Looks like hair algae covered in detritus?

Oooh, the "brown stuff"? Maybe diatoms? I would take a turkey baster to the rocks. Should go away after that?

There are reddish parts in the brown patches. I think it´s cyanobacteria with diatoms, a frequent combination. The cyanos (genus Oscillatoria) make the patchy structure and where they are thicker they dominate with their carmine color. Diatoms are frequently found together with cyanos and make the brown color.
