I am having the same problem with my pool. I have some brown stains, but they are only in the middle of the pool and a little around the steps. My pool man says I need to have it re-plastered for around $3500. I don't think he knows what is wrong with it so I'm anxious to find it if anyone has an answer for your questions. My pool is 35' x 15' and 6 feet at the deepest.
I just called my poolman and asked if he had tested for metals. He said he didn't, but will next week. I may beat him to it. Then I can be the poolman.
