adding LR to established aquarium

[herp_mommy]

So I ordered some live rock online for my 75gal saltwater tank. It was cured before being shipped, but it's been in transit for two days. Do I need to cure it again or can I add it directly? Should I do a freshwater dip to get rid of any nasties? If I dip the rock already in the tank to get rid of a xanthid crab, will it kill the bacteria on the rock?

I would highly reccomend curing since transit time was two days.

It just arrived. There's mud coating almost every piece. I assume i need to scrub that all off?

+1, you dont want the rock having die off and starting a new cycle. Cycle separate then add it to the DT.
