you need pure ammonia or some raw shrimp at the grocery to supply ammonia. you need a test kit also. if you decide on liquid ammonia, you should get the ammonia up to 4ppm and then every time it drops add more till you get 4. once your tank can get to 0-ammo, 0-nitrites, and a showing of nitrates you'll be cycled. API test kit is what i reccomend for a test kit. with the shrimp you just get some pantyhose and put a shrimp in the pantyhose and just hang the shrimp into the tank and wait till you get 0, 0, and a showing of nitrates. getting some substrate or filter media from an established tank will help speed this up.
