In-store pickup in Laval only — this tank does not ship.

The first question we are asked is about the actual volume. According to the technical sheet published by Ultum Nature Systems, the UNS 150U aquarium measures 150 x 60 x 60 cm (59.05 x 23.62 x 23.62 inches) and holds 540 L, or 142.6 US gallons, with a glass thickness of 15 mm. This is the second largest size in Ultum Nature Systems' rimless range, just below the 180U.

Glass chosen for what is not seen

Ultum Nature Systems describes the glass of the UNS 150U as low-iron, Diamant type, with 91% clarity. Concretely, the green tint seen in the edge of ordinary glass almost completely disappears. Over 60 cm (23.62 inches) of height, this matters: the thicker the glass, the more residual color accumulates, and a 15 mm panel is among the thickest installed in home aquariums. It is precisely on a tank of this size that the difference is visible.

Edges cut at 45 degrees

The panels of the UNS 150U aquarium are mitered at 45 degrees before being glued — Ultum Nature Systems refers to "45° precision cut mitered edges" on its official page. The silicone joint is located in the corner rather than running on the surface: instead of a black strip along the entire height of the corner, only a fine edge remains. The UNS 150U also bears the laser-engraved logo that serves as a mark of authenticity from this manufacturer, and a black leveling mat is supplied with the tank.
