As best I can tell based on comments from others and web research, my purple acropora lokani is infected with ostreobium green boring algae. Apparently, this algae can cause problems in high nitrate environments, which was a problem with my tank until only very recently when carbon dosing got the nitrate levels down.
It appears to be infecting two other frags in the tank as well, both acropora. It's in the very early stages on my ice fire echinata and has made significant progress on another smooth skin acro.
My nitrates are now about 1-2 ppm, with phosphate at 0.16 ppm, which I believe is pretty close to well-controlled values.
One article suggests the use of controls for the cyanobacterium that cause Red Slime Algae and Black Band Disease, as the suspected cause of Green Boring Algae is a similar cyanobacterium. These are products like Ultralife Red Slime Remover.

Does anyone have experience with this disease and how to control it?
For reference, my water parameters are:
SG: 1.025
Alk: 9.0
Mag: 1320
Ca: 435
Temp: 79
