This Spa Wise granular chlorine for spas is a cost-effective, popular sanitiser that eliminates harmful bacteria and viruses while helping keep your water clear and bright. Being spa-specific, it’s gentler than pool chlorine, which can be too harsh for spa use.
Fast-dissolving and de-dusted, it’s ideal for routine sanitation without leaving residue. When adding chlorine, run the jets and leave the cover off for at least 15 minutes to protect headrests and covers. As a guide, use one teaspoon per bather per use, and test regularly to keep free chlorine between 1-3ppm – an ozone or UV system can help reduce overall chlorine demand.
