Crystal Waters Pool Hardness Increaser  is used to raise the Calcium Hardness level in your water. This can be known as Calcium, or Total Hardness. Water low on calcium can draw it out of other metals in your pool, corroding the equipment, and provide an environment favourable to algal growth. 

Dosage: To raise Calcium Hardness by 10ppm, add 100g per 10,000L. 
Recommended Calcium level: 80ppm-500ppm 
Active constituent: Calcium Chloride
