
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 weight. The included dense foam mat absorbs micro-vibrations and distributes weight evenly across the entire footprint to prevent glass stress cracks.
