My 10 gallon tank has about 10lbs of live rock that has gotten covered in brown algae over the last several days. I did have purple and light brown and it is either disappearing or being completely covered. I have put several snails in to help, a emerald crab, and some hermits. If I scrub some of the live rock will I being scrubbing of what makes it "live". Also the light is basically only off at night. So I have turned that off as well during the day. Any thoughts, suggestions. I don't want to damage the bacteria on the live rock.

How old is the tank? Could be diatoms which are normal and will dissappear almost as fast as it showed up.

is the brown stuff almost like rust? does it easily come off? If so, probably diatoms

Ah ha, I'm glad I read this thread. Answers my brown/rust live rock problem. I didn't try to rub it off but I did touch it to see if it was slimy but it wasn't.
