Fish produce amonia, that's why to fishless cycle a tank you need to add amonia. Fish-in cycling can be hard on fish, and is a lot slower than fishless. (I'm still cycling my twenty technicaly. My nitrates and nitrites are still kinna up there.)
You need to do a water change at LEAST weekly, probably more. And you need a test kit, I reccomend the api master kit, it's at petco or petsmart.
It will cycle, but it takes longer and kinna hurts the fish.
