Algae growing on skeleton

Hi,

pics should show what I mean.

NO3-5ppm
PO4- 0.1ppm

I bought the coral with this on it, didn’t think it was a big deal but reading it could be bad for the coral? Any thoughts?

Is it red?
Most algae requires light to grow. The coral should shade it out if it just on its stock.

it’s green, hasn’t spread at all.
