Has anyone ever dealt with acoel flatworms. I recently look in my sump tank and have spotted a few. I read on the the internet that there really isn't a way to get rid of them, that they will parish on there own in a few months. But they can destroy soft corals.

i'm not sure about acoel flatworms specifically but six-line wrasses will eat just about any kind of worm. Something called a blue velvet nudibranch also eats flatworms but they are expensive and odds are won't live much longer than the flatworms. that may be a help but like you've found flatworms are a difficult one. the only surefire treatment for things like that is copper and obviously copper would do much more harm than good in this situation.

I mean they are only in the sump as I have noticed so far, there no way for them to get sucked to the main tank(I Hope)
