Are you not recycling any of the chemicals back into the main storage tank? The tetenal 1L kit is suitable for recycling of chems up to a certain point. That's of course how the 1L kit is able to do 12-16 135 rolls. If I were you I'd really look at reusing the chems after dumping back into the tank for atleast twice the sheets you're doing now.
