The FW dip is meant to remove pests...zoanthids seem to get more than their share...Nudis, spiders, etc. Iodine would be to treat any infection...but is also a toxin in high concentrations to inverts. However, I think in a FW dip the main active ingredient is the fresh water itself.

I have also used a melafix/saltwater dip to treat LPS that appear to have an infection or other process.

Personally, I would never recommend putting anything other than a zoo/paly in freshwater.
