Kodak recommends using at least 100ml of XTOL for each roll of film. If 
your tank needs 250ml of liquid, then use 125ml stock XTOL and 125ml water.

The 100ml/roll rule can be safely ignored up to a point; when I was 
developing in my Jobo, I used the 1+3 dilution for XTOL. In a 500ml tank 
holding 2 rolls of film, this meant 125ml XTOL and 375ml water, so that 
there was only 62.5ml of XTOL per roll. It worked fine.
