just a couple of questions

just got a couple of questions

after reading many post on here how AI is good lfs to go to so i headed down there and ended up buying 9lbs of live rock. I have to say it was alot better experience than big als and alot closer. when i asked the fellow about the lr he said it was already cured, how much die off can i expect and is it normal for it to be covered in feather dusters?
from what i was told its fiji lr what kind of hitch hikers can I expect to pop up in the future? also its has this purple stuff on it that looks like felt, is that some sort of algae?

thanks for your time
