Hi, and welcome to the forum!! You're going to need some metal sequestrant in the pool to keep the iron in solution in the water. Higher chlorine levels and higher pH levels tend to make the metals precipitate out of the water and show up as brown or orange (iron) or green (copper). By adding the metal sequestrant it should stay in solution and allow you to clear up your pool. You may have some staining, but that can be dealt with later. Read the directions on the bottle, but I believe you're supposed to lower the pH to 7.0-7.2 (don't go below 7.0) and add the sequestrant. It may cause your chlorine to drop, so keep an eye on it.

Hopefully Marie will be by shortly to give you further instructions.
