Sorry missed that question. Once I mix all the chemicals for the entire 5L kit, I separate them into 4x 1L light-tight air-tight wine bags, and 2x 0.5L wine bags.
My regime is like this for the 1L working solution:
- Use Paterson 1L tank (3x 135 or 2x 120 rolls)
- Use full 1L chemical
- Time compensation for color developer (in minutes): 3:15 for rolls 1-4, 3:30 for 5-8, 3:45 for 9-12, 4:00 for 13-16
- I did not bother to compensate for bleach and fixer
- Pour 1L chemical back to the wine bag, squeeze out air and foam, cap
And repeat the above for next few rolls. As I said I use up 5L over about 11 months, so use up 1L every 2 months or so.
