The problem occurs with both TMX and TMY 120, developed in D:76 1:1. Times are 7-11 minutes, and happens with three different tanks and assorted (9) reels. This, unfortunately, is plus density, not a light leak, and something Jobo is aware of. Right now, they do not have a solution, although we are trying a few things.(posted 8787 days ago)I was looking for anyone else who has had this problem to see how they might have solved it.
