UNS 90LA - 21 Gallon Dual AIO Rimless Aquarium

Product Overview

The UNS 90LA Dual AIO is a 21-gallon long rimless aquarium constructed from 8mm ultra-clear glass with an integrated 3-chamber rear filtration system. Its panoramic footprint provides an expansive horizontal canvas perfect for dramatic hardscape layouts and shallow river-style aquascapes. By concealing equipment behind a sleek black acrylic wall, this plug-and-play setup eliminates external hoses and canisters for an unobstructed view in both freshwater planted and nano marine reef setups.

Key Features & Benefits

Panoramic "Long" Footprint: Offers a generous 35-inch length and shallow 11.8-inch height to maximize swimming space and create expansive, layered aquascapes.

91% Diamant Ultra-Clear Glass: Premium low-iron glass eliminates the green tint found in standard aquariums for true-to-life color accuracy.

45° Mitered Edges & German Silicone: Precision 45-degree joints increase bonding surface area for nearly invisible seams and high structural strength.

Hidden Triple-Chamber Filtration: Native rear sump conceals mechanical, biological, and chemical media out of sight.

High-Output Sigma 1800 Pump: Driven by a compact 25W submersible pump with pre-installed hose and an adjustable trumpet nozzle to maintain strong water turnover across the long footprint.

Acoustic Leveling Mat Included: Pre-cut dense foam mat cushions the bottom panel, absorbs micro-vibrations, and prevents stress cracks.
