    You're not alone Big...

    Numerous people have expressed concern over the buildup of "gunk" inside of these systems. My good friend Richard "Der Heatmesiter" Graves has gotten to the point, that if he comes across it in the field, he pretty much condemns it. He's tried every chemical in the Rhomar line to no avail.



    I have my theories as to how it is that oxygen is getting into the system, but they are unproven. And you are correct, the manufacturer does not recognize any problems with the tube.



    Sad but true.
