I'm going to be looking for one myself. I bought 5 Ghost Shrimp last week and need to get something with iodine. I'm considering this for the shrimp. I've used Kent products in the past and they seem to work well. And according to this site, small concentrations of iodine are usually beneficial as well. So pretty much just don't over use the stuff (;like anything else you add to an aquarium) and nothing bad will happen.
