Stephen,(posted 9005 days ago)it seems that using the JOBO expert drums don't allow fixer on the back side of the film. I additionally fix my negatives in a tray for five mintues, and the then wash for thirty. I live in the mountains of Oregon, and during the winter the river I take my water from gains a high turbidity. it exceeds what I can filter, so I wash in the trays and watch the purplish tinge gradually diminish with each changing of the water. I used to use a hypo clearing bath, but found that a long rinse works well.
