2  · 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.
