Do I get rid of the rock

[Amstar]

This is the oldest rock in my tank. I’ve constantly fought this algae just in this rock. It’s not anywhere else in the tank. Issue I have is it has some corals on it and one anemone. I’ve scrubbed it before with a tooth brush - manually removed and it looks decent for awhile but then comes back-

Chuck the rock or keep fighting the good fight with it ?

If you like the look the rock gives try and keep it and if you don't really care remove it
