    I have just opened a "new" bottle of Idflord Hypam fixer and its cloudy.
    I have had the bottle for a few months and keep the stuff in the Utility Room where the temperature is never too far from the rest of the house.
    I filtered it and it kept the clear liquid.
    It clears film OK
    Have never had this happen before
    Any ideas? :confused:
    Thanks
    Martin

    I've had that happen to an opened and old bottle of the same stuff. It continued to work, but its capacity was diminished. Eventually, even fixers go bad; the sulfur precipitates out and the solution becomes cloudy. You can also smell the sulfur. That "new" bottle of Hypam likely wasn't very new.

    I was using a Rapid fix for some time but it seemed to
    weaken. I'm more off than on in the darkroom and my
    volume of prints is small. So, I switched back to plain
    unadulterated sodium thiosulfate. A quick, easy to
    mix fix at film or print processing time. That dry
    concentrate may never go bad. Dan
