For now, however, I am using Xtol and Tmax (TMX and TMY) exclusively, hoping to learn them really well before introducing more variables. Rodinal oxidizes quickly; Xtol stores very well. In either case, I only mix the working solution immediately before use. I store chemicals in 1 gallon "Air Evac" plastic bottles, aside from the Xtol, which needs a 5 liter container. Unfortunately, the one supplied by Jobo has no special provisions for squeezing out air, but then, Xtol doesn't seem terribly fussy in this regard. I've also recently discovered collapseable Nalgene bottles in 48- and 96-ounce sizes. As needed, these larger containers are used to replenish the 600 ml containers provided with my Jobo processor. Chemicals from these small bottles may be reused, but are never returned to the larger containers. In a pinch, 1- and 2-liter soda bottles work well too. With your 2-reel, 470 ml tank, you can use Xtol either full strength or in a 1:1 dilution.
