UNS 75A - 40.1 Gallon Dual AIO Rimless Aquarium

The Ultum Nature Systems Dual All‑In‑One (AIO) series elevates the craftsmanship of standard rimless tanks by integrating a powerful, professional‑grade filtration system directly into the frame. This design eliminates the visual clutter of external hoses and canisters, providing a streamlined, plug-and-play aquarium with high-definition clarity. The Dual All-In-One line can be customized with optional accessories to support a successful freshwater or saltwater aquarium setup.

Key Features and Benefits

The Ultum Nature Systems line of Dual All-In-One Tanks comes with everything necessary for a solid foundation. Each tank includes a standard trumpet outflow. 

• UNS Rimless Tank: Constructed with 91% Clarity Diamant glass, a low-iron formula that virtually eliminates the "green tint" found in standard glass. 45° mitered edges provide superior structural strength and a seamless, panoramic aesthetic. Every seam is bonded with high-performance German silicone, engineered for durability and a minimalist, unobtrusive finish.
• Leveling Mat: Specifically designed to support and stabilize the aquarium's weight while protecting against glass fissures and cracks, ensuring overall structural integrity and resilience.
• Quadruple Chamber Internal Filter: A native, fully-integrated internal filtration system that eliminates the need for more equipment, which can detract from the beauty of the aquascape. Features internal filtration chambers that effectively screen out debris.
• Coarse Aquarium Sponge: Serves as mechanical filtration and occupies the first filtration chamber. Prevents fish waste and plant matter from clogging up the other chambers responsible for screening out finer debris particles.
• UNS Bio Block: Serves as biological filtration and provides increased surface area for beneficial bacteria to colonize, resulting in increased biological filtration capacity.
