Accumulator tank in earth cellar. Do I need to cast?

Planning to place a 500-liter buffer tank in the earth cellar, wall to wall with the boiler room. The floor consists of loose gravel and soil, quite dry. Initially, I was just thinking of placing the tank on a sheet of ground insulation. Would that suffice, or should I pour 5cm of concrete? It would then involve about 80 liters of concrete. Does the substrate need to be packed somehow? I have only cast a little under the wood stove before, it was fun and turned out well, but otherwise, I don't know much about casting. What I used then was fast-setting fine self-leveling compound.

Father-in-law thought that 7cm thick concrete was sufficient, is that so? And what should be used to easily remove air from the concrete?
