I am pouring some 8" pier footings with sonotubes to support a deck. They will go down 4' into sand. Do I need to use bigfoot footings, or can I just pour my own 12" square 6" deep footings at the bottom of the hole right over the sand? I plan on securing the piers to the footings with rebar. Thanks,

Sand? If you are in Florida the footing has to be 18" x 18" x 18" cube. (I just did this under a permit) It has more to do with uplift than down load.
This falls under the ever popular "check local regulations", as it is real hard to tell over the 'net.
Pier footing for a lake? ocean? river? Weight of finished product? frost/freeze?
We are not mind readers.
WAG 4 inches into the ground on dry land would not be enough
