Hi! Great Question! Now i don't recommend any live rock because you will t some point get pests from live rock (aptasia, flat worms, bristle worms ect.) I would buy dry rock if anything.. And its good practice to always dip your corals no matter where they come from.. First thing you need is a coral dip like Coral RX, or Revive or simply just some iodine... Then you need a container for dipping just a plastic supper wear or anything like that will work.. just put your coral and water in the container then add the dip as recommended, i recommend getting a turkey baster and gently blowing water all around the coral that your dipping to get any hitch hikers off... Then after about 10 min put them in quarantine or your main display the whole process takes about 10-15 minutes
