I wish I can get a pic of this but when i do it doesnt come very clear but anyway Ill try to see if anyone knows maybe what it is.

It looks kind of rust color and on some rocks I dont think its algae but maybe it is also I have like redish hair algae what will cause that and howe you get rid of it.

After looking it up I beleive I have this:

Lobophora variegata, Encrusting Fan-Leaf Algae. Fan-shaped blades that encrust rock. Occur in brown, red, green colors

first, how old is the tank? if its new its likely just a diatom bloom. However i dont know if its common in a tank 2 years old...check all your nitrates and phosphates. Those both feed algae.
