Is it really necessary to place live rock in a curing tank for long durations of time?
If you don’t have any other life forms in your tank you can by all means use your tank. If you have only a few creatures or fish you may want to temporarily relocate them. Definitely do not try and cycle with other livestock as the ammonia readings will skyrocket and the best thing to do is just let it happen, and it will happen. It would be difficult to supply a separate tank with filtering equipment to cure my rock. You don’t really need filtering equipment to cycle the rock, it can be done in a clean new garbage can or a clean garbage can with several liners and a few decent air stones. Personally I prefer to use the tank W/O livestock. I have added my live rock that was supposed to be cured…
