I haven't tried this before and I was wondering if someone has. I have a Jobo CPP-2 with the Lift and I am happy developing 8 rolls of 120 at once with a 2561 tank. Because of a tight deadline and a mountain of rolls that need to be developed in a hurry, I decided to combine a 2560 tank to make a looooong 16 roll monster tube. Now, considering one tank needs around 1000ml of liquid (less but I prefer to round it up) and that, if I am not mistaken, the instructions warn not to exceed 1500ml, will I damage the motor if I make two-three runs of this volume? I know that the Lift would need assistance to perform its duty but I mostly worry about the motor. I wonder why Jobo has made this combination of tanks available if it is not recommended?
