The main challenge is getting api or Red Sea ammonia to validate on second pass of 2ppm added what we already know to occur after day ten wait in these specific conditions with the initial drop already measured and on time
If you had a calibrated seneye meter i wouldn't mind if you triply verified ammonia control, or dosed 2ppm eight times in verification... the system would keep clearing it over and over
Nobody knows yet what the confounds are that make red sea and api 'stick' after multiple ammonia doses and it's simply never an inability to actually clear the test load (when measured digitally)
Every inclination to verify then reverify just in case comes solely from the paradigm of non digital test approximations, which is the last forty years of knowledge about what reef tanks do with waste ammonia control
Variations in test accuracy and perception of those tests, but not the actual cycle ability, is where the doubt training comes from
digital tracking for ammonia control is new, not the majority, a few years established vs 40+ and has opened new understanding about the constant consistency of reef tank cycling. In my opinion it'll take another ten years for the hobby to eliminate cycling doubt from its training process and learn that disease management is where you verify+reverify--only the rise of cheaper/ digital/ competing brands beyond just seneye that can validate one another will bring about this change
I would like to say that owing to the nh4/nh3 interpretation issue plaguing cycling science currently Muk could just re dose some load ammonia and watch for a rise on the cheap kits, then a drop to indicate readiness (but not back to hard zero i.e. the basis of every stuck cycle post on the internet) but the fact remains i have lots of link examples where the second test dose stuck and didn't clear much at all... some were on day sixty of wait.
There are no sixty day cycling charts for any parameter
Basing your cycle on non digital test kits is begging to be trained in doubt. Gimme ten more years then check this thread for validity in claims
If you dose again and it clears that's great, it's a good kit and a good readers technique.
But if you dose again and it sticks, that specifically does not mean your cycle is stalled, there's over two million instances of false stalls on Google and they're comprised of api and red sea kits but never a calibrated digital kit already showing one verified drop, after day ten, using this strain of bacteria
*i believe fully a dead bottle won't clear a big load by day ten. This isn't a dead bottle though, we can already see in the posted results + timing at hand.
