I have some red spots on the viewing side of my tank.. I use my alage brush to remove them and a couple days later they are back. What kinda of alage do you think this is? What should i do to remove it?

Could it be coraline? It take some extra elbow grease to remove it.

if its hard and crusty, its coralline. If soft, then its something else.
