I bought the press kit because I wanted small amounts to start with. Still haven't started, since I read here the chems don't last long I wanted to do all my test rolls at once. I suppose if the blix is not strong enough, these won't be rolls that matter greatly to me anyway.

Can the liquid concentrates be diluted for each roll you develop rather than mixed all beforehand? Or does that not help extend the shelf life at all?

Is there any reason photo-flo can't be used? I assume it should be fine but I don't know.
