The pool company did in fact have me add Calcium Chloride Flake to raise the Calcium Hardness when the initial results were 95. I told them that I had read (on this forum) that Vinyl pools didn't need Calcuim, but they told me that I still need to maintain a certain level to prevent damage in my pool lines and my pool pump parts.

When I was refering to shock, the product is Chlorinated Granules. The main ingredient is Calcium Hypochlorite (47%). The labels dont break the other items down.
