How thick should the floor be?

Okay most know about the 210 coming in. I figure a 4 inch concrete floor should be thick enough. Any objections? Work will comence Tuesday morning.

4 inches of concrete is strong enough. Where is this tank going? Basement? second level?

Just an FYI, four inch in standard driveway thickness and garage floor thickness with most city building codes. 6" is used for heavy duty driveways for large equiment and semi trucks. So in reality 4" is more than needed, but that's what I'd go with, after all my tanks are far more important than my car.
