Are 2x6 strong enough for deck joists?
2x6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Most decking is not strong enough to support longer spans than 16". Some builders reduce joist spacing to 12" on center to strengthen the deck frame or to increase maximum allowable joist spans. via

A single SPF#2, 9' x 2x4 that's restrained by sheathing or blocking can support 1820 lbs and a similar 2x6 that's not restrained can support 7061 lbs. A double 2x4 is only half the weight of a single 2x6. via
How many footings do I need for a 12x16 deck?
A standard deck will need four footings parallel to the house, but they will need to be temporarily braced by 6 inch-by-6 inch posts.

Use a sledgehammer or a pry bar to force the bottom of the new joist along the mudsill and center support beam of the floor system (or the opposite mudsill on short spans) until it's flat against the existing joist. Nail the new joist to the existing joist with two rows of 10d to 16d nails spaced 6 in. via
How do you strengthen a 2x6 floor joist?
If the floor is bouncy but the joists are not sagging, the simplest fix is to reinforce the joists by installing additional joists adjacent to the original ones. Called “sistering,” this is done from beneath the floor in the crawl space. New two-by-six joists are cut to fit snugly beside the old ones. via

Can I use deck pier blocks instead of footings?
Pier blocks can be used instead of footings for a ground-level deck not requiring permits. Any decks higher than 24” require concrete piles 10” in diameter and 48” below grade. These footing size requirements are to ensure enough soil bearing to prevent the joist from sinking in the ground. via
