Unfortunately, I have to mix all 10L to avoid having to preserve the concentrates and measure all that stuff out each time. I found some hermetic glass mason-style jars locally that are measured in liters, so I'll mix up 5 of those for the developer. The fixer in the Trebla kit is 3 x 5 liter of working solution, and the bleach is one gallon. I don't think I'll need to divide these up any further.
