just joking I was not wanting that lol
getting off that wheel occasionally is so calming
2 mos= not much of an endurance test
but 14 mos would be, since you have nicely calibrated testing procedures for bacterial starvation assessment, in my opinion you should run some experiments that test out the longer waits and let us know.
there's a void in all reef aquarium science for that info. Nobody can tell us how long cycled bacteria remain viable in home settings when not directly fed by humans, it hasn't been studied yet in home/hobby settings. if someone on google scholar once tested it in a university setting on a cold dead steel slide, that isn't the same context.
the context is knurled rock from a reef tank, typical reef tank surface area rock plus inclusions from a completed and verified common reef tank cycle. there's a void for that specific info
with a simple paint bucket test setup you can have a side tank to do cycling experiments with.
