INCREASES POOL AND SPA WATER HARDNESS

HASA Calcium Chloride is used to increase the calcium hardness of pool and spa water. Plaster pool surfaces may etch if calcium hardness is below 175 ppm. Test the water with a reliable test kit. Acceptable calcium hardness is within a 175-275 ppm range.

DIRECTIONS FOR USE:One pound of HASA Calcium Chloride in a 10,000 gallon pool will increase the calcium hardness 4 ppm. Add this product slowly through the pool or spa skimmer with pump running. Do not clean filter until material has completely dissolved. Re-test pool/spa water after 24 hours and reapply as necessary. Do not overheat.
