If I was going to build a 6' high free-floating 12'x 12' square deck (no stairs), using 6x6 posts, how far apart should I put the Titan Deck Foot units?

6' Spacing is A Rule of Thumb by: Editor-Rich Bergman
The general rule of thumb is no more than 6' apart but that is not because the anchor material can't handle more. It is because at a minimum of 50lbs/sqft for a deck (live and dead load) it works out to 1800 lbs for a 6'x6' tributary area.
And 1800 psf is about average for most soil. Softer soil would require closer footing spacing. See our calculator here: Footing Load Calculator
For a 12' square deck you would need 9 footings. Three beams with three footings. But check our calculator to see if the middle beam will need one more if your soil bearing capacity is lower than average.
I won an inflatable 6 person inter hot tub. I have a large deck. 12x 20 on both sides of the house. With a header to the house and the deck was built 6
I'm putting a swim spa into an inground concrete bunker and will build a deck around it. I have been advised to keep the deck joists a minimum of 6 inches
