The only potential issue that I see is the iron in the water. With softening, we don't see a problem with the water. But the unsoftened water has left iron stains on my walkways and foundation. Last year I switched all of my sprinklers over to softened water (moved where we tap into the water supply to after the softener). I wonder if I can just add Calcium to the pool as it fills? Is that something you can buy?
