SpaGuard Balance Pak 300 is used to raise Calcium Hardness in spa water.
Plaster etched by low Calcium Hardness will become abrasive and uncomfortable for bathers.
Rough plaster makes cleaning difficult and increases algae problems.
The Calcium Hardness level in spa water should be maintained at 100-200ppm. Never allow Calcium Hardness to fall below 100ppm.
SpaGuard Balance Pak 300 is recommened to be divided into thirds as we do not want to cloud the water and scale up the filter.
