I picked up mine locally from @uniquecorals so there wasn't really a curing process, but I wanted to see what was on the rock (or in the rock). I have a bunch of colonial tunicates, which are kinda cool, but they spread like crazy. I also had some halimeda grow from mine and now it's growing in my nano system. I used to grow a few different species of halimeda in the 90's, so it's kinda cool to have some again.You guys have to cure it?
