So your asking about how to QT corals that have flatworms? What kind of corals? SPS, LPS, softies?

For SPS I use a dip with Tropic Marin Pro Coral Cure (iodine dip), and then I treat my QT tank residents with interceptor. I try to treat to avoid three things; red bugs, nudibranchs, and monti-eating flatworms.
