Swim Spa Calcium Enhancer 500gm

Swim Spa Calcium Enhancer 500gm


Crystal Waters Calcium Enhancer 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 swim spa, corroding the equipment, and provide an environment favourable to algal growth. 

Dosage: To raise Calcium Hardness by 10ppm, add 10g per 1000L. 
Recommended Calcium level: 80ppm-140ppm 
Active constituent: Calcium Chloride 
Available sizes: 500g, 4kg (Hardness Increaser)
