I don't know of chloramine and bees, but chloramine and chlorine are also toxic to aquarium fish. There are various "chlorine removers" available for fish at pet supply shops to remove chlorine/chloramine from tap water. The solution may be as simple as using this for the bees, unless it is also toxic to them. I believe the active ingredient in chlorine removers is sodium thiosulfate. -Mike
