Aptasia in my overflow

ok, wondering if i should actually worry about aptasia in my overflow. I have a "C" overflow and the aptasia are in the enclosed area of it out of reach. it started with one, and now i have about six. I have no aptasia in my DT or my sump, but I just don't want them to become a problem.



Removing the overflow is a long and painful process...would like to avoid it...



Any suggestions?
