I see your answer as this
You implied two different processes above from the same bottle, that has to be factored. The ability to cycle is not the same as competition against invaders. There are genetic based studies verifying the cycling bacteria we are able to ship around in water.
No form of dino control beats 20% efficacy...and using bottle bac against them is the same. it is harmless to try, if it doesn't work you didn't harm anything.
Contrast that against pH jacking, also reported a way to beat dinos. Owing to the 20% rule, as any large dino cure thread is mostly misses 80%, I never liked messing with critical tank params with the best likelihood of it not working (or threads would reverse outcomes, cure 80% of posters)
Each must have their own go at dinos. Given my research it would be
Massive tank cleaning, no dinos, hard work clean out.
Oversized uv sterilizer, gross oversize.
Blackout
Peroxide
Squirt some mb7 not a harm.
Those five are what I'd do. If it helps to know, and prevent, the sole cause of all dino tanks is purposefully importing them, even fish bring them across tanks. Anything traded is a vector. Quarantine is how you detect the DNA (manifests as aggregate community invasion) eradicate it, then use those items dino free. That's helpful to know because it reveals dino transmission among tanks as not haphazard, but purposefully done by the keeper. That rule also allows one to purposefully exclude them as well, quarantine works.
The best results currently seen are by using dino xal among retail dosers. I bet dinoxal is curing over 20% all threads considered. Also, 4/10 claimed Dino invasions sans pics are just cyano invasions caused entirely oppositely.
Plenty of people used mb7 to battle cyano and won. I feel it's legit, if bio counter attacks are the chosen mode. We're all trying for better odds.
