here's how to tell if its cycled, yes moving a decent chunk of live rock from one tank to another does not kill the bacteria:
did your rock from from another reef or holding vat that had coralline, animals, fish preferably swimming in it
if so you skip cycled, which is what macna conventions do to start 400 reefs on time for 30 years.
some people call dry rock live, because it eventually will be, so we need to know its simple origin.
you don't add ammonia or bottle bac to live rock, because you pay for skip cycle rock if its live.
bottle bac and ammonia can go into suspect source rock, dry, unknown etc. but to add things to a true live rock skip transfer is total reefing malpractice heh.
