Little bumps like that could be Carp Pox, but with inflammation like that there is most likely a parasite involved (if the water quality is not to blame). You should look at a light skin scraping under your microscope (I recall that you have one) and see if there are any skin flukes. If not then it is probably a protozoan, and you should add another 1 lb of salt per 100gallons. You might even want to follow that up with a third addition of salt later.
