Now it makes me think I should keep the Ilfochrome tubes and try developing film in them as well. This is a dandy one shot quick check tank. There is a huge difference between 40ml in this and 850ml for taco method in my big plastic tank, and 1.5l in the FR tank. I still like my Jobo for more than one or two negatives though. This certainly appeals to the cheapskate in me.
