HI birddog, and welcome to the forum!!
Your post is almost identical to literally hundreds of other posts we've gotten over the last few seasons, so don't feel alone! When you fill a pool with water containing metals, and introduce that water to high chlorine/high pH, the metals precipitate out and cause brown water like you have. So... your next step needs to be to log out of the forum, go to the second section of the forum, first topic, called "Pool chemistry for Intex-type pools". Once you open that, the first sticky is called "Before you fill your Intex-type pool with well water". Read through that sticky, because it will give you almost all the information you need to understand what you're dealing with. Once you've read through that, then come back and we can go from there.
You can manage the pool with well water, but it's a little more complicated than managing a metal-free pool. YOu just have to be willing to bite the bullet and do it.
