UNS 90L - 21.3 Gallon Limited Edition Rimless Aquarium

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 and Important Notes

• Frosted Blue Background: A soft satin-finished frosted blue background adds subtle depth and contrast
• Heat-fused White Bottom: A durable, heat-fused white bottom creates a clean foundation for your aquascape with a peel-resistant finish to maintain its look over time.
  
• 91% Clarity Diamant Glass: The low-iron formula produces transparent, extra-clear glass with minimal residual green color, ensuring your plants, fish, and hardscape are seen with vibrant, natural tones.
  
• 45° Mitered Edges and German Silicone Seams: The 45° precision‑cut mitered edges create tighter, cleaner joints. The increased bonding surface allows the high‑performance German silicone to form stronger seams between panels, resulting in superior structural integrity and a panoramic view.
  
• 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.
