When I cycled my tank, I actually did a fish cycle. I used a few guppies and did a lot of testing. Basically I just kept watching the levels until it was over. I find fish cycling is faster than the ammonia but I've seen people cycle faster with ammonia. I also use them cycling bottles you can buy. I honestly don't know if they work or not but I still use it as it causes no harm. If you do decide on a fish cycle, just get ready to test about 2-3 times per day.
