I know. I just googled you mentioned. I ended up at Photographer's Formulary. But its service life is so short, I'm not going to buy it. Probably the best thing is to just get a few packages of Kodak Fixer, and use it as a second fixing bath to this free stuff. Thanks for your help on this.
Well I see it's just about dark outside right now, so it's time to set up the trays and get back to my tests.
