Pretty much any play sand will do. As Nilet said, clean it well which is pretty much just putting a couple of pounds in a pail, blast it with the hose to get it well stirred up and pouring off the crap. If you have a square pail it is easier as pouring it off of a flat opening allows the flow to be spread out and less likely to have it just pouring out sand that you can use. I did this about 15 times then dump into another pail and repeat for the next load.

Putting it in the tank is definitely an empty and start over plan. If you want to do it quickly you can put the sand in wet, fill tank to about half, plant and decorate then siphon off the cloudy water and refill VERY slowly. Even though you've removed most of the silty stuff there is always more to stir up.

I used 18Kg for a 30" x 12" tank to an average of 2" depth.

Okay my large tank is 36 by 20 by 12.5 how much should I use? I would also be filling my 36 by 19 by 12.5 as well. So I have between all my tanks 90 gallons to fill from 2.5 gals to 38 gals

Consider that a bag yields about 700 cubic inches of sand and your tanks are 450 square inches in bottom area... two inches for two tanks is 1800 cubes so 3 bags will give you a little extra to play with. I'm undershooting the yield so two bags might be OK depending on how deep you want to go. I'd just do one tank first and start out with two bags... see how much more you need based on that.
