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 Triple-Chamber Filtration: Native rear sump conceals your mechanical, biological, and chemical filtration out of sight.
Customizable Flow Control: Includes a submersible return pump with pre-installed tubing and an adjustable trumpet nozzle 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 45A Dual AIO aquarium?
No. The 45A Dual AIO includes a complete 3-chamber rear filtration system equipped with a 10W 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 45A 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 nano 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.

Looks Great. Doesn't work.
"Looks great out of the box. Problem #1 Provided pump didn't work when I plugged it in first time Asked Buce about this. Was told to purchase another one rather than them sending a replacement. Purchased another pump. Spent hours trying to get the flow just right. Gave up on the whole all on one and just slapped a HOB on this tank. Wish I had skipped to the end where I just didn't use the AIO feature. It's a shame for something that looks so good, but it doesn't do what a filter should do. . . move water."

Tank came scratched
"Tank showed up with the rear glass filter lid broke. Upon further inspection the inside of the tank had scratches from the accessory box bouncing around inside the tank during shipping. The claim process seems weird as I don’t have the original box it was shipped in. I guess next time I’ll take a ton of pictures before throwing the box away. Let’s see if they make it right."

Almost perfect
"This little tank has worked great as a desktop aquarium to scape in. The AIO compartments are a little tight, but still have enough room for sufficient media and components. The tank as a whole, definitely meets the reputation of other UNS aquariums. Crystal clear glass, and high quality craftsmanship. My only complaint, and the reason for 4 stars, is that the USB power adapter shorted out about a week into use. I was able to find a more robust replacement that has not had any issues since, but I was a little frustrated to find the pump not running after a short period of use."

Good AIO but not perfect.
"This is a really nice tank. I love the ease of an AIO but they aren’t without their limitations. I wished they would have kept the old style and skipped this peninsula layout. With the peninsula the filter area is very cramped especially for people with bigger hands. I am not a huge fan of the viewing perspective of this tank. I wish I would have went with a different size a style tank. I have been very limited in how to scape this tank. Build quality is top notch though."

Hello is this a Side-Orientation tank??? Because the previous 45A model was a Front-Orientation.
Hello! Thank you for your interest. That is correct, the new improved UNS 45A model filter is on the side of the tank, but can be switched too either sides. If there is anything else we can assist you, please feel free to email us at support@buceplant.com. Thank you, Team Buce Plant
