For film, use 4 oz of solution A (fixer) and maybe 13 ml of solution B (hardener) diluted to 16 oz as your ratios. Leave out solution B if no hardening is desired. For paper, use 2 oz of A and 6.5 oz of B in 16 oz. I don't recall exactly the amount of hardener to use for film, but the hardener bottle may say. Also, the Kodak web site probably has all this info.(posted 8681 days ago)
