WP_20150713_18_07_12_Pro.jpgSo I have very low calcium in my water, like 80. I know that is irrelevant to my pool because it's vinyl, my concern is the deck and coping. I went with the concrete/coolcrete coping because it looks great, but will the low calcium be an issue long term? I have 4 deck jets and while they run I have a lot of splashing. Will this with the low calcium ultimately cause issues?
