Anyone use aquarium water for orchids?

I did when I first started. I then rationalized that it was the de-chlorinator that made it better. Now I just mix de-chlorinator in the water that I have the fertilizer in. Chlorine/chloramine in water is unnatural. My orchid roots have been great since I stopped subjecting them to the chlorine in regular city water.

Why not just let it evaporate? I fill up a few gallons of water and let them open for a few days. Chroline fully evaporates.within a few hours, chloramine takes longer but at 1-2ppm it should be gone after 2 days or so (correct me if I'm wrong!)

You're wrong. Chloramine is stable and doesn't evaporate. It needs to be either chemically neutralized or filtered out.
