Got it it from photographers formulary. (book and chemicals) It is said to be nasty stuff so buy some rubber gloves. There's some very good reason knew once why they wanted you to use this stuff. "Pioneer work on the technique was don by Willi Beutler working for Tetanal-Photowerk in Germany. His formula, originally published in the Leica news, ..." by Gerald Koch in Dignam photographic 150 do-it-yourself Black and White Popular Photographic formulas vol. no 1g 1977 Metal, 1grm, Sodium sulfite, anh., 5g, Potassium Iodide, 0.001% solution, 2.5 mils, Sodium Carbonate, mono 5.85g, water to make 1 liter. I have always been 70 degree guy I developed panatomic x for 9 minutes with a one minute water presoak. I think I used to use photoflo in the presoak. I always you metal tanks and agitate the fist whole minute and for ten seconds per minute alternating between inversion and rotation. Despite recent revelations to the contrary.
