Some years ago, I used X-tol replenished in a Kodak hard rubber tank. That worked well, but I was doing 12-15 rolls of Tri-X a week. Now I'm down to about 5 a week and don't want to use the hard rubber tanks - they take up too much room. Can I replenish using the working solution in a 1 ltr. bottle or do I have to have a larger amount of working solution? Is replenishment a good idea with this volume of film, or would 1:1 and discard work better? Thanks.
