Bob,
I don't use Potassium Citrate but I use Sodium Citrate for kallitype
printing. For that I adjust pH < 7 and > 6 with citric acid.

DEAR LIST,
At what pH should I keep my Potassium Citrate developer for pt/pd?
Eric Neilson suggested that I keep my Pot Ox dev at between 5 and
5.5 with small additions of oxalic acid when necessary. I can add small
amounts of citric acid to my Pot Cit dev but I am hoping to know what the
best aim pH is for best development.
Thanks in advance...
CHEERS!
BOB
