We did some testing and a demo a couple months ago at a meeting. I use bayer, revive, and reef dip (iodine). Bayer is great, but did nothing to flat worms we were testing with, Revive melted them in minutes. Bayer seems to do best with exoskeleton pests, where Revive melts the softies away. I finish up with Reef Dip, as a disinfectant.
