A sun coral (Tubastraea sp.) is non photosynthetic so for the short term the best suggestion is place it somewhere under a rock overhang/cave where it gets no light but still gets good water flow. That will allow the algae to die off without the need to clean the coral manually. If not, gentley using a new soft bristled toothbrush to remove any algae away from the polyps can be done if your very careful. The dark would be much easier on the coral though, just be sure it's placed in an area where you can still easily feed it without disrupting the entire tank.
You will still need to eliminate what's causing the algae growth so post the parameters as Nikki suggested. You don't want such a beautiful coral hiding in the dark all the time.
