It is not Jobo that is the Problem, but Xtol. Each roll of film needs at least 100cc of pure Xtol for rotary tube processing. This is in Jobo's and Kodak's web site. When you start diluting the Xtol, you soon reach the capacity of the tank. I don't know if this is a problem with the normal hand agitating. I have two of the Jobo Automatic processors and in the case of the ATL-1 you can only set the quantity of chemicals for all of the steps at once. In other words, if you want to put a litre of diluted xtol into a tank, it will also pump a litre of stop and fix, when it may only need half of that for the stop and fix. With my ATL 1000, it just pumps out the total volume that you put into the chemical storage bottle. So you could put in 750ml of diluted Xtol and then the smaller quantities of the stop and fix into their respective containers. With the ATL 1000, your chemical bottle storage capacity is only 750ml . With 1:3 and 1:2 dilutions, you can only do about two films in a four or five roll tank. At 1:1 , you can do four rolls. For simplicity sake, the Xtol has tended to go bad while I just used Rodinal. Jim Brick is right about Rodinal. It is simple to use and lasts forever. Works great in the Jobo as well as the quantities of raw developer per roll of film is pretty low. All the talk of Xtol has got me thinking about trying it again.
