@aumfc, let's try to recap a few things:
1 - You're on a well and that water supply has a high iron content. I suspect the builder knew that and "tried" to add a product to control a reaction between iron and chlorine, but that's not fool-proof.
2 - Ideally, you want to remove as much iron as possible to avoid such reactions (hence the polyfill) or replace water with fresh trucked-in water that has no iron.
3 - The higher the iron content, the more potential for iron staining and reaction to chemicals. Pool owners on well water MUST control the FC and pH as much as possible. When the pH and/or FC get too high, it causes a reaction with the iron.
4 - If you try to add a sequestrant product now, you will cause iron to bind with water which will help to prevent additional staining, but will also reduce the effectiveness of filtering with polyfill.
For now, I would encourage you to first focus on completing the pool start-up process. The health of your plaster (with proper testing) is a priority. You can address the staining later. You can review all the info we provide to determine (later) how you wish to address and manage the iron in the water. Polyfill filtering, frequent use of sequestrants, or an Ascorbic Acid treatment later followed by a water exchange are examples. The fall may be an idea time to consider an AA treatment. For now, continue to filter as much iron as you can with the polyfill. The more iron you remove now, hopefully you'll see less staining and reliance on sequestrants. Success stories are out there, much like that example (link) provided above. You can do it.
