ID Orange Algea Please

I have no idea what this orange algea is and if it is harmful, and if it is how to get rid of it...any help would be greatly appreciated.

Sorry here is 1 of the photos of the orange algea I am asking about...there are three other photos in my gallery...

Tom and Sharon:eek:
 
I dont see any orange and went to your gallery. I did see a hint of orange on the underside of a rock that I would guess is actually an encrusting sponge. They would be good for your tank so dont get rid of them. I have them in my tank and tend to be slow growers and only attractive when I am able to look up at them......
 
You mean that dark brownish-orange, encrusting growth?

Probably Lobophora variegata.
Do a search for it on RC... you'll find a ton of suggestions, some good and quite a bit very bad.
