1. Why select a long (45L) nano tank over a standard cube aquarium?
The UNS 45L features an extended 17.72-inch length that provides a wider horizontal viewing angle and greater swimming distance for nano livestock. This footprint is especially popular for riverbed aquascapes, moss walls, and Iwagumi layouts that benefit from horizontal symmetry.
2. Why is a leveling mat necessary for rimless aquariums?
Because rimless glass tanks rest directly on their bottom panel without a raised plastic perimeter frame, even microscopic debris or sand grains on a stand can create concentrated stress points. The included foam leveling mat absorbs vibrations and distributes weight evenly across the entire footprint to prevent glass stress cracks.
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.
