UNS Ultra Clear Tanks [DUAL AIO]
Product Overview
The Ultum Nature Systems Dual All-In-One (AIO) Ultra Clear Rimless Aquarium Series elevates premium glass tanks by integrating a high-performance, hidden filtration chamber directly into the back frame. Crafted from 91% Clarity Diamant low-iron glass with 45° mitered edges, this plug-and-play aquarium eliminates external canister hoses and equipment clutter while delivering distortion-free, panoramic views. Designed for both freshwater aquascapes and marine reef setups, the Dual AIO line offers a complete rimless system built for long-term stability.
Key Features & Benefits
- 91% Diamant Ultra-Clear Glass: Engineered with premium low-iron glass that eliminates the greenish tint found in standard aquariums for true color accuracy.
- 45° Mitered Edges & German Silicone: Precision-cut 45-degree mitered joints bonded with high-performance German silicone maximize surface contact area for exceptional seam strength.
- Integrated Triple-Chamber Filter: A native back-sump filtration system conceals equipment behind a clean black acrylic wall while delivering mechanical and biological filtration.
- Adjustable Return Flow: Includes a pre-installed submersible powerhead pump with a standard trumpet outflow nozzle to customize water movement for delicate plants or livestock.
- Acoustic Leveling Mat Included: Comes with a pre-cut dense foam leveling mat to absorb micro-vibrations, level minor surface imperfections, and prevent stress cracks.

Filtration System & Chamber Flow
The rear chamber is divided into three distinct stages to ensure mechanical, biological, and chemical filtration purity:
- Stage 1 (Surface Overflow & Mechanical): Water passes through the surface skimmer intake onto the coarse filter sponge, trapping fish waste, plant debris, and floating matter.
- Stage 2 (Biological Media Chamber): Water flows down through the media riser tray housing high-porosity UNS Bio Blocks, cultivating dense colonies of nitrifying bacteria.
- Stage 3 (Return Pump Chamber): Clean water collects in the final chamber, where the submersible powerhead pushes water back into the display tank via the adjustable trumpet nozzle.

Frequently Asked Questions
1. Do I need to buy a separate filter for a UNS Dual AIO tank?
No. The Dual AIO series includes a fully integrated 3-chamber rear filter system equipped with a submersible return pump, mechanical sponge, media tray, and UNS Bio Blocks. You only need to add an aquarium heater and light fixture.
2. Can UNS Dual AIO tanks be used for saltwater reef setups?
Yes. The rear filtration chambers accommodate additional marine filter media, protein skimmers, or small reactors, making these tanks suitable for both nano reef and freshwater aquascapes.
3. Why is a leveling mat necessary for rimless aquariums?
Because rimless glass tanks rest directly on their bottom panel without a plastic frame, even microscopic imperfections on a stand can create pressure points. The included foam leveling mat absorbs vibrations and distributes weight evenly to prevent glass stress cracks.
