Flatworm Problem

[ramitc3]

So I have a pretty bad flatworm problem (I think), and I am not sure how to get rid of them. I only really see them on my frogspawn, and a few on my leather coral. I heard they could suffocate corals, and deprive them of food that they would normally get. How should I go about removing them? Flatworm Exit?

I used Flatworm Exit but didn't get good results until I had quadrupled the dosage. I have read of other people having to up the dosage as well. No harmful effects to the other inhabitants.

I added a melanurus wrasse and my flatworms are gone. Melanurus are one of the few wrasses that will eat flatworms.

If you still need help, bza was selling a blue velvet nudibranch, which eats flatworms.
