How much sand do you add underneath the tile?... a thin layer is all I can find online and everyone's opinions of thin could be different. Any one have a guess in mm/cm/in?
Also, does it matter what type of sand? (aquarium sand/kids sandbox sand?)

Really you just need enough to hold the tiles in place. 1/8", 1/4" either is fine. As long as you have a thermostat to regulate ground temps you should be good. I would buy kids play sand from a local hardware store. You can probably get a 50lb bag for 1/2 the price of what you would get in a 10lb bag of "reptile" sand.
