John, are you using an acid stop bath after development? Benzotriazole is a pretty effective method of reducing fog. Also use a developer with Paraminophenol. Rodinal is a pretty good developer for low fog. Also a gram of borax to a liter of Rodinal will work pretty well. You can use household borax, but not Boraxo. Some people use a quarter teaspoon of Ascorbate to a liter of Rodinal, and while it helps with grain, I think borax is a more effective method of adding a buffer to the developer.
