Thanks, I've been using the odorless fixers, so my wife won't complain about fixer smell. My 'Hypo' is Kodak hypo powder, and it is with sodium sulfate or sulfite. I assume the odorless fixer is the same. Next round I'll go back to rapid fixer and also buy some air freshener.
I have been successful at not getting the pink negatives, but at one time with Trix I did.
That was a great explanation of fixers, It has been 55 years since my general, organic and physical chemistry days so I'm rusty. You made it simple to understand.
EDIT: I've liked Tmax and TriX because they are less sensitive to blue light, and that makes them more agreeable to California lighting.
