Good product that works like advertised.
This worked. Raises the levels for this chemical like a charm. I would recommend placing in a floating chlorine dispenser with the vents shut down to little or no venting. This way it dissolves while floating around instead of sitting on the bottom, the granules don’t dissolve well once they sink to the bottom. Tested before and after and it raised the PH level just as we needed.

This Pool Mate product raises the calcium hardness in pool water. It dissolves easily, rapidly raises the hardness and is very reasonably priced when purchased in the 25 pound size.
