Maybe I'm a blonde in disguise because I have some of that Edwal fixer check right next to my fixer bottle...lol. I havn't used it in so long that I totally forgot about it, and the label is turned out of view. In any case I had already went ahead and used this batch of fixer for the set of prints I just made. If its not yellow and they fix test comes out negative I may be able to use it again for some test prints.
