When I did my first cycle that's exactly what I did. I got some dr. Tim's amonia chloride so that I could control exactly how much I wanted in the tank. Unlike if you throw a shrimp or fish food in.Yeah, listen to what Flagg said. When Ammonia and Nitrites are zero, you'll know your ANN cycle bacteria is up and running. Check it now, and Ammonia should be above zero.
Typically there is enough dead stuff on the rocks to spike ammonia, and ironically you need some otherwise the ammonia eating bacteria can't thrive, and produce nitrite for the nitrite eating bacteria.
Some people put in some fish food flakes just to kick start the cycle. Some people even put in some ammonia!!
