WE have an over abundance of phosphate in our pool water. We used recommended chemicals and it the water became balanced. We had to add more well water and it has become green again and has phospha?

Answer 1

this is much simpler than you are allowing it to be. if it is much concern to you have the water tested. if thais doesnt help take a soil sample and have it tested in a university geology lab. the mineral content alone should answer the question. i would offer more insight but without more specific geological information i cant. it occurs to me that the answer is more in the soil than the water. check for possible pollutants.
