Has anyone used aquarium water on their orchids?

I've been watering all my houseplants including orchids for years now and I see no ill effect of any kind.
NYC tap water is fairly soft as long as one lives in a relatively new building. I hear most water issues in NYC gets bad stuff in it via old pipes.

For my fish, I use chemicals. one drop per liter kind of thing that comes in a small plastic bottle.
My fish is happy.
