The Ultimate Rimless Glass Aquarium Tank

Ultum Nature Systems was the first brand to produce rimless aquariums using ultra high clarity low iron glass with a very unique feature - the 45 degree mitered edge. Unlike traditional rimless aquariums, where all 5 panels of glass are cut with a flat edge then bonded together with clear silicone, the Ultum Nature Systems aquariums take it to the next level.

The mitered edge used by UNS on 4 glass panels allows for a much more seamless joint and requires less silicone to form the corners of an aquarium. This means that not only are the corner edges much cooler to look at, the silicone can be much more precise and cleaned up nicer, which means no globs of leftover dried silicone. A secondary benefit to this is that because the silicone is now angled unlike their flat edged 90 degree counterparts, aquarium maintenance tools such as an algae scraper can clean up against each corner without the worry of accidentally cutting into and degrading the silicone seam overtime, which could lead to potential tank leakage.

Rimless Shallow Glass Aquariums for Aquascaping

Shallow aquariums are low-profile tanks that provide a unique canvas for dynamic hardscape, emergent plant growth, and creative nature-style or Iwagumi aquascapes.
Why Choose a Shallow Tank?
Ultum Nature Systems (UNS) shallow aquariums have become a popular choice for top-down viewing and growing emergent or marginal bog plants in pond-style scapes.
