I can't find any ammonia near me either. I used to just pee in the tank until I read SH's post on what is actually in human pee. Didn't seem like a very good idea to continue using that method. I am setting up a tank right now, I guess I will just use bio spira to cycle it. It's not that expensive though. Shouldn't run you more than $70 for a tank of your size.
