I'm about a week in my fish-in cycle. I've been testing everyday and the PH has been 8.2 and ammonia has been between .25-.5. Nititres and nitrates have been 0. Tested this morning and ammonia was .25, nitrites 0 but my PH is 8.4 and nitrates is 5. I'm confused, I thought nitrites were supposed to show up before nitrates?
