I've switched to TF-4 exclusively. I don't know of any silver-based film that won't work with it. Chromogenic films, however, require standard color chemistry.(posted 8732 days ago)Fixing times are incredibly fast. I usually clear the film in 30 seconds. I don't use a hardener, and don't seem to need one. Since my whole process (develop-rinse-fix) is now alkalai, the film never seems to soften at all.
I recommend this fixer highly.
