I would like to add some old dead "live"rock that has been boiled and wrapped in newspaper for some time. It is just a couple pieces of old Tonga, less than a pound, that will just fit into my existing rockwork. My reef has been up and running for almost a year and doing great. a LFS here locally said to just put it in and in a couple of months it would become live rock again. Are there any pros, cons, or how to's I should know? Thank you in advance for your help.
