I was reading the Wikipedia article on E-6 and it states for the first developer step: "Originally this step used an acetic acid stop bath, but was replaced with a water-only bath for process economy". When I develop my E-6 at home I do this three times: I put in a 500ml bottle of water at the right temperature, let it agitate on the Uniroller for a minute repeat. I don't have a source of tempered water in my basement to wash with. So with this situation in mind, would it be better for me to use an acetic acid stop bath wash instead of just 3 bottles of water? Would it ensure better washing?
