Hmmm.....

.1 CC isn't a multiple of .2 or .5. Are you trying to convey that it was barely pink so less than .2, or is the decimal point off? Because that can change the recommendations.

If you just drained and refilled, that much copper and iron is not good. Does the fill water analysis show that level?

Follow the FC/CYA Levels. Lower your pH to 7.4.

Barely pink on CC.

Water is well water so it does have some minerals

OK -- have you had staining issues in the past?

Follow what I stated in the post above.

You will most likely need sequestrant. That is something you must add on maintenance schedule.

Anyone recommend a sequestrant?

From the article I linked to:
Sequestrants based on HEDP, phosphonic acid, or phosphonic acid derivatives are the most effective. ProTeam’s Metal Magic and Jack’s Magic The Pink Stuff (regular), The Blue Stuff (fresh plaster), and The Purple Stuff (salt) are some of the top brand sequestrants. There are also other brands with similar active ingredients, some of which are noticeably less expensive.
