Be careful with the accordian style 1 gallon jugs that you can buy at photography stores. I picked up two of them a few weeks ago when I was mixing up my first batch of diafine. I extended the jugs all the way, they compress so that when you start running low, you can squeeze out the air, and poored the powder in. I then took my 1 gallon of distilled water and poored it into the jug. 20 seconds later, I had water & diafine chemicals pooring over the side. Apparently the jugs do not hold exactly one gallon. I'm dissappointed, as now i have a batch of solution A & B, but they do not have exactly one gallon of water in them.
I'm finally getting around to souping film tomorrow morning, so I hope all goes well.
