The 5 Best Plastic cube Water tanks (2023 reviews)

The landen plastic cube water tank's material feels more premium than its price would suggest. This is a very cool terrarium like multi habitat aquarium. It comes in a wooden packing crate that is taller than the tank, but not much larger in the other dimensions. The low iron ultra-white edge glass and side window glass transmittance of more than 91% will give you a general crystal feeling. It is used to remove algae on the glass. The glass is thick and will definitely support the water pressure exuded on the walls.

The tank is well packaged, the glass is very clearly low iron, and sufficiently thick for its 225L capacity. It is very clean and transparency is neat so you can even see through the bond side to the other side. The aquarium itself is very nice, no extra silicons and very clear. It can be used in food containers.

Why We Like This:

Beveled edges all around and the silicon work is really nice
High-res glass that is very clear
Lot of satisfied buyers
