I had a pretty bad infestation of Dinos. Don't know the strain as I didn't had the means to identify them.
The only approach it worked for me was to raise PO4 to 0.25 and NO3 to 10 maintaining it there for about 3 weeks.
All the corals browned out a little but soon bounced back.
NOTE: please keep an eye on Iodine. With the proper levels I noticed that the corals handle the dinos and PO4 raise much better.
