Judith Hauptman Mikveh is not practiced during the day but at night, for women after menstruation. For converts in the daytime. Nighttime is for modesty for women and also, the first available moment for immersion is after sundown, since a new day or date starts. Women are urged to go right away. That's interesting, I thought there was something mentioned on the discussion list about it only being done during the day Shari Rob, women go to the mikveh at night.
Men go during the day.
Men are presumed to be emotionally volatile. What I meant by water showing innocence is that the sotah's potion, if she is innocent, has no adverse effect on her. This shows her husband that she is innocent, not guilty as suspected. This seems to be the point of the entire water rite in Numbers, to allow a jealous husband, with no evidence, to establish his wife's innocence and resume a marital relationship. Bonnie Judith, While I am not a mikvah scholar, I might have answered that differently.
