I personally always recommend starting with new "dry" sand..
Used sand can be used but you need to clean/rinse it VERY well as its fully of decomposed poop,etc.. from years or whatever of use..
Personally the cost of sand is low enough that rinsing old sand is just not enough of a money saver for me...
I also don't think there is much if any value in "live sand".. From my experiences on systems where I used live sand I had worse initial algae/diatom,etc.. blooms (the normal ugly stages were worse) even though it might have cycled the tank quicker due to whatever bacteria may have been present in that sand..
Nor do you know how long its sat on a shelf in a warehouse so the amount of actual beneficial bacteria in it may be very low..
