    With 200 g/l Sodium Thiosulfate Pentahydrate, 50 g/l Ammonium Chloride, 10 g/l Sodium Sulfite Anhydrous and 2.2 g/l Sodium Metabisulfite you get a non-hardening fixer, which works a lot better (as in 2-3 times as fast) than plain Hypo, lasts quite long between printing sessions, and which is fairly easy to wash out (pH about 6.5). There are better/faster fixer recipes out there, but not for this cost of material.

    Thanks, 240 grams/liter if used alone.

    The rest is also great information that I will save and use.
