I believe I have some Iron in my fill water, so I have been using a maintenance dose of Pro Team Metal Magic in my pool. The instructions for Metal Magic say that the sequestrant crystallizes the metal and allows it to be removed by the filter. If this is the case, does a maintenance dose need to be used, or only add the Metal Magic when I need to top off my pool?
I had some brown stains on my stairs, but removed them using a product I bought at the pool store (before I found this site, probably ascorbic acid?). So, I'm not seeing much currently for signs of staining, but want to stay ahead of the game.
