Okay, so about a week ago, I was doing some darkroom work, and when I finished up, I left the dev, stop, and fix out, intending to go back in the next morning. Well, it never happened. In fact, with "real life" getting in the way, I completely forgot I left it in there. Brown crud in the dev and stop trays... and a tray full of fixer crystals. Obviously, the dev and stop are done-fer, but what about the fixer? Can I redissolve those crystals and use them? It was fresh fixer, far from exhausted. Or, shoudl I just dispose of them and mix fresh?
