And Stone, I have a request.
Please do not refer to Hypo Clearing Agent as "Hypo". "Hypo" is an old name for fixer. "Hypo Clearing Agent" is still the name for what should be referred to as "Fixer Clearing Agent" or Wash Aid. If you call something "Hypo", all of us "older" photographers are likely to become confused, and think you are talking about fixer.
