If you have already filtered it and are wondering which is to be used in the developer, the liquid that goes through the filter is discarded and the solid retained by the filter goes into the developer where the additional hydroxide will dissolve it. As I said above, if you have not filtered it, don't bother. Just add the extra hydroxide and sulfite and you're ready to go.

By the way, 1 + 20 makes a paper developer that works in 2 minutes or less on most papers.
