For future readers of this thread:
After bringing up FC to five and watching the pool turn into green kool-aid, I put polyfil in the skimmer and just maintained the FC as if nothing was amiss. After a couple days the water was clear but the stains on the fiberglass were horrendous. I let FC drop down some and did the Ascorbic Acid treatment. I went to walmart and bought 5 bottles of vitamin C. With the pump on recirculate, one bottle at a time I crushed up the pills with a mortar and pestle and poured in along the sides. The stains lifted away like magic. The next day I added sequestrant and the few remaining stains disappeared. FC was at 0 at this point for almost a day so I slowly raised it back up using liquid chlorine. Once it held the minimum FC needed, I turned on my SWG.
The pool looks wonderful now, and I have a reminder to put in more sequestrant every month.
Big thanks to those that responded! @YippeeSkippy @Texas Splash @duraleigh I appreciate y'all!!
