Ammonia for fishless cycle

[basstracker_v16]

Greets all.

Getting ready to set up my son's 15g soon. Wanna try this fishless cycle method
but not sure about the ammonia. I live in the Columbus Ohio area and we have
a Kroger, Mijer, Walmart, Sams Club. The mijer brand says it has coloring and
fragrence in it. Did the "shake" thingy to test for bubbles didnt see any.

So, question is, who has used ammonia and what brand did you use?
