Developer should be used 1 shot. Fix can be re-used but its inexpensive.
Bleach can and should be re-used. You should test for retained silver. Bleaching
time and fixing time are not too critical so there is room. As bleach is used
the time needed to sufficiently bleach increases. Best solution is to mix
some fresh bleach into the mix (so-called overflow regeneration) and re-use.
This is around 30ml or so per 35mm or 120 film--- check the rate for your
bleach.
