Dinos or Cyano on my macro?

[FoolintheRain]

Got some feedback saying that this could possibly be cyano or dinoflagellates attached to my grape caulerpa. This has all already been removed and disposed of since the photos were taken, but any feedback would be appreciated. Others said it could be that I just melted it with too much light.

I had dinos on my grape caulerpa. In my case they were ostreopsis. I have attached a picture. Of course you may have something different.
