UNS 3N - 2.9 Gallon Ultra Clear Rimless Aquarium
Product Overview
The Ultum Nature Systems (UNS) 3N 2.9 Gallon Ultra Clear Rimless Aquarium delivers a compact, museum-quality canvas perfect for nano aquascaping. Ideal for desktops, countertops, and small living spaces, nano aquariums offer an approachable, low-commitment entry into planted tanks and shrimp keeping.
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.
- Golden Ratio Proportions: Scaled around classic aesthetic proportions to provide enhanced front-to-back depth, offering aquascapers essential room for hardscape perspective and plant layering in a nano footprint.
- Signature Laser-Etched Branding: Features a clean, laser-etched UNS logo in the glass corner for an authentic, permanent finish that won't peel or fade.
- Acoustic Leveling Mat Included: Includes a pre-cut dense foam leveling mat to absorb micro-vibrations, level minor surface imperfections, and prevent structural stress cracks.

Frequently Asked Questions
1. What type of livestock is ideal for a 2.9-gallon nano aquarium?
Due to its compact 2.9-gallon volume, the UNS 3N is best suited for low-bioload nano aquascapes. It also makes an exceptional desktop display for aquatic mosses and slow-growing epiphytic plants like Anubias Nana Petite.
2. Why is a leveling mat necessary for rimless nano aquariums?
Because rimless glass tanks rest directly on their bottom panel without a raised plastic perimeter frame, even microscopic debris or grain of sand on a stand can create concentrated stress points. The included dense foam mat absorbs vibrations and distributes weight evenly across the entire footprint to prevent glass fractures.
3. Can I use a glass lid on the tank?
Yes. Ultum Nature Systems offers precision-cut glass lids (available in Lid + Clip or Flush Fit options) to minimize evaporation and prevent livestock from jumping out.
