here is the #1 way api does not work well: on the wastewater sample of a tank after dosing large amounts of ammonia.
your first post here is that mode. we've done opposite as calibration.
what you want to know is if the bacteria you've provided are adhered to rocks, and functional, before spending $ on more bac with no where to attach. taking any wastewater sample to the LFS for alternate testing is still that mode above.
the end result of the test coming up is proof your whole tank is ready, after a water change, to begin now.
