25ml of hypo (same as for when printing the kallitypes)
1 litre water

5-10 minutes in this is usually sufficient.
Are you using this technique with toned or untoned prints?

I tone all of my prints with palladium or platinum and and this procedure would not be very effective since most of the silver has been replaced or coated with palladium or platinum, which won't bleach.
