MEANT SODUIUM CITRATE pH question
DEAR DON, I sit corrected. I DO use Sodium Citrate, NOT Potassium Citrate. Senior moment! I was thinking Potassium Oxalate when I was typing Sodium Citrate. Sorry! ******So, do others agree that pH 6 to 7 are good for SODIUM citrate PT/PD Dev? CHEERS!

For that I adjust pH < 7 and > 6 with citric acid.

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!
