Timeline for mixing Live Rock and Dry Rock

[DiscGolfRob]

My tank is just about ready to get wet, so it's time to commit to a decision on live/dry/mix rock. For a 50G cube (68G, with sump), I currently have 30lbs of dry rock. I would like to supplement with 10-15lbs of live rock, most likely from KP Aquatics or TB Saltwater. The reason for this is not to speed up the cycle. I've had the tank since February, have been extremely measured in every step of the process, and will continue that way. Rather, my reasoning is biodiversity. I wanted a reef tank because I love ocean life, so I'm willing to risk pests to have as much ocean life as possible.
Should I add all dry and live rock, at the same time? This makes the most sense to me, as it is all technically uncured. Or should I get the dry rock going, and then add the live rock?
I'm also open to other suggestions for biodiversity. Indo Pacific has some pretty neat looking stuff, but I believe that should all come, post-cycle. Thanks!

If the goal is to preserve as much biodiversity on the live rock as possible, I would cycle the tank with dry rock and then add the live rock.

With live rock there will be die off. Most people just cure the rock during this stage but much of the more sensitive organisms will die during the same period. If you add a small amount of live rock to a cycled tank, the die off will much more minimal and you can preserve the max amount of bio diversity.

The old school way would be to cure the live rock in a vat until you are not reading any nutrients any more. Much of the life will survive and you can do it this way as well.

That makes sense. Thank you so much for taking the time to answer and explain!
