UNS 45U - 9.3 Gallon Limited Edition Blue Rimless Aquarium

Product Overview

The limited edition UNS 45U Rimless Aquarium reimagines the classic nano tank with design details that elevate your aquascape. Built with the same 91% clarity Diamant glass and signature 45° mitered edges, this version features a frosted blue background with a soft satin finish for added depth and a clean, modern presentation. A heat-fused white bottom offers a refined look while providing a durable, peel-resistant finish built to last.

At under 10 gallons, the UNS 45U is ideal for shrimp, snails, and small schooling species, making it a great fit for desktops, apartments, or compact spaces. The frosted backdrop creates a subtle sense of depth while helping plants, hardscape, and livestock stand out with a polished look. Perfect for hobbyists looking to build a nano aquascape with a little something extra.

Key Features & Benefits

• Frosted Blue Background: A soft, satin-finished frosted blue backdrop adds subtle depth, accentuates green aquatic foliage, 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 45U differ from the standard version?

This limited edition version incorporates a pre-applied frosted blue background with a satin finish, a heat-fused white bottom panel, and a matching white leveling mat, providing a distinct, gallery-ready contrast compared to the completely clear standard model.

2. Why is the UNS 45U one of the most popular nano rimless aquariums?

The 45U hits a "sweet spot" for nano aquascaping: its 9.3-gallon capacity provides greater water volume stability than micro tanks while maintaining a manageable footprint that easily fits on desks, counters, or small stands.

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.
