Key Features & Benefits
- 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-cut 45-degree mitered joints double the bonding surface area for high-performance German clear silicone, forming stronger seams.
- Integrated Quadruple-Chamber Filtration: Native rear sump conceals your mechanical, biological, and chemical filtration out of sight across four dedicated chambers.
- Customizable Dual Flow Control: Includes two submersible return pumps with pre-installed tubing and two adjustable trumpet nozzles to direct water movement.
- 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 75A Dual AIO aquarium?
No. The 75A Dual AIO includes a complete 4-chamber rear filtration system equipped with two submersible return pumps, mechanical sponges, media riser trays, and eight UNS Bio Blocks. You only need to add an aquarium heater and light fixture.
2. Can I use the UNS 75A 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 Dual AIO Protein Skimmer or custom media filter socks, making it an excellent plug-and-play platform for 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. The included foam leveling mat absorbs micro-vibrations and distributes weight evenly to prevent stress cracks.
