Product Overview
The UNS 90P 48.1 Gallon Ultra Clear Rimless Aquarium offers a popular medium-large footprint for aquascaping and reef displays. Crafted from 91% Clarity Diamant low-iron glass with extra-thick 10mm panels and precision 45° mitered edges, this enclosure eliminates greenish glass distortion to deliver a high-definition window into your living underwater layout.
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: Designed around classic aesthetic proportions with a generous 17.71" depth, giving aquascapers essential room to build complex hardscape rockwork, substrate slopes, and plant depth of field.
-
Signature Laser-Etched Branding: Features a clean, laser-etched UNS logo in the glass corner for an authentic, museum-quality finish that will not 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 under heavy load.

Frequently Asked Questions
1. Why is a leveling mat mandatory for a 48.1-gallon rimless tank?
A filled 48.1-gallon aquarium weighs over 450 lbs when accounting for water, stone, and substrate. Because rimless glass tanks rest directly on their base panel without a raised plastic perimeter frame, even a microscopic grain of sand on a stand can create concentrated stress points under that weight. The included dense foam mat absorbs micro-imperfections and distributes weight evenly across the entire footprint to prevent glass stress cracks.
2. How do 45° mitered edges improve structural integrity on medium-large tanks?
Standard flat-edge joints butt together at 90 degrees, leaving a narrower corner seam. Precision 45° mitered edges double the contact surface area available for silicone bonding, resulting in a significantly stronger structural seam required to safely hold large volumes of water.
