George ; I've pretty much given up on the 2-bath version of DiXactol, as I found it quite unpredictable and difficult to control - the risks just outweigh the potential benefits. The single bath version seems to work better and to be more consistent. Perhaps you could run a test roll of Tri-X through a single bath to see if the problem remains. Final thought ; what EI did you use for the Tri-X - DiXactol does seem to give a speed quite close to the published EI.(posted 8370 days ago)
