The Ultum Nature Systems Dual All-In-One 90LA Peninsula Aquarium is the largest model in the Dual AIO collection, offering a 21-gallon rimless peninsula-style display. Designed for aquarists who want more room for creativity, this aquarium combines panoramic viewing angles, low-iron glass clarity, and an integrated triple-chamber filtration system to deliver a premium aquascaping or reef-keeping experience.
Sleek Peninsula Layout
The 90LA’s peninsula design creates a striking focal point with multiple viewing perspectives, making it perfect for placement on desks, counters, or as a centerpiece in open spaces. Constructed with 91% clarity low-iron Diamant glass, 45° precision-cut mitered edges, and black silicone seams, it offers maximum durability and an elegant, modern finish.
Built-In Triple-Chamber Filtration
Like the rest of the Dual AIO series, the UNS 90LA includes a rear filtration system to simplify setup and reduce clutter:
-
Chamber 1: Mechanical sponge removes debris and waste.
-
Chamber 2: UNS Bio Bricks provide biological stability for healthy water conditions.
-
Chamber 3: Submersible pump with adjustable flow ensures reliable water movement.
This hidden filter design keeps equipment out of sight while maintaining pristine water clarity.
Freshwater & Saltwater Compatible
Whether you’re planning a lush freshwater aquascape or a compact marine reef tank, the UNS 90LA is built for both environments. With optional add-ons including the media tower, refugium module, protein skimmer, filter sock kit, and auto top-off system, you can customise the tank to meet your exact needs.
