You need to be very careful using bleach with developing 
chemistry.  Household bleach combined with RA4 chemistry, for example, can 
create toxic and deadly fumes.  It has been a number of years since I 
worked in a lab using RA4, so I don't remember which chemicals don't mix, 
but I do remember it was a firing offense to have chlorine bleach in the lab.
