Calcium Chloride 83-87% Granulated
Product Description
Calcium Chloride 83-87% Granulated is composed of white, sugar-sized granules. It is well suited for applications where rapid dissolution of a solid calcium chloride product is required.

Storage & Shelf Life
Store in a dry area, and tightly reseal after each use. To maintain product quality while in storage, solid calcium chloride must be protected from moisture. If the product is on a pallet covered by an intact plastic shroud, it can be stored outdoors on a well-drained surface. If the shroud is torn, pierced, or removed, then the palletized product should be stored indoors or under a waterproof covering.
When properly stored to protect from moisture contact, the expected shelf life for all calcium chloride packaged products is 36 months from the date of manufacture. Calcium chloride does not degrade or deteriorate; however, the shelf life is limited based on the potential for moisture intrusion into the product. Moisture will cause a decrease in overall calcium chloride assay and may cause product clumping. Solid calcium chloride absorbs moisture from the air (i.e., is hygroscopic), even to the point of converting to liquid brine (i.e., is deliquescent).

Calcium Chloride 83-87% Granulated FAQ's
First, determine the amount of dry calcium chloride to mix with water using our helpful Making Solutions Calculator tool.
Always start with cool water and add the solid calcium chloride slowly to the water while continuously mixing. Significant heat is released when dissolving solid calcium chloride, and a temperature increase will occur. For example, when dissolving DOWFLAKE® Xtra 83-87% Calcium Chloride Flakes while making up a 30% solution, the temperature can be expected to increase almost 84°F.
If solids are allowed to sit motionless while in contact with water, a hard cake will form that will be slow to dissolve.
The pH reading for an undiluted sample of 35% solution is approximately 9. OxyChem calcium chloride products are alkaline due to the presence of a slight calcium hydroxide impurity.
Accurate and consistent pH measurement in concentrated salt solutions can be challenging. Results vary depending on the pH probe used and the degree of sample dilution.

Yes. To increase the calcium hardness by 10 ppm in 10,000 gallons of water, add one pound of DOWFLAKE® Xtra 83-87% Calcium Chloride Flakes. Solid calcium chloride currently manufactured by OxyChem contains bromide. While the presence of bromide in pool and spa water is not uncommon (it is often present in disinfectants), it can react with other chemicals to form unwanted disinfection by-products.
