Something odd has started to grow in parts of my tank. What is it? I am trying to ID the green algae in this pic, it has many branches and is tough to remove, it's really dug in. Do I need an urchin for this job? Seems to have "roots" or vine like parts that are stuck in the rock surface, impossible to get out by hand. algae looks like a weird tree branch of sorts.
algae ID?
