Slightly purple is normal. The magenta/purple tint many complain about is not a fixer problem; it's insufficient removal of sensitizing dyes. To remove it give 3-5 min in film-strength rapid fixer, then two mins in a wash aid such as Perma Wash or Orbit Bath, then a 20-min wash. You can make your own inexpensive wash aid by dissolving a tablespoon of sodium sulfite in a quart of water.(posted 9236 days ago)
