<p>This is what works for me, in a similar situation as yours: <br /> Between developer and fixer, do three rinses (first 10 inversions, second and third 40 inversions) with water.<br /> You are using TMX and powder fixer, so you will have to fix twice. 10 minutes each, and a two-minute wash in between the two fixes. Tabular grain films are harder to fix than traditional grain types.<br /> Keep two small bottles of fixer, A and B (small = enough for your tank size). Use the A first, wash, then the B. Return fixer to each bottle. After four rolls, throw away A. Bottle B becomes A, and you need a fresh B solution.</p>
