David,A pinch of the Metol will also absorb much of the oxygen. One can eliminate most of the dissolved gasses in the water by boiling it. This also removes some of the permanent hardness and will coagulate any organic material in it. Boiling will not remove some materials but a trip through an activated charcoal filter, like a Brita filter, will take out much of what boiling leaves behind. Boil for perhaps 3 to 5 minutes and allow to cool without being disturbed, the syphon off the clear water.
Kodak, in their early chemical books, suggested dissolving some of the ingredients for developers separately and then adding the solutions together. The only drawback is that some ingredients dissolve with difficulty if the pH isn't right. However, this might be a way of avoiding having the Metol come out of solution later.
