First official season for the tiny IG fiberglass pool installed last summer. Now that everything is clean and numbers look good water has a green tint and the sides are slightly stained under the winter water line. I also have small "rust" stains in many areas. I now remember these issues did come up at the end of last season but I didn't take care of THEM then.
After reading many (too many?) posts, I think I have metal in my water and I should add a sequestrant agent. Would this clear the greenish water? I think I should only try to fix one issue at the time, makes sense?
Thanks for your help
