I've been happily using the Hunt 5L kit for a while now, mixing it up in 300ml batches as I go along. Recently, however, when I have mixed a new batch, the component C of the Dev (which I assume to be the CD-4), has produced a sticky tar-like gunk precipitate, most of which floats to the top and can be whisked off, but I have found it impossible to remove from my measuring beakers.

Despite the apparent loss of something from my dev, and the cloudy aspect of that which remains, this issue does not appear to be having an adverse effect on my negs. Anyone else seen this problem before?
