Hello, I couldn't find a thread concerning about this subject in this forum. I hope I am not mistaken and my questions are relevant. I developed my first roll of film 21 days ago and I want to develop 2 more rolls right now. But I am not sure if I can use my stop and my fixing solutions after all this time. I used Ilfostop and Ilford Rapid Fixer in my first try and stored them in dark glass bottles in case I would use them again. A friend of mine told me that I can use those solutions for 15 times at most before dumping them for recycling. Is that correct? Or should I make another fix and stop solutions because of the time passed. What is your method of storing reusable film developing solutions?
