UNS 30C - 7.1 Gallon Ultra Clear Rimless Aquarium

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.

Cube tanks offer a symmetrical canvas designed to center your focal point. With equal dimensions on all sides, the format naturally draws the eye inward, perfect for intricate hardscapes, shrimp colonies, or specimen fish like Bettas. Whether as a standalone piece or a gallery-style row, the Cube provides a clean, immersive window into your layout.

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.
