that system is already cycled, see the growths on the lr
that signifies end of cycle, months ago.
what I was meaning is if/when you move, clean out the sandbed ideally and move only clean sand, and the current rocks, and it wont recycle
that live rock was skip cycle live rock from the day you put it into your reef, coralline is present. it spent years underwater somewhere else.
its so new, the sand isn't likely dirty but to clean it doesnt redo the cycle anyway, and is a good habit for any moves. i wouldnt use the cracked tank but try and return it agreed, hold your items in a kitchen container of some type. if there is an api test kit or red sea that says you arent cycled, the test is wrong
in 100% of cases, any live rock with coralline and algae is fully cycled and moving it tank to tank doesnt kill it at all. shipping it might, but not moving by car from lfs to home
that will at least save you any degree of wait or expenditure regarding a cycle, you're dealing with old rocks. move it as you please they'll be fine.
those rocks could be taken, sat out on your counter for two hours, put back in the tank, and skip the cycle infinitely.
some real reefs get air for ten hours daily for millennia, they laugh at two hours exposure in nature comparatively
