Hi All, I recently just got back into developing my own b/w films at home. Strictly 120 only for now. I have read several articles on Kodak Photoflo and water spot removal. I currently am not using this, but that will change shortly. My process is; Develop film as normal Stop Fix Rinse (cold running tap water for about 10mins) The last step above is where I am confused. Do I add my Photoflo (pre mixed from one gallon stock solution) AFTER I do my standard 10min rinse? I have also read that users fill the tank up with the photoflo solution and slosh the film reel around in this for 30 seconds, up to 1 min, then hang film strip to dry as is. I just want to get the information straight as best as possible so I can improve the quality of my negatives. FYI; my water is extremely hard, and spotting is a problem. I do finger squeegy as well as use a rubber squeege but I think that is not helping my situation. Many thanks , and I apologize if this has been addressed before. Cheers!
