Just a thought,

The problem with placing it on crushed rock is that the edge is so thin it will eventually sink in. If there is any softness in the base course the sinking can happen pretty fast. That is the problem I have now. The original builder didn't pay attention to the ground and placed the tank on an area that contained debris from the land clearing. As a result the tank has sunk several inches on one side in a period of 3 years. I would like to avoid that in the future and not knowing for sure what is under the ground here I wanted some insurance against future problems.
I do realize it requires special care in construction and use of rebar to make the ring strong enough.
No matter how thin you slice it, its still balony.
