In order for the cycle to start you need to get ammonia in the tank. When doing a fishless cycle you can add fish food or they have these starter kits which provide the ammonia (i believe). You'll also have to get test kits to test your water if you haven't gotten them yet (especially ammonia, nitrite and nitrate but you'll also want to test pH) This is just the basics..I'm sure someone will come along that can give you the specifics. And welcome to the forum!!
