I just use Kosher salt for my NaCl. Seems fine. If you ever want to do some sort of re-development toning like thiocarbimide, all you'd need it potassium ferricyanide and potassium bromide....the NaOH is available at the hardware store as drain cleaner.....not exactly analytical grade, but it seems to work. I usually order from Bostick and Sullivan or Artcraft Chemical.
