I think the key here is the "freshwater". I wouldn't recommend dipping any stressed coral (or most healthy corals) in freshwater. The CoralRx or iodine dips should be mixed with saltwater if the intent is a therapeutic affect on the coral (e.g., treat an infection). Zoanthids can close up to protect themselves from the freshwater, but most LPS are going to suffer a negative outcome.

Ok. Well thats good to know. What would you do a fw dip for?
CoralRx is amazing I have never encountered a issue with it I use to dip everything just use a air stone or small pump when doing it and only use 4 capfuls per gallon. Then rinse the coral in another tub of saltwater before putting back in the tank.
But for what? I thought a fw dip helped to cleanse it from the iodine dip.
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.
