Calcium Chloride Flakes 25kg

In order to keep the calcium hardness of your swimming pool at a good level, use calcium chloride flakes. As well as making the water look particularly clear and inviting, using calcium chloride flakes is also essential for maintaining the structural health of the plaster. Ordinarily, the proper range of calcium hardness for most plaster pools is about 250 parts per million (ppm). Vinyl pools require less calcium chloride.
