read the post more carefully--you're bleaching TOO MUCH. Do a test to find the minimum bleach time which should be like 3 minutes or so--you're doing 8--it may not be doing any harm, but why leave it in chemicals way longer than necessary? Also clearing--2 minutes max---sulfite is a silver solvant, so you're losing meat there too.
Try a strongerdilution--no dilution. Or move on to a stronger developer--or goose it a bit to make it stronger.
