Planarea or some bug on Elegance coral.

[James w Lewis]

I have 3 tiny elegance corals that have been with me for about 3 months. I noticed on 1 that it had small reddish brown spots on it that were at different locations as time passed. If I took my pinky nail and touched one of these spots I could scrape it off. Im assuming they are planarea or some other bug. I dipped the corals in Seachem reef dip but it doesn't seem to have done any good as they are still there and spreading to the other ones. What do I do to get these off?

A picture is worth a thousand words. Esp finding out what the bug is.
There are good bugs too.
I was recently turned on to hydrogen peroxide. 5(w) to 1 (per) 3 to 5 min dip. rinse well.
