I've heard a ton about what water is safe but l've also head people are using tap water in certain cities so I thought I'd throw out all my questions about the easiest watering options I have available to me to see which ones are safe and what I should be investing my time in. Would fish tank water work with or without fish like can I use fish to prevent mosquitoes from breeding in a rain water container or use old fish tank water that would likely have fish poop in it) I am also already treating tons of city water to get rid of chlorine, chloramine and hard minerals but I think it still leaves some minerals in if it is not safe should I be worried about how I am storing rainwater (like if the container has metal components or is running off my roof that could pick up nutrients from decommissioning leaves) and for my last question would water from air conditioner dehumidifiers work or do I need to be concerned about what it may have come into contact in the attic (insulation, rusting metal, etc.)
