I had in, 2 week the ammonia to bee at 3 whit fish food, after the first week i startet to get nitrit
readings, then after two weeks i got nitrat to go up from 12 to 30, then 3 days after that the
ammonia and nitrit got down to 0, it has stayed on 0 in a week now, even then i put the same
quantity fish food in. So it should have cycle right?
