How to Kill Purple Clove Polyps DIE! DIE! DIE! :)

I've been having the same battle. I coat them with a thick kalk paste and it kills them. They spread too fast and I think the only way to rid them is to coat all of them at the same time. But that would be detrimental to your tank. My SPS does grow over them though. What really sucks is the ones I have are brown. Good luck!
