Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Dolomite, CaMg(CO3)2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium. Calcite in limestone is divided into low-magnesium and high-ma

Plaster etching. To understand calcium hardness, know that water will seek balance on its own. In other words, if your fill water is "soft" (low calcium hardness), but wants to be higher, it will draw calcium from anywhere it can —namely, the plaster surface of your pool. Calcium being drawn from the plaster into solution is known as etching.
