Ultum Nature Systems Ultra Clear rimless tanks are designed to vanish. Featuring 91% clarity Diamant glass, these enclosures eliminate the green tint of traditional tanks for a high-definition view of every aquascape. 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.

By prioritizing a wider, horizontal space over height, shallow tanks provide an expansive open canvas ideal for creative scaping experiments. Whether you are designing a classic Iwagumi layout, a lush nature-style pond, or a hybrid paludarium with emergent growth, the shallow format allows for intense light penetration and an immersive, top-down viewing experience that deeper tanks cannot replicate.

Key Features and Important Notes

  • 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.
