Response to Ilford Delta question

I recomend a two bath fixing routine. The first fix bath wears out first. Then you toss it and use the second bath in place of the first and mix fresh fixer for the second bath. Theses are stored in two bottles, of course. Determine the clearing time in new fixer wit ha piece of leader. Put the film in each for 1 1/2 times this period. Visually inspect the film after the first bath. When the film takes twice the original time to clear the first bath is exhausted. Replace both baths after four swaps. Fixer capacity is greatly extended this way.
