Hi Wallace;

    I can't really answer your question, but there have been some comments
on the list that it is OK to add synthetic to mineral systems but not vice
versa. Personally, I would stick to whatever the system was designed for. As
for a flushing material, the proper grade of pentosin (ah, the horror, the
cost!) would probably be safest. Hopefully a more knowledgable lister can
give you a definative answer.
    I know you can answer my question, however - what colour is the
synthetic? Some listers have said it is red, some say it is green. You've
seen them both - what colour IS this stuff?
