I just bought a Fuji Press Kit, it uses the Bleach and Fix in seperate baths, so I should add the stop bath then just *after* the first developer? I once used normal tapwater as a stopbath, but that didn't resolve this problem. Could I use a stopbath I use for b/w development for this?

btw, I found this document some time ago, that is the reason I gave the 'alternative' way a go.
