I have a further question: Usually the stop bath turns a bit pink, and with a ferricyanide bleach, to ensure no carryover of developing agent to the bleach, I use a sulfite clearing bath and/or additional rinses between the stop bath and the bleach. Need I do this with the C41RA bleach? I'm thinking of turning my photography into a business, in which case environmental rules will require me to capture my wastes for later disposal - and I want to cut down on waste volumes.
