Cycling is the process of colonizing the beneficial bacteria we need in a tank's filter to keep the fish happy and healthy. You begin by getting some pure ammonia and an API Freshwater Master Test Kit. Then, you dose 4ppm of ammonia (measured with your test kit). Everytime the ammonia goes down, you dose more and check on your Nitrites. Nitrites eat ammonia. Then, another bacteria will come along and eat your nitrites, producing waste that we see as Nitrates. Nitrates aren't harmful to your fish in small amounts (under 20ppm). Once the ammonia is being converted into nitrates in 24 hours (make sure three times) you can do a water change to bring the nitrates down and begin adding fish a little at a time.
