White bugs on corals

[jimskoi]

I have these white bugs that are in some kind of a slime on my corals.I have lost brains,mushrooms etc to these guys.Does anyone know what they are and how to get rid of them?
No they are not pods.They are the size of a pin and move around in the slime that rests on the corals.They turn the shrooms to brown slime and the brains tend to string out and then die.
Any help would be great.
BTW.The water is great.Its not affecting fish.

I tried but they are really small.The size of the end of a pencil.They are also on the substrate.
It dosent bother my clams or leathers.Even my frog spawn is fine.
