I have some very old film, some exposed, some unexposed. I usually develop in Pyrocat-HD. I’m wondering if anyone has experience with adding benzotriazole to Pyrocat to reduce fog? With most developers, the benzo increases development time, which is not a problem for me.

As Jay recommends, I would just play that game with HC-110, which is directly low fog, and the most popular solution for aged film.

Yeah, I don’t have HC-110. Maybe I should just mix some D-23 and develop by inspection.

Rodinal is a low fog developer that with the addition of the right amount of benzo should do what you want. I've only used this combo on some Fomapan 100 that was only slightly fogged.
