Live Rock Questions

[Myka]

You don't have to cook all uncured live rock, but I would strongly reccommend it. A lot of the "really pretty" stuff on the uncured rocks will eventually die off. Mature, cured rock that has been in someone's tank for awhile will simply be covered in purple and/or red coralline algae. Some people get kinda of a reddish brown fuzzy turf algae covering some or all of their rocks too which I prefer, but the coralline is preferred by most people.
