OK, so I just tried to develop some film and gave up because of the confusion. I have a Paterson 2 reel universal tank...how much am I suppose to fill it up? Is 500ml enough?

On Kodak's site it says "PREPARING WORKING SOLUTIONS FROM CONCENTRATE*", what's the difference between "solution" and "concentrate"?

I'll be using distilled water for a stop bath. Do I just pour it in and agitate for about 45 seconds, pour it out, and do it one more time?

I don't have a damn clue how to mix Kodafix solution.

EDIT:I'm using dilution B
