It seems like a lot of chemical for six sheets of film. I can do four 4x5 sheets in a Bessler color drum with 200ml of solution. I finally found a motor base for it, but up until now have just been rolling it back an forth on a 2x4 with great results. I also have a Yankee tank that will do 12 sheets (24 if you put them in back to back), but have not used it yet.
