pH question

	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...
