Spacare Calcium Hardness Enhancer 500g
Spacare Calcium Hardness Enhancer 500g
Calcium Hardness Enhancer increases the Calcium Hardness level in spa & hot tub water. Water which is low in calcium can corrode equipment, etch concrete and grouted surface, and provide an environment favourable to algal growth.
General Instructions:
The Calcium Hardness level of a spa and hot tub should always be maintained between 200 and 275ppm for concrete and tiled spas and hot tubs, and between 175 and 225ppm for other surfaces. Use a test kit to measure calcium hardness.
