Algae on exposed coral skeleton

[Moogled]

I tried that, but the algae seems to have "hardened" on the skeleton. It's much harder than brushing diatoms off the glass.

did you try joes juice. It takes care of most algae. Perhaps put it in a bucket of still water and apply the "serum" with care as not to get to much on the living coral. I noticed that when I killed aiptasia with the joes juice, it also killed the area of hard algae around it to, while still leaving the Zoo's intact...
might work you never know..

I agree with reef raf try cutting away infected part...

I did some surgery and used tweezers to snap off bits of the skeleton that had algae.

How do I prevent the algae from growing on the coral? I always assumed that algae would grow no matter what and I'll be doing more water changes to lower my nutrients.

All I can think of is continue to have good or decent flow on it, and it should prevent the algae from getting hold. I wish I could provide you some other suggestions.

I agree with Catherine they love lots of flow !

shade the portion of the coral that has skeleton exposed to discourage algae from growing on it.
