that's precisely why I wanted to get off testing for it unless you buy a seneye, and that's using $$ to measure a param we can always predict without a test kit. Not trying to flood you with a large link, but this thread thoroughly describes your ammonia level based on seven weeks underwater.
submersion timing is so reliable, we have a 17 page
no test cycling thread. we have collections of 8 ppm persistent ammonia for 7 weeks which turned out not to have any ammonia the whole time.
You can skip your cycle. Ive been reefing online for twenty years and have never waited one second for a tank to cycle, because I buy rocks that are already cycled and move them home. Here's two: https://www.reef2reef.com/threads/octo-high-end-sps-skip-cycle-build.713256/...

the second example in the thread is a disagreement between API and Salifert, and they're both wrong lol.
Ammonia testing without seneye is a waste of time, and paying for a seneye is like paying for a $250 oil change indicator on my car. I can also just go off 3 k miles and call it good. we do that with # of days underwater and it cannot fail, we show (along with all google cycling charts, none are seven weeks in duration for a reason)
all the tanks in there, both dry and live rock skip cycles, done without a single test of ammonia. People still provide the tests anyway to calibrate our readings claimed, and the tests always come back as predicted= with a false sustained low level reading.
Post pics of your tank
its certain your tank is already cycled due to number of days underwater.
Any further ammonia testing is only to discover if a dead fish is in the tank...you can build an accessible tank where a carcass can't hide, then still not need ammonia for the rest of the tank.
the top two unneeded tests in reefing are in order: nitrite then ammonia.
there's a part on page one called cycle umpire, that whole section is this formula: find a stalled cycle thread. discern if its been wet longer than thirty days. be the only one to call the cycle done and leave lol.
you can tell by the # of tanks we turn out not dead, we're onto something special. we are free from getting ripped off.
