How to Lower Calcium Hardness in a Pool: 13 Steps (with
Apr 14, 2020· The calcium hardness should be around 250-350 parts per million (PPM). If the hardness is above 350 PPM, you will need to lower it. If the calcium levels in your pool are regularly above 350 PPM, do a calcium hardness test for your tap water.
Is Limescale Harmful in Drinking Water? | George Brazil
Jul 06, 2017· Limescale is that white, chalky residue left behind by dissolved minerals (mostly calcium and magnesium) in your water. The higher the concentration of minerals in your water, the “harder” your water. So, if you have hard water, you’ve probably seen this white residue in your bathtub, sink or even on your glass dishes.
