Clean up algue on skeleton??

[vincent3oo]

Hi eveyone

I had a high no3 issue last month. Now it is controlled at 25. But now i found some LPS has attached algue on their skeletion. So that the tissue cant cover it back. I tried to use sharp thing to scratch lightly. It seems doesnt work.
Anyone have solution?

I have some stronger hydrogen peroxide and a water dropper and I drop just a little bit of hydrogen peroxide on areas that I want to clean up and it does the trick for me p

I would just let it be. If you fixed the nitrate issue, the coral will recover. Also, use small snails for cleaning hard areas like these.
