that's the framing I have to use to discuss cycling or results go all over the place. We kick out nitrate, nitrite and only go with what ammonia does after 30 days. We only factor ammonia testing in that thread to cycle, the other two are distracting info
with that as the context, every single cycle passes the same date.
Regarding his nitrate and nitrite I can't answer it accurately, testing ranges just too much and has too many known adulterants for us to use the info. The new school way of cycling is with ammonia behavior and known submersion time frames, this is the great equalizer.
Since nitrite doesn't matter in marine tanks, and nitrate is for algae tuning, that's 2 less test misreads for us to consider.
We can see on any cycling chart that nitrite complies when ammonia complies in a cycling system, somewhere near day 30. that's one of the reasons we landed with ammonia-only cycling in order to make sense of it all.
