certainly do not test for nitrite here it will cause confusion. at fifteen days this cycle is done, you can already see the wheels in motion, and nitrite is neutral in all cycles including this one.
the testing challenges mentioned to you regarding non digital gear dont just stop at nitrite, they include it, and stated nitrite levels are not accepted as accurate anymore than stated nitrate levels are accepted as accurate in comparison threads.
*even when testing nitrate at two-three months, to give time for nitrite to zero out, that reading still is not accepted as accurate per any comparison thread. it lines up on paper but not in titration testing using api and cheap gear like it.
nitrite and nitrate are never needed to be known in calling any cycle done.
we have tanks out in the general forum that run zero nitrate yet carry fish and corals, and they're cycled.
if you track your cycle out using anything other than # of days underwater, expect hesitation, fear of incomplete cycle, and buying more bottle bac.
or on day fifteen which you're probably already at anyway, you can just reef and it will line up as all cycles did here.
Team how many times did we need to know your alkalinity to turn out cycles ready here with fish or your ph or any other param if you have water, and time depending on the boosters used, you get a full complete cycle and not a partial one. Someone update the cycling rules for the hobby with...

in that thread, every reef tank gets a specific safe start date based on description. yours is day fifteen underwater.
