Few bucks for dr tims ammonium chloride and we w be set for the test. I think it can pass a directed oxidation test but it has to be calibrated with three pics above from post #2 to make the tester work.
if it can’t, then you’ve input no other marine bac sources and the bottle bac was dead or expired. It’s prudent to test ammonia the right way before adding life.
change water first, export rotting waste, start new AC test on clean tank water, not the current wastewater.
i bet you’ll even see some nitrates from AC usage, if the bottle bac was alive when used, which is likely. Killing bacteria in a liquid solution sitting in a room is very very hard to do
