I've been developing with a Jobo 2551 on a rotary base successfully for a while, and just ran into a bad batch. Here are the details:
1000ml Pyrocat-MC 1:1:100 for 8 minutes at 70F, T-Max 400. This is the first time I've developed T-Max 400. Mostly have been doing Efke 25 and 100, as well as Arista EDU 400, all successful (and those are what I mainly took on the trip). Since these 8 photos, I've used the same developer for 8 Efke 100 4x5's (800 ml) on the jobo and for a roll of 120 Acros 100 with hand agitation, so I know the developer is ok.
I'm wondering if 1000ml is too much for the jobo 2551. I had boosted to at least 800 due to fatigue of the pyrocat-mc at lower volumes with 8 negatives in the tank. Perhaps 800 gives a better flow?
What do you think? Here's one example, followed by the link to the other 7 below.
