I recently started my first SW
tank. Most of my live rock is dead coral that I found at my favorite LFS
throughout the live rock tanks.
I bought a piece this past weekend because of its purple coloring, not noticing all the algae / lifeforms growing on it.
One is definitely green bubble algae (first pic), but I have no clue what the second pic shows. Looks like crusty cinnamon or brown sugar.
I read to try & vacuum out the bubble algae without popping it, but what is / how do i remove the crusty stuff? any crustations i should buy for either?
All help is appreciated!!!!!
(ps - added a pic of the whole tank too, just for critiques)
