I only just finished toning some agfa multi in it and at the recommended dilution.
48 sec a subtle shift in the shadows.
1.40 mins in is a very nice warm shift.
pass 5 and you'll soon see a muddy orange colour.
I also tried (on a reject print) putting into a fix after but that only wrecked the old fixer. The rust that my drying rack left on it was also affected and went greenish.
