Flat worms?

[mx51]

I think something I bought yesterday introduced flat worms to my tank. I got an anemone, a brain and a sea hare to eat my algae. I dipped the 2 corals in coral rx so the only thing it really could have been was the sea hare.
How hard are flat worms to get rid of and what's the best way to do it?
Thank you for any help...

Siphoning them out one by one seems to be the best bet IMO. Using chemicals in the tank would be a distant second. Check this out.
