its in 28g jbj nano cube 150w MH and 2x18w PC actinic. 15% water change weekly.
 
If no predators in the system, I would say it is a bacterial infection.
If bacterial infection:
Remove colony from the system and cut off with a sharp razor blade and dispose the infected zoas first.
Treat the rest of the colony with Lugol's solution:
-> 3 to 5 drops per 8 to 10oz of tank water for 1 or 2 minutes, and see what happens.

Good luck!

Grandis.
