No, it's not a problem to leave the Sonotube and its plastic "Square Foot" (like these) in the ground forever. Although they will slightly retard the hydration (loss of water) of the concrete mix, the concrete will achieve enough strength in a few days to build upon.Do you need rebar in sonotube?
To support a beam for a residential deck, does a Sonotube pier need any rebar? A.

Depth: Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected. Width: Footings should have a minimum width of 12 inches.How many bags of concrete do I need for a deck of footings?
60 cubic feet when combined with 4 quarts of water. If you're purchasing 80-lb bags of concrete, you'll need 1.66 bags of concrete.
