Hi Cory! Was approached by another moderator concerned about high levels of Mg salts could cause problems for frog. I know aquatic frogs are fine with it (i.e. ADFs) during fish treatments in tanks and appeared to help one local sick Pacman (not mine) that eventually did get better. Just letting you know there is a risk involved even if Epsom Salts help with edema. I would stop doing soaks if frog looks increasingly stressed during soak or as soon as edema goes down. If no effect on your Pacman after a couple days; might as well stop it too.
