I have no doubt that MM is sequestering the metals quite effectively for you. I am not doubting it does not "work." But, I simply don't believe it has the power to remove metals from the water by crystalizing. Testing my water after it is "clear" of metals after using MM still yields an iron content in the water - the product is NOT physically removing the metals. If you look at the MSDS it is similar to other type of products on the market. I'm afraid there is no silver bullet here, as JasonLion points out.
I'm glad the product is working for you!! It worked for me VERY effectively the last 2 seasons. This season, it is working, but for some reason, it is not holding for as long as it did the last few seasons.
Again - I added 2 Gallons - that's 8 quarts over 45 days. At one time, there was over a gallon in the water over a few days which surely is OVER what you are saying at 1 qt/2500 gallons.
Currently, I'm stain free about 7 days and counting, which is the longest I've gone this season. However, the pool is testing at .15ppm iron.
