Description
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.

Frequently Asked Questions
1. Do I need a separate filter for the UNS 90LA Dual AIO aquarium?
No. The 90LA Dual AIO includes a complete 3-chamber rear filtration system equipped with a high-output 25W return pump, mechanical sponge, media riser tray, and two UNS Bio Blocks. You only need to add an aquarium heater and light fixture.
2. Can I use the UNS 90LA Dual AIO for a marine or saltwater reef tank?
Yes. The rear filtration chambers are dimensioned to house marine-specific equipment, such as the UNS Mini Protein Skimmer or custom media towers, making it an excellent plug-and-play platform for long shallow reef aquariums.
3. Why is a leveling mat necessary for rimless aquariums?
Because rimless glass tanks rest directly on their bottom panel without a raised plastic frame, microscopic imperfections or sand grains on a stand can create concentrated stress points under weight. The included foam leveling mat absorbs micro-vibrations and distributes weight evenly to prevent stress cracks.
