All you need is "pure ammonia" and some seasoned items (if you have some) and your ready to go.
Ammonia is your food for your beneficial bacteria to grow. If possible, by dropping the level of your water this will create a bigger splash and more O2
for your bacteria. Add additional airstone and slowly move your water temp up to 84. All these things will help your bacteria grow and mulitply.
Good choice on the fishless cycling!!
