hi, I bought some Tettenal Superfix Plus (concentrate) and the label is mainly in german. It says for film - 1+3 - 1+9 Does that mean either ratio of concentrate to water is fine? It also says 20 degrees Celcius: 2-4 min. I assume that means you fix for 2-4 min at 20 degrees? It also says capacity: 6-18 films. Again, I assume this means that the bottle of conentrate works for about 6-18 films before becoming exhausted? I also bought some Kodak Hypo Clearing Agent and Photo-Flo. Do i need both and when do I use the hypo clearing agent? Is it best to mix up the whole packet of powder or only what is needed? (It says stock solution last about 3 month) Can i re-use hypo c.a, if so what sort of life expectancy? Sorry for so many questions. Thanks heaps.
