One more thought on this. How is the tank supported? If it is evenly
distributed with a flat bottom over a large area, that is the consideration.
If, however, the tank is supported by four feet, you may save money and get
a better job with a different approach. I'd pour a deep footing with
sonotubes where the feet are, then pour a standard 4" slab around them for
the rest of the hardware.

It is a flat bottom tank, so the entire bottom of the tank would be on the
pad.
Thanks!

That being the case, 1" would do it as would a couple inches of
gravel but I wouldn't pour less than the standard 3.5" (2 x 4
form) and I do like steel in everything but with even weight
distribution, I doubt it is going anyplace.

Hi Scott,
I did a pad last year for my 2500 gallon water tank; 6" thick with
rebar on 12" spacing both ways. Also put in 12" deep footer around the
perimeter (mine is enclosed with walls and roof). Absolutely no
problems with cracking (yet)

Well, just wait. The rule is that at exactly 23 months, that slab will
disintegrate into tiny marble sized pieces, the rebar will twist in the
wind and the tank will slide over to a 45 degree angle leaking contents
out of the top. That's just how it is.
Kidding of course :)
