FIXING TIMES
For best results it is recommended that all process solutions are kept at the same temperature or at least within 5ºC (9ºF) of the developer temperature.
General purpose film 1+4 from 2 to 5 minutes
CAPACITY WITHOUT REPLENISHMENT
General purpose film 1+4 Capacity/litre of working strength fixer = 24x135–36
In pratica con un litro di diluizione 1+4 si puo' fare il fix di 24 rullini.
Io con mezzo litro posso tranquillamente arrivare a 6 pellicole senza allungare i tempi di fissaggio...
