Response to developer formula wanted

Ed Weston's Amidol Deveoloper is as follows: 1140ml water, 37.5 grams of Sodium sulfite, 10.5 grams of Amidol, 7ml of 10% Potassium bromide and an optional ingredient of 60ml of 10% Benzotriazole. PMK is a film developer and not a paper developer so I don't know if you need the formula for that.
