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:

  1. 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.
  2. 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.
  3. 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.

Reviews

"Cool tank. Good build quality and came with everything needed."

— Tanner (5/5)

Aesthetics nice, function poor

"The high intake requires a high water flow. Nothing can obstruct the intake - no floating plants and especially not the filter guard sold separately, which will cause the main chamber to overflow and the reservoir/filter chamber to run too low for the pump. The glass chamber lid is super thin and fragile and breaks shockingly easily, requiring purchase of an acrylic one. The tank does not come with a lid, which you will need to buy and because you need to keep the water level fairly high, there is still splashing that runs down the side of the tank. MAYBE this would be a good tank for a low flow singe betta, but otherwise poor engineering. When I contacted Buce with these problems, received no resolution beyond a $15 coupon for another product. Very disappointed."

— Julie W. (2/5)

The 90LA is Built!

"This thing is not cheaply made. The weight. And quality is amazing. I bought 180 dollar tank from this awful american brand. The product was awful. Spending twice the amount got me 4 times more. So happy with my purchase"

— TK (5/5)

Great tank

"Love the tank so far! I just got it set up and planted last night and it’s looking great. My betta (Tunç) should be moving in very soon."

— Zack B. (5/5)

Hate the hum, baby.

"I purchased an AIO from Buce. The noise drove me nuts. Tried everything to dampen the incessant hum. Finally bought a DC pump. That solved the problem. Buce should upgrade their AIOs with DC powered pumps."

— Aquascaper (1/5)

"Nice tank"

— Kosin (5/5)

Couldnt ask for better

"Size is perfect, setup was super easy. I love being able to hide all equipment in the filter chambers. Hearter and CO2 both fit back there great and there is plenty of space for additional Bio media."

— Peter M. (5/5)

Is the filtration system in these dual AIO tanks sufficient for planted tanks with aquatic animals as well?
Hello Chris, thank you for your question. We'd be happy to assist you. The UNS dual AIO tanks generally come equipped with built-in filtration systems that are designed to provide adequate filtration for planted tanks with aquatic animals. These AIO systems often include compartments for mechanical, chemical, and biological filtration media. However, the sufficiency of the filtration system depends on various factors, including the tank size, the specific needs of the aquatic plants and animals you plan to keep, and the stocking density of the tank. It's essential to consider the specific requirements of your planted tank, such as the type of plants, the size and species of aquatic animals, and the overall bioload. We hope this information helps! If there is any other questions or concerns, please feel free to email us at support@buceplant.com. Thank you, Team Buce Plant
