Why put a foam layer under my aquarium?

Although our aquariums are not supplied with this, you may see many on the market which are. The idea of having polystyrene or foam under the tank is for the tank to settle on, creating an even or level surface. If the tank is sitting on an un-level surface, it can cause stress and pressure points on the glass that can be invisible until it's too late.

We advise always resting your aquarium on the cabinet it is supplied with, on a flat even surface.
