Using ascorbic acid for stains

[jwgillis]

I plan on using the "AA" process with Jack's Magic Stain Solution 1 and Jack's Magic The Pink Stuff as the sequestrant agent. I have identified the stain in my in ground fiberglass pool as an iron stain.

Question: Has anyone had experience with the products mentioned being used in a fiberglass pool?

Cannot state that I personally have used these products in a fiberglass pool, but I can tell you that Jack's Magic sequestrants are what we recommend. The Pink Stuff (regular) should work best for you as is more aggressive on iron stains vs. The Blue Stuff. Here is more info: Metals in the Water and Metal Stains and Ascorbic Acid Treatment.
