But the second developer bath had a low pH and that didn't help CD-4 to work well. I also added sodium metabisulfite to CD-4 to preserve it from oxidation. And metabisulfite makes solutions more acid, so maybe I had less than 9,5 at the end and that caused the development not to be satisfactory. About the temperature, the experience I already made, showed me that all temperature above 26 ºC until 40 ºC will work with no significant changes in results.
