Ultum Nature Systems Ultra Clear rimless tanks are designed to vanish. 91% clarity Diamant glass provides a high-definition view of every aquascape without the green tint of standard tanks. Signature 45° mitered edges create nearly invisible joints, erasing the distraction of glass overlaps. Discover a rimless aquarium designed by scapers, for scapers, where every detail is built to elevate your vision.

The UNS L line's elongated dimensions can help aquascapers achieve a greater sense of horizontal scale and perspective. The 90L's footprint is perfect for creating sweeping Iwagumi styles or river-stream scapes that require additional room. Beyond its aesthetic benefits, increased swimming space makes it an ideal choice for nano species that require more "runway" room, such as schooling tetras, rasboras, or fast-moving shrimp.

Key Features and Benefits

• 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.
