The changing cycling rules are redeeming api I can see.
example- 1991: any ammonia detected means the cycle is broken, stuck, continuing, not done, and your tank is likely going to die soon unless you buy something or take a decisive action
it doesn’t matter if you convert the reading to nh3 like the directions say, what only matters is if the initial reading says anything above hard yellow zero.
Animals in this water are in pain if there’s anything but hard yellow zero reading for their water
therefore, api‘s known propensity for .25-.5 reading in tanks (caused by myriad subtleties in the kits and test takers and room lighting and angle of dropper and subjectivity interpretation / name the cause it doesn’t matter this is what everyone but the most exacting chemists can expect to see) was 1000% interpreted to mean the tank wasn’t handling ammonia. This is every stuck cycle post ever made to the internet we can search on the goog
vs
2023, years after digital seneye meters came online and thousands of uploads are on the web for searching:
conversion to nh3 matters, context matters, and stocked / post cycle reef tanks don’t run zero ammonia
ergo, the ten million .25-.5 api tests ran on stocked tanks as nh4 were reading rather correctly given the context of the setups AND the natural variations test takers and the kit itself have inherently. No panic is needed in 99.99% of cases, given the rule that reef tanks don’t run zero ammonia to have detected some with api only confirms what we expect now that precision digital test kits have been telling us that since they came online for the hobby (mind stream in ~2013 and seneye thereabouts…mindstream is defunct and seneye continues strong)
the changing rules in cycling that sellers of bottle bac chose not to tell us matters big time in hating or loving api (they who are uninformed will buy our bottles of bacteria redundantly until the end of time, doubt in cycling equals strong sales for the retail
market)
