IDK. I think there probably is one for HQ, as one oxidation product is bright green. I'll give it some thought.

Pardon, all, if I missed a point by reading the first few posts then skipping to the end. But I did notice one thing that was not made explicit early on: and what ye olde lab ratz taught me----take the film, or the prints, out of the water before you dump the water. That way, one is not redepositing some of the fixer back on. That's the way I have always done it, when not using a steady wash stream. Of course, I am fully ready for all the experts to tell me why the old guys who did this were wrong.
