Hi all this is my first post,
This is my first marine tank so i'm just experimenting at the mo, i bought live rock from my local fish shop the guy there said put the rock in after a week which i did, a week later there is some sort of grass growing on the rock and there is a really bright green blob on the rock. Is this normal?
