Angry corals

[GillianB]

I have several corals in my aquarium most of them have been doing well accept for the Pulsing Xenia, monti, and candy cane. The Xenia and the candy cane have algae on the base that I can’t get off and I think the monti is slowly losing color
Any advice on how I can fix this?
Thanks in advance
