I'm doing a fishless cycle. About a week ago i noticed nitrites for the first time. They were .25 with api test kit. Ammonia slowly started to go down from 3-4 and it got to about .5-1.0 so i added a little more to bring it up. Brought it back up to about 3-4. Now it's at 2.0. My nitrites are up to at least 5.0, if not more, though so I thought my ammonia should be getting eliminated in 24 hours by now. Is this normal? I thought once nitrites got that high ammonia is eliminated in a day.
