whats fun about the new way of cycling is we're able to discern start dates vs unspecified wait times...thats the old way which is indeed safe by default
but nowadays (or at least before covid) there were marine conventions, we had to get 500 reefs to start all on a friday, without variance.
enter new cycle science which names the ready date, before the setup, without having to test for anything (its all submersion date timing + known boosters already known in the industry)
there are also home moves, how to get to new home B and skip the cycle or time a new one, to meet up with a bunch of new corals and fish and not kill them. thats new cycling science, we prep the tank for the start date and it complies, it doesnt fail to comply
theres several more times we need a known ready date, but that shows the most common.
