That is changing the water, not cycling the tank. Go online and read about the nitrogen cycle. You must add an ammonia source (e.g. Cocktail Shrimp, Pure Ammonia).
Here's a basic rundown of the cycle.
Ammonia ---> Nitrite ---> Nitrate
Beneficial Bacteria breaks down fish poop and uneaten fish food. That is ammonia, then the BB turns the ammonia into Nitrite, and the Nitrite into Nitrate. This process will first happen an take anywhere from 2-6 weeks. Once all the elements go to zero, except nitrate, then you add another ammonia source. If that goes down without 24hours, then your tank is cycled.
