UNS 90LA - 21 Gallon Dual AIO Rimless Aquarium

The UNS 90LA is a Long All-In-One (AIO) aquarium that elevates the craftsmanship of standard rimless tanks by integrating a professional-grade filtration system directly into its elongated frame. By combining a panoramic horizontal stage with built-in filtration, this design provides a sweeping field of view, ideal for river-stream scapes and schooling fish, while eliminating the visual clutter of external hoses and canisters. The result is a streamlined, plug-and-play system with high-definition clarity that maximizes horizontal swimming space and creative perspective. The 90LA can be further customized with optional accessories to support a successful freshwater or saltwater ecosystem.

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 clean, 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.
• Triple 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 triple 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 Brick: Serves as biological filtration and provides increased surface area for beneficial bacteria to colonize, resulting in increased biological filtration capacity.
• Power Head Water Pump: The last filtration chamber houses a compact power head water pump, driving the flow of clean water back into the system. The flow can be easily adjusted, and the filter tubing already comes pre-installed.
