I was wondering what would actually cause the stain when a goose dropping sits on marble dust. I assume this is a biological stain but was wondering if maybe there was some type of metal in the dropping that would stain.

I have a pool filled with a lot of chlorine and acid and was wondering if adding ascorbic acid would help take these stains out at all.

I have the pool pumped down to about 15000 gallons and have added 6 gallons chlorine and 20 gallons acid and have it sitting.

Pool has very bad water condition and thats why I can't do a real acid wash

I know spinach has a high iron content. Possibly seawead or whatever geese eat also has high iron. The stains look like iron
