Algae on coral that can't be removed to dip

[Ziggo420]

I have a couple of LPS that have algae on their skeletons, but the rocks they are attached to are too large to remove. What are some options for treating them in the tank? My CUC is keeping the rock clean but won't touch the algae on the corals. Thanks in advance for any advice.

Tweezers or your fingers to remove what you can. The rest time will cure.
