confusing coralline

If this is a new setup, could it be that the "dieing off rock" was dried out at some point before you received the LR? So after you put it into the aquarium, it was already dead?I know it bleaches out in the sun without water.
Hopefully it will grow back after a month.

nah, it came out of the tank up at the shop and went right into a bucket i had brought with me (bucket topped off with their water). took it home, acclimated it to our water over a couple days and threw it in the tank.

its almost as though one week its taking right off and then the next its dying back on some rocks. some patches recover, others go bare. weird.

There are a few live "things" that ear coraline algae, like urchins and limpets. Probablly others as well
