Good luck. I never had a problem with my Unicolor 8x10 tube once I realized that the emulsion goes toward the inside of the tube. I am using an 11x14 unicolor to do 4 5x7 sheets. I have no idea how much solution I am supposed to use. I put 400ML in the tube and got a 1 inch super dense strip on the bottom of all my negs. At least the line showed me the tube was level.

Anyone else use an 11x14 tube?
