I don't want to hijack but wanted to point out that the coraline is no indication that the rock is 'live'. I'd suspect dry rocks takes at least a year before being as good as true live rock but I'm only guessing.
My pvc return elbows have coraline on them 1 month in but they're certainly not live...
It's too bad you can't get the BRS dry fiji anymore. I thought mine looked a lot nicer than the other stuff available to us now.
