Simplicity aquarium Mi Mat
The Hugo Kamishi MiMat is designed to fit under the simplicity range of aquariums but can be used under any others the same size or cut to size.
MiMats are used to ensure the surface you place your aquarium on is as flat as possible to avoid stress on certain parts of the aquarium which could cause cracks. Even if you are using a cabinet recommended by the supplier a mat is a great option to add just to be on the safe side
There is a mat for every size of the Simplicity aquariums.
