The OptiClear low-iron glass reduces iron content, which minimizes greenish tint and improves clarity, resulting in more accurate color representation and a brighter view of the aquatic environment.
Can this tank be used for a planted tank with carpet plants?
Yes, the tank’s dimensions and depth allow for small planted setups with carpet plants or mid-ground stems. It provides enough space for root development and plant growth in a minimalist layout.
Is the tank stable on a desk or countertop?
The low-profile design with polished edges ensures a stable and secure fit on desks, shelves, or countertops. It is built to resist tipping even when filled with water and small decorations.

I bought this for my office desk and it fits perfectly. The clarity is outstanding—my shrimp look vibrant and the plants look natural. The shallow depth makes it easy to place without taking up much space. Great for a small setup.
