Here is an alternate answer on the photo-flo question. After the photo-flo, while the film is hanging, I use a high quality sponge on both sides of the film (simultaneously) with very light pressure. Make sure the sponge has been wet with the photo-flo water and then the liquid wrung out. I have never had a problem with damage to film using this technique, although I do user a fixer with hardener.(posted 8495 days ago)
