For fix I mix 600ml at 1/4 and that is good for 10 rolls of either 120 or 35mm film, pour back into bottle every time and after 10 films discard and mix fresh, plain water stop is fine, but use 3 changes of water, invert tank 15 times, discard, repeat 3 times, you do not need hypo clear after fixing, you only need HC with fibre base paper, for wash either 20 to 30 minutes under water or use the Ilford system, fill tank with water at 20, invert 5 times, discard, fill and invert 10 times then fill and invert 20 times, and I like to fill and invert 40 times, fill with photo flo solution and leave 30 seconds, shake film and hang to dry
