Can i use tap water from my faucet for water changes?

if the chlorine, phosphates & copper tests are okay can I use tap water? What level should these be when tested. I have a 45 gallon.

Yes..... my water sucks here in Las Vegas so i cant but if yours tests out then by all means use it, is the cheapest thing you will be able to use in your tank. Try a tds meter or find someone that has one and see what your total disolved is and let us know.
