Mix chemicals in the listed order. Make sure each chemical is completely dissolved before mixing the next one. Use distilled or deionized water for improved keeping properties. The stock solution may be diluted with tap water at the time of development.

FX-15 (especially) and FX-18 are probably better developers.
