## Description

Product description Raises calcium levels of your pool. Directions Raises calcium levels of your pool.

Review: Works great and much more affordable than others I have tried.
Review: Chlorine, bromine pH, and hardness. My spa has given me a science refresher, that showed me I wasn’t sure I actually learned that science to begin with. And, since pool service providers only care for spas if you have a pool, I have no pool service. Anyway, a couple of carefully worded questions to AI led me to what I needed, and the test strips are happy! The water is clear, the chemicals dissolved with out issue or smell. Five stars
