I’m dipping my feet into processing my first few rolls of slide, I’ve bought the extra bottles for storage, bought the Nova heater for exact temp control, bought the chemicals a few months back and think I’m just about ready. Two questions, I’m gonna use Tetenal E6 and there are six bottles in the box, you are given instruction to mix 4 chemicals so what are the extra two for, Colour developer part 2 and bleach fix part 2, second question is the water used to rinse, I can only heat it up to about 24 to 26 degrees is that ok. :?:
