Algae keeps growing out of acro?

[SamMule]

The coral doesn't seem bothered by it, but I have this stubborn string of what appears to be algae growing out of my acro only in this one spot. I've removed it several times, but it keeps coming back. I even put a glob of super glue over it and it just found its way around it.
Should I just leave it or what?

Frustrating for sure. You'll probably need to keep removing as once it gets too big, it will aggravate the coral

a little shot of H2O2 will take care of it. just us a syringe.
